Introduction
Laravel's database query builder provides a convenient, fluent interface to creating and running database queries. It can be used to perform most database operations in your application and works perfectly with all of Laravel's supported database systems.
The Laravel query builder uses PDO parameter binding to protect your application against SQL injection attacks. There is no need to clean or sanitize strings passed to the query builder as query bindings.
PDO does not support binding column names. Therefore, you should never allow user input to dictate the column names referenced by your queries, including "order by" columns.
Running Database Queries
Retrieving All Rows From a Table
You may use the table method provided by the DB facade to begin a query.
The table method returns a fluent query builder instance for the given
table, allowing you to chain more constraints onto the query and then finally
retrieve the results of the query using the get method:
1<?php
2
3namespace App\Http\Controllers;
4
5use Illuminate\Support\Facades\DB;
6use Illuminate\View\View;
7
8class UserController extends Controller
9{
10 /**
11 * Show a list of all of the application's users.
12 */
13 public function index(): View
14 {
15 $users = DB::table('users')->get();
16
17 return view('user.index', ['users' => $users]);
18 }
19}
<?php
namespace App\Http\Controllers;
use Illuminate\Support\Facades\DB;
use Illuminate\View\View;
class UserController extends Controller
{
/**
* Show a list of all of the application's users.
*/
public function index(): View
{
$users = DB::table('users')->get();
return view('user.index', ['users' => $users]);
}
}
The get method returns an Illuminate\Support\Collection instance
containing the results of the query where each result is an instance of the
PHP stdClass object. You may access each column's value by accessing the
column as a property of the object:
1use Illuminate\Support\Facades\DB;
2
3$users = DB::table('users')->get();
4
5foreach ($users as $user) {
6 echo $user->name;
7}
use Illuminate\Support\Facades\DB;
$users = DB::table('users')->get();
foreach ($users as $user) {
echo $user->name;
}
Laravel collections provide a variety of extremely powerful methods for mapping and reducing data. For more information on Laravel collections, check out the collection documentation.
Retrieving a Single Row / Column From a Table
If you just need to retrieve a single row from a database table, you may use
the DB facade's first method. This method will return a single stdClass
object:
1$user = DB::table('users')->where('name', 'John')->first();
2
3return $user->email;
$user = DB::table('users')->where('name', 'John')->first();
return $user->email;
If you would like to retrieve a single row from a database table, but throw an
Illuminate\Database\RecordNotFoundException if no matching row is found, you
may use the firstOrFail method. If the RecordNotFoundException is not
caught, a 404 HTTP response is automatically sent back to the client:
1$user = DB::table('users')->where('name', 'John')->firstOrFail();
$user = DB::table('users')->where('name', 'John')->firstOrFail();
If you don't need an entire row, you may extract a single value from a record
using the value method. This method will return the value of the column
directly:
1$email = DB::table('users')->where('name', 'John')->value('email');
$email = DB::table('users')->where('name', 'John')->value('email');
To retrieve a single row by its id column value, use the find method:
1$user = DB::table('users')->find(3);
$user = DB::table('users')->find(3);
Retrieving a List of Column Values
If you would like to retrieve an Illuminate\Support\Collection instance
containing the values of a single column, you may use the pluck method. In
this example, we'll retrieve a collection of user titles:
1use Illuminate\Support\Facades\DB;
2
3$titles = DB::table('users')->pluck('title');
4
5foreach ($titles as $title) {
6 echo $title;
7}
use Illuminate\Support\Facades\DB;
$titles = DB::table('users')->pluck('title');
foreach ($titles as $title) {
echo $title;
}
You may specify the column that the resulting collection should use as its
keys by providing a second argument to the pluck method:
1$titles = DB::table('users')->pluck('title', 'name');
2
3foreach ($titles as $name => $title) {
4 echo $title;
5}
$titles = DB::table('users')->pluck('title', 'name');
foreach ($titles as $name => $title) {
echo $title;
}
Chunking Results
If you need to work with thousands of database records, consider using the
chunk method provided by the DB facade. This method retrieves a small
chunk of results at a time and feeds each chunk into a closure for processing.
For example, let's retrieve the entire users table in chunks of 100 records
at a time:
1use Illuminate\Support\Collection;
2use Illuminate\Support\Facades\DB;
3
4DB::table('users')->orderBy('id')->chunk(100, function (Collection $users) {
5 foreach ($users as $user) {
6 // ...
7 }
8});
use Illuminate\Support\Collection;
use Illuminate\Support\Facades\DB;
DB::table('users')->orderBy('id')->chunk(100, function (Collection $users) {
foreach ($users as $user) {
// ...
}
});
You may stop further chunks from being processed by returning false from the
closure:
1DB::table('users')->orderBy('id')->chunk(100, function (Collection $users) {
2 // Process the records...
3
4 return false;
5});
DB::table('users')->orderBy('id')->chunk(100, function (Collection $users) {
// Process the records...
return false;
});
If you are updating database records while chunking results, your chunk
results could change in unexpected ways. If you plan to update the retrieved
records while chunking, it is always best to use the chunkById method
instead. This method will automatically paginate the results based on the
record's primary key:
1DB::table('users')->where('active', false)
2 ->chunkById(100, function (Collection $users) {
3 foreach ($users as $user) {
4 DB::table('users')
5 ->where('id', $user->id)
6 ->update(['active' => true]);
7 }
8 });
DB::table('users')->where('active', false)
->chunkById(100, function (Collection $users) {
foreach ($users as $user) {
DB::table('users')
->where('id', $user->id)
->update(['active' => true]);
}
});
Since the chunkById and lazyById methods add their own "where" conditions
to the query being executed, you should typically logically group your own
conditions within a closure:
1DB::table('users')->where(function ($query) {
2 $query->where('credits', 1)->orWhere('credits', 2);
3})->chunkById(100, function (Collection $users) {
4 foreach ($users as $user) {
5 DB::table('users')
6 ->where('id', $user->id)
7 ->update(['credits' => 3]);
8 }
9});
DB::table('users')->where(function ($query) {
$query->where('credits', 1)->orWhere('credits', 2);
})->chunkById(100, function (Collection $users) {
foreach ($users as $user) {
DB::table('users')
->where('id', $user->id)
->update(['credits' => 3]);
}
});
When updating or deleting records inside the chunk callback, any changes to the primary key or foreign keys could affect the chunk query. This could potentially result in records not being included in the chunked results.
Streaming Results Lazily
The lazy method works similarly to the chunk method in the sense that it
executes the query in chunks. However, instead of passing each chunk into a
callback, the lazy() method returns a
LazyCollection, which lets you
interact with the results as a single stream:
1use Illuminate\Support\Facades\DB;
2
3DB::table('users')->orderBy('id')->lazy()->each(function (object $user) {
4 // ...
5});
use Illuminate\Support\Facades\DB;
DB::table('users')->orderBy('id')->lazy()->each(function (object $user) {
// ...
});
Once again, if you plan to update the retrieved records while iterating over
them, it is best to use the lazyById or lazyByIdDesc methods instead.
These methods will automatically paginate the results based on the record's
primary key:
1DB::table('users')->where('active', false)
2 ->lazyById()->each(function (object $user) {
3 DB::table('users')
4 ->where('id', $user->id)
5 ->update(['active' => true]);
6 });
DB::table('users')->where('active', false)
->lazyById()->each(function (object $user) {
DB::table('users')
->where('id', $user->id)
->update(['active' => true]);
});
When updating or deleting records while iterating over them, any changes to the primary key or foreign keys could affect the chunk query. This could potentially result in records not being included in the results.
Aggregates
The query builder also provides a variety of methods for retrieving aggregate
values like count, max, min, avg, and sum. You may call any of these
methods after constructing your query:
1use Illuminate\Support\Facades\DB;
2
3$users = DB::table('users')->count();
4
5$price = DB::table('orders')->max('price');
use Illuminate\Support\Facades\DB;
$users = DB::table('users')->count();
$price = DB::table('orders')->max('price');
Of course, you may combine these methods with other clauses to fine-tune how your aggregate value is calculated:
1$price = DB::table('orders')
2 ->where('finalized', 1)
3 ->avg('price');
$price = DB::table('orders')
->where('finalized', 1)
->avg('price');
Determining if Records Exist
Instead of using the count method to determine if any records exist that
match your query's constraints, you may use the exists and doesntExist
methods:
1if (DB::table('orders')->where('finalized', 1)->exists()) {
2 // ...
3}
4
5if (DB::table('orders')->where('finalized', 1)->doesntExist()) {
6 // ...
7}
if (DB::table('orders')->where('finalized', 1)->exists()) {
// ...
}
if (DB::table('orders')->where('finalized', 1)->doesntExist()) {
// ...
}
Select Statements
Specifying a Select Clause
You may not always want to select all columns from a database table. Using the
select method, you can specify a custom "select" clause for the query:
1use Illuminate\Support\Facades\DB;
2
3$users = DB::table('users')
4 ->select('name', 'email as user_email')
5 ->get();
use Illuminate\Support\Facades\DB;
$users = DB::table('users')
->select('name', 'email as user_email')
->get();
The distinct method allows you to force the query to return distinct
results:
1$users = DB::table('users')->distinct()->get();
$users = DB::table('users')->distinct()->get();
If you already have a query builder instance and you wish to add a column to
its existing select clause, you may use the addSelect method:
1$query = DB::table('users')->select('name');
2
3$users = $query->addSelect('age')->get();
$query = DB::table('users')->select('name');
$users = $query->addSelect('age')->get();
Raw Expressions
Sometimes you may need to insert an arbitrary string into a query. To create a
raw string expression, you may use the raw method provided by the DB
facade:
1$users = DB::table('users')
2 ->select(DB::raw('count(*) as user_count, status'))
3 ->where('status', '<>', 1)
4 ->groupBy('status')
5 ->get();
$users = DB::table('users')
->select(DB::raw('count(*) as user_count, status'))
->where('status', '<>', 1)
->groupBy('status')
->get();
Raw statements will be injected into the query as strings, so you should be extremely careful to avoid creating SQL injection vulnerabilities.
Raw Methods
Instead of using the DB::raw method, you may also use the following methods
to insert a raw expression into various parts of your query. Remember,
Laravel cannot guarantee that any query using raw expressions is protected
against SQL injection vulnerabilities.
selectRaw
The selectRaw method can be used in place of addSelect(DB::raw(/* ... */)). This method accepts an optional array of bindings as its second
argument:
1$orders = DB::table('orders')
2 ->selectRaw('price * ? as price_with_tax', [1.0825])
3 ->get();
$orders = DB::table('orders')
->selectRaw('price * ? as price_with_tax', [1.0825])
->get();
whereRaw / orWhereRaw
The whereRaw and orWhereRaw methods can be used to inject a raw "where"
clause into your query. These methods accept an optional array of bindings as
their second argument:
1$orders = DB::table('orders')
2 ->whereRaw('price > IF(state = "TX", ?, 100)', [200])
3 ->get();
$orders = DB::table('orders')
->whereRaw('price > IF(state = "TX", ?, 100)', [200])
->get();
havingRaw / orHavingRaw
The havingRaw and orHavingRaw methods may be used to provide a raw string
as the value of the "having" clause. These methods accept an optional array of
bindings as their second argument:
1$orders = DB::table('orders')
2 ->select('department', DB::raw('SUM(price) as total_sales'))
3 ->groupBy('department')
4 ->havingRaw('SUM(price) > ?', [2500])
5 ->get();
$orders = DB::table('orders')
->select('department', DB::raw('SUM(price) as total_sales'))
->groupBy('department')
->havingRaw('SUM(price) > ?', [2500])
->get();
orderByRaw
The orderByRaw method may be used to provide a raw string as the value of
the "order by" clause:
1$orders = DB::table('orders')
2 ->orderByRaw('updated_at - created_at DESC')
3 ->get();
$orders = DB::table('orders')
->orderByRaw('updated_at - created_at DESC')
->get();
groupByRaw
The groupByRaw method may be used to provide a raw string as the value of
the group by clause:
1$orders = DB::table('orders')
2 ->select('city', 'state')
3 ->groupByRaw('city, state')
4 ->get();
$orders = DB::table('orders')
->select('city', 'state')
->groupByRaw('city, state')
->get();
Joins
Inner Join Clause
The query builder may also be used to add join clauses to your queries. To
perform a basic "inner join", you may use the join method on a query builder
instance. The first argument passed to the join method is the name of the
table you need to join to, while the remaining arguments specify the column
constraints for the join. You may even join multiple tables in a single query:
1use Illuminate\Support\Facades\DB;
2
3$users = DB::table('users')
4 ->join('contacts', 'users.id', '=', 'contacts.user_id')
5 ->join('orders', 'users.id', '=', 'orders.user_id')
6 ->select('users.*', 'contacts.phone', 'orders.price')
7 ->get();
use Illuminate\Support\Facades\DB;
$users = DB::table('users')
->join('contacts', 'users.id', '=', 'contacts.user_id')
->join('orders', 'users.id', '=', 'orders.user_id')
->select('users.*', 'contacts.phone', 'orders.price')
->get();
Left Join / Right Join Clause
If you would like to perform a "left join" or "right join" instead of an
"inner join", use the leftJoin or rightJoin methods. These methods have
the same signature as the join method:
1$users = DB::table('users')
2 ->leftJoin('posts', 'users.id', '=', 'posts.user_id')
3 ->get();
4
5$users = DB::table('users')
6 ->rightJoin('posts', 'users.id', '=', 'posts.user_id')
7 ->get();
$users = DB::table('users')
->leftJoin('posts', 'users.id', '=', 'posts.user_id')
->get();
$users = DB::table('users')
->rightJoin('posts', 'users.id', '=', 'posts.user_id')
->get();
Cross Join Clause
You may use the crossJoin method to perform a "cross join". Cross joins
generate a cartesian product between the first table and the joined table:
1$sizes = DB::table('sizes')
2 ->crossJoin('colors')
3 ->get();
$sizes = DB::table('sizes')
->crossJoin('colors')
->get();
Advanced Join Clauses
You may also specify more advanced join clauses. To get started, pass a
closure as the second argument to the join method. The closure will receive
a Illuminate\Database\Query\JoinClause instance which allows you to specify
constraints on the "join" clause:
1DB::table('users')
2 ->join('contacts', function (JoinClause $join) {
3 $join->on('users.id', '=', 'contacts.user_id')->orOn(/* ... */);
4 })
5 ->get();
DB::table('users')
->join('contacts', function (JoinClause $join) {
$join->on('users.id', '=', 'contacts.user_id')->orOn(/* ... */);
})
->get();
If you would like to use a "where" clause on your joins, you may use the
where and orWhere methods provided by the JoinClause instance. Instead
of comparing two columns, these methods will compare the column against a
value:
1DB::table('users')
2 ->join('contacts', function (JoinClause $join) {
3 $join->on('users.id', '=', 'contacts.user_id')
4 ->where('contacts.user_id', '>', 5);
5 })
6 ->get();
DB::table('users')
->join('contacts', function (JoinClause $join) {
$join->on('users.id', '=', 'contacts.user_id')
->where('contacts.user_id', '>', 5);
})
->get();
Subquery Joins
You may use the joinSub, leftJoinSub, and rightJoinSub methods to join a
query to a subquery. Each of these methods receives three arguments: the
subquery, its table alias, and a closure that defines the related columns. In
this example, we will retrieve a collection of users where each user record
also contains the created_at timestamp of the user's most recently published
blog post:
1$latestPosts = DB::table('posts')
2 ->select('user_id', DB::raw('MAX(created_at) as last_post_created_at'))
3 ->where('is_published', true)
4 ->groupBy('user_id');
5
6$users = DB::table('users')
7 ->joinSub($latestPosts, 'latest_posts', function (JoinClause $join) {
8 $join->on('users.id', '=', 'latest_posts.user_id');
9 })->get();
$latestPosts = DB::table('posts')
->select('user_id', DB::raw('MAX(created_at) as last_post_created_at'))
->where('is_published', true)
->groupBy('user_id');
$users = DB::table('users')
->joinSub($latestPosts, 'latest_posts', function (JoinClause $join) {
$join->on('users.id', '=', 'latest_posts.user_id');
})->get();
Lateral Joins
Lateral joins are currently supported by PostgreSQL, MySQL >= 8.0.14, and SQL Server.
You may use the joinLateral and leftJoinLateral methods to perform a
"lateral join" with a subquery. Each of these methods receives two arguments:
the subquery and its table alias. The join condition(s) should be specified
within the where clause of the given subquery. Lateral joins are evaluated
for each row and can reference columns outside the subquery.
In this example, we will retrieve a collection of users as well as the user's
three most recent blog posts. Each user can produce up to three rows in the
result set: one for each of their most recent blog posts. The join condition
is specified with a whereColumn clause within the subquery, referencing the
current user row:
1$latestPosts = DB::table('posts')
2 ->select('id as post_id', 'title as post_title', 'created_at as post_created_at')
3 ->whereColumn('user_id', 'users.id')
4 ->orderBy('created_at', 'desc')
5 ->limit(3);
6
7$users = DB::table('users')
8 ->joinLateral($latestPosts, 'latest_posts')
9 ->get();
$latestPosts = DB::table('posts')
->select('id as post_id', 'title as post_title', 'created_at as post_created_at')
->whereColumn('user_id', 'users.id')
->orderBy('created_at', 'desc')
->limit(3);
$users = DB::table('users')
->joinLateral($latestPosts, 'latest_posts')
->get();
Unions
The query builder also provides a convenient method to "union" two or more
queries together. For example, you may create an initial query and use the
union method to union it with more queries:
1use Illuminate\Support\Facades\DB;
2
3$first = DB::table('users')
4 ->whereNull('first_name');
5
6$users = DB::table('users')
7 ->whereNull('last_name')
8 ->union($first)
9 ->get();
use Illuminate\Support\Facades\DB;
$first = DB::table('users')
->whereNull('first_name');
$users = DB::table('users')
->whereNull('last_name')
->union($first)
->get();
In addition to the union method, the query builder provides a unionAll
method. Queries that are combined using the unionAll method will not have
their duplicate results removed. The unionAll method has the same method
signature as the union method.
Basic Where Clauses
Where Clauses
You may use the query builder's where method to add "where" clauses to the
query. The most basic call to the where method requires three arguments. The
first argument is the name of the column. The second argument is an operator,
which can be any of the database's supported operators. The third argument is
the value to compare against the column's value.
For example, the following query retrieves users where the value of the
votes column is equal to 100 and the value of the age column is greater
than 35:
1$users = DB::table('users')
2 ->where('votes', '=', 100)
3 ->where('age', '>', 35)
4 ->get();
$users = DB::table('users')
->where('votes', '=', 100)
->where('age', '>', 35)
->get();
For convenience, if you want to verify that a column is = to a given value,
you may pass the value as the second argument to the where method. Laravel
will assume you would like to use the = operator:
1$users = DB::table('users')->where('votes', 100)->get();
$users = DB::table('users')->where('votes', 100)->get();
You may also provide an associative array to the where method to quickly
query against multiple columns:
1$users = DB::table('users')->where([
2 'first_name' => 'Jane',
3 'last_name' => 'Doe',
4])->get();
$users = DB::table('users')->where([
'first_name' => 'Jane',
'last_name' => 'Doe',
])->get();
As previously mentioned, you may use any operator that is supported by your database system:
1$users = DB::table('users')
2 ->where('votes', '>=', 100)
3 ->get();
4
5$users = DB::table('users')
6 ->where('votes', '<>', 100)
7 ->get();
8
9$users = DB::table('users')
10 ->where('name', 'like', 'T%')
11 ->get();
$users = DB::table('users')
->where('votes', '>=', 100)
->get();
$users = DB::table('users')
->where('votes', '<>', 100)
->get();
$users = DB::table('users')
->where('name', 'like', 'T%')
->get();
You may also pass an array of conditions to the where function. Each element
of the array should be an array containing the three arguments typically
passed to the where method:
1$users = DB::table('users')->where([
2 ['status', '=', '1'],
3 ['subscribed', '<>', '1'],
4])->get();
$users = DB::table('users')->where([
['status', '=', '1'],
['subscribed', '<>', '1'],
])->get();
PDO does not support binding column names. Therefore, you should never allow user input to dictate the column names referenced by your queries, including "order by" columns.
MySQL and MariaDB automatically typecast strings to integers in string-number
comparisons. In this process, non-numeric strings are converted to 0, which
can lead to unexpected results. For example, if your table has a secret
column with a value of aaa and you run User::where('secret', 0), that row
will be returned. To avoid this, ensure all values are typecast to their
appropriate types before using them in queries.
Or Where Clauses
When chaining together calls to the query builder's where method, the
"where" clauses will be joined together using the and operator. However, you
may use the orWhere method to join a clause to the query using the or
operator. The orWhere method accepts the same arguments as the where
method:
1$users = DB::table('users')
2 ->where('votes', '>', 100)
3 ->orWhere('name', 'John')
4 ->get();
$users = DB::table('users')
->where('votes', '>', 100)
->orWhere('name', 'John')
->get();
If you need to group an "or" condition within parentheses, you may pass a
closure as the first argument to the orWhere method:
1use Illuminate\Database\Query\Builder;
2
3$users = DB::table('users')
4 ->where('votes', '>', 100)
5 ->orWhere(function (Builder $query) {
6 $query->where('name', 'Abigail')
7 ->where('votes', '>', 50);
8 })
9 ->get();
use Illuminate\Database\Query\Builder;
$users = DB::table('users')
->where('votes', '>', 100)
->orWhere(function (Builder $query) {
$query->where('name', 'Abigail')
->where('votes', '>', 50);
})
->get();
The example above will produce the following SQL:
1select * from users where votes > 100 or (name = 'Abigail' and votes > 50)
select * from users where votes > 100 or (name = 'Abigail' and votes > 50)
You should always group orWhere calls in order to avoid unexpected behavior
when global scopes are applied.
Where Not Clauses
The whereNot and orWhereNot methods may be used to negate a given group of
query constraints. For example, the following query excludes products that are
on clearance or which have a price that is less than ten:
1$products = DB::table('products')
2 ->whereNot(function (Builder $query) {
3 $query->where('clearance', true)
4 ->orWhere('price', '<', 10);
5 })
6 ->get();
$products = DB::table('products')
->whereNot(function (Builder $query) {
$query->where('clearance', true)
->orWhere('price', '<', 10);
})
->get();
Where Any / All / None Clauses
Sometimes you may need to apply the same query constraints to multiple
columns. For example, you may want to retrieve all records where any columns
in a given list are LIKE a given value. You may accomplish this using the
whereAny method:
1$users = DB::table('users')
2 ->where('active', true)
3 ->whereAny([
4 'name',
5 'email',
6 'phone',
7 ], 'like', 'Example%')
8 ->get();
$users = DB::table('users')
->where('active', true)
->whereAny([
'name',
'email',
'phone',
], 'like', 'Example%')
->get();
The query above will result in the following SQL:
1SELECT *
2FROM users
3WHERE active = true AND (
4 name LIKE 'Example%' OR
5 email LIKE 'Example%' OR
6 phone LIKE 'Example%'
7)
SELECT *
FROM users
WHERE active = true AND (
name LIKE 'Example%' OR
email LIKE 'Example%' OR
phone LIKE 'Example%'
)
Similarly, the whereAll method may be used to retrieve records where all of
the given columns match a given constraint:
1$posts = DB::table('posts')
2 ->where('published', true)
3 ->whereAll([
4 'title',
5 'content',
6 ], 'like', '%Laravel%')
7 ->get();
$posts = DB::table('posts')
->where('published', true)
->whereAll([
'title',
'content',
], 'like', '%Laravel%')
->get();
The query above will result in the following SQL:
1SELECT *
2FROM posts
3WHERE published = true AND (
4 title LIKE '%Laravel%' AND
5 content LIKE '%Laravel%'
6)
SELECT *
FROM posts
WHERE published = true AND (
title LIKE '%Laravel%' AND
content LIKE '%Laravel%'
)
The whereNone method may be used to retrieve records where none of the given
columns match a given constraint:
1$posts = DB::table('albums')
2 ->where('published', true)
3 ->whereNone([
4 'title',
5 'lyrics',
6 'tags',
7 ], 'like', '%explicit%')
8 ->get();
$posts = DB::table('albums')
->where('published', true)
->whereNone([
'title',
'lyrics',
'tags',
], 'like', '%explicit%')
->get();
The query above will result in the following SQL:
1SELECT *
2FROM albums
3WHERE published = true AND NOT (
4 title LIKE '%explicit%' OR
5 lyrics LIKE '%explicit%' OR
6 tags LIKE '%explicit%'
7)
SELECT *
FROM albums
WHERE published = true AND NOT (
title LIKE '%explicit%' OR
lyrics LIKE '%explicit%' OR
tags LIKE '%explicit%'
)
JSON Where Clauses
Laravel also supports querying JSON column types on databases that provide
support for JSON column types. Currently, this includes MariaDB 10.3+, MySQL
8.0+, PostgreSQL 12.0+, SQL Server 2017+, and SQLite 3.39.0+. To query a JSON
column, use the -> operator:
1$users = DB::table('users')
2 ->where('preferences->dining->meal', 'salad')
3 ->get();
4
5$users = DB::table('users')
6 ->whereIn('preferences->dining->meal', ['pasta', 'salad', 'sandwiches'])
7 ->get();
$users = DB::table('users')
->where('preferences->dining->meal', 'salad')
->get();
$users = DB::table('users')
->whereIn('preferences->dining->meal', ['pasta', 'salad', 'sandwiches'])
->get();
You may use the whereJsonContains and whereJsonDoesntContain methods to
query JSON arrays:
1$users = DB::table('users')
2 ->whereJsonContains('options->languages', 'en')
3 ->get();
4
5$users = DB::table('users')
6 ->whereJsonDoesntContain('options->languages', 'en')
7 ->get();
$users = DB::table('users')
->whereJsonContains('options->languages', 'en')
->get();
$users = DB::table('users')
->whereJsonDoesntContain('options->languages', 'en')
->get();
If your application uses the MariaDB, MySQL, or PostgreSQL databases, you may
pass an array of values to the whereJsonContains and
whereJsonDoesntContain methods:
1$users = DB::table('users')
2 ->whereJsonContains('options->languages', ['en', 'de'])
3 ->get();
4
5$users = DB::table('users')
6 ->whereJsonDoesntContain('options->languages', ['en', 'de'])
7 ->get();
$users = DB::table('users')
->whereJsonContains('options->languages', ['en', 'de'])
->get();
$users = DB::table('users')
->whereJsonDoesntContain('options->languages', ['en', 'de'])
->get();
In addition, you may use the whereJsonContainsKey or
whereJsonDoesntContainKey methods to retrieve the results that include or do
not include a JSON key:
1$users = DB::table('users')
2 ->whereJsonContainsKey('preferences->dietary_requirements')
3 ->get();
4
5$users = DB::table('users')
6 ->whereJsonDoesntContainKey('preferences->dietary_requirements')
7 ->get();
$users = DB::table('users')
->whereJsonContainsKey('preferences->dietary_requirements')
->get();
$users = DB::table('users')
->whereJsonDoesntContainKey('preferences->dietary_requirements')
->get();
Finally, you may use whereJsonLength method to query JSON arrays by their
length:
1$users = DB::table('users')
2 ->whereJsonLength('options->languages', 0)
3 ->get();
4
5$users = DB::table('users')
6 ->whereJsonLength('options->languages', '>', 1)
7 ->get();
$users = DB::table('users')
->whereJsonLength('options->languages', 0)
->get();
$users = DB::table('users')
->whereJsonLength('options->languages', '>', 1)
->get();
Additional Where Clauses
whereLike / orWhereLike / whereNotLike / orWhereNotLike
The whereLike method allows you to add "LIKE" clauses to your query for
pattern matching. These methods provide a database-agnostic way of performing
string matching queries, with the ability to toggle case-sensitivity. By
default, string matching is case-insensitive:
1$users = DB::table('users')
2 ->whereLike('name', '%John%')
3 ->get();
$users = DB::table('users')
->whereLike('name', '%John%')
->get();
You can enable a case-sensitive search via the caseSensitive argument:
1$users = DB::table('users')
2 ->whereLike('name', '%John%', caseSensitive: true)
3 ->get();
$users = DB::table('users')
->whereLike('name', '%John%', caseSensitive: true)
->get();
The orWhereLike method allows you to add an "or" clause with a LIKE
condition:
1$users = DB::table('users')
2 ->where('votes', '>', 100)
3 ->orWhereLike('name', '%John%')
4 ->get();
$users = DB::table('users')
->where('votes', '>', 100)
->orWhereLike('name', '%John%')
->get();
The whereNotLike method allows you to add "NOT LIKE" clauses to your query:
1$users = DB::table('users')
2 ->whereNotLike('name', '%John%')
3 ->get();
$users = DB::table('users')
->whereNotLike('name', '%John%')
->get();
Similarly, you can use orWhereNotLike to add an "or" clause with a NOT LIKE
condition:
1$users = DB::table('users')
2 ->where('votes', '>', 100)
3 ->orWhereNotLike('name', '%John%')
4 ->get();
$users = DB::table('users')
->where('votes', '>', 100)
->orWhereNotLike('name', '%John%')
->get();
The whereLike case-sensitive search option is currently not supported on SQL
Server.
whereIn / whereNotIn / orWhereIn / orWhereNotIn
The whereIn method verifies that a given column's value is contained within
the given array:
1$users = DB::table('users')
2 ->whereIn('id', [1, 2, 3])
3 ->get();
$users = DB::table('users')
->whereIn('id', [1, 2, 3])
->get();
The whereNotIn method verifies that the given column's value is not
contained in the given array:
1$users = DB::table('users')
2 ->whereNotIn('id', [1, 2, 3])
3 ->get();
$users = DB::table('users')
->whereNotIn('id', [1, 2, 3])
->get();
You may also provide a query object as the whereIn method's second argument:
1$activeUsers = DB::table('users')->select('id')->where('is_active', 1);
2
3$users = DB::table('comments')
4 ->whereIn('user_id', $activeUsers)
5 ->get();
$activeUsers = DB::table('users')->select('id')->where('is_active', 1);
$users = DB::table('comments')
->whereIn('user_id', $activeUsers)
->get();
The example above will produce the following SQL:
1select * from comments where user_id in (
2 select id
3 from users
4 where is_active = 1
5)
select * from comments where user_id in (
select id
from users
where is_active = 1
)
If you are adding a large array of integer bindings to your query, the
whereIntegerInRaw or whereIntegerNotInRaw methods may be used to greatly
reduce your memory usage.
whereBetween / orWhereBetween
The whereBetween method verifies that a column's value is between two
values:
1$users = DB::table('users')
2 ->whereBetween('votes', [1, 100])
3 ->get();
$users = DB::table('users')
->whereBetween('votes', [1, 100])
->get();
whereNotBetween / orWhereNotBetween
The whereNotBetween method verifies that a column's value lies outside of
two values:
1$users = DB::table('users')
2 ->whereNotBetween('votes', [1, 100])
3 ->get();
$users = DB::table('users')
->whereNotBetween('votes', [1, 100])
->get();
whereBetweenColumns / whereNotBetweenColumns / orWhereBetweenColumns / orWhereNotBetweenColumns
The whereBetweenColumns method verifies that a column's value is between the
two values of two columns in the same table row:
1$patients = DB::table('patients')
2 ->whereBetweenColumns('weight', ['minimum_allowed_weight', 'maximum_allowed_weight'])
3 ->get();
$patients = DB::table('patients')
->whereBetweenColumns('weight', ['minimum_allowed_weight', 'maximum_allowed_weight'])
->get();
The whereNotBetweenColumns method verifies that a column's value lies
outside the two values of two columns in the same table row:
1$patients = DB::table('patients')
2 ->whereNotBetweenColumns('weight', ['minimum_allowed_weight', 'maximum_allowed_weight'])
3 ->get();
$patients = DB::table('patients')
->whereNotBetweenColumns('weight', ['minimum_allowed_weight', 'maximum_allowed_weight'])
->get();
whereValueBetween / whereValueNotBetween / orWhereValueBetween / orWhereValueNotBetween
The whereValueBetween method verifies that a given value is between the
values of two columns of the same type in the same table row:
1$patients = DB::table('products')
2 ->whereValueBetween(100, ['min_price', 'max_price'])
3 ->get();
$patients = DB::table('products')
->whereValueBetween(100, ['min_price', 'max_price'])
->get();
The whereValueNotBetween method verifies that a value lies outside the
values of two columns in the same table row:
1$patients = DB::table('products')
2 ->whereValueNotBetween(100, ['min_price', 'max_price'])
3 ->get();
$patients = DB::table('products')
->whereValueNotBetween(100, ['min_price', 'max_price'])
->get();
whereNull / whereNotNull / orWhereNull / orWhereNotNull
The whereNull method verifies that the value of the given column is NULL:
1$users = DB::table('users')
2 ->whereNull('updated_at')
3 ->get();
$users = DB::table('users')
->whereNull('updated_at')
->get();
The whereNotNull method verifies that the column's value is not NULL:
1$users = DB::table('users')
2 ->whereNotNull('updated_at')
3 ->get();
$users = DB::table('users')
->whereNotNull('updated_at')
->get();
whereDate / whereMonth / whereDay / whereYear / whereTime
The whereDate method may be used to compare a column's value against a date:
1$users = DB::table('users')
2 ->whereDate('created_at', '2016-12-31')
3 ->get();
$users = DB::table('users')
->whereDate('created_at', '2016-12-31')
->get();
The whereMonth method may be used to compare a column's value against a
specific month:
1$users = DB::table('users')
2 ->whereMonth('created_at', '12')
3 ->get();
$users = DB::table('users')
->whereMonth('created_at', '12')
->get();
The whereDay method may be used to compare a column's value against a
specific day of the month:
1$users = DB::table('users')
2 ->whereDay('created_at', '31')
3 ->get();
$users = DB::table('users')
->whereDay('created_at', '31')
->get();
The whereYear method may be used to compare a column's value against a
specific year:
1$users = DB::table('users')
2 ->whereYear('created_at', '2016')
3 ->get();
$users = DB::table('users')
->whereYear('created_at', '2016')
->get();
The whereTime method may be used to compare a column's value against a
specific time:
1$users = DB::table('users')
2 ->whereTime('created_at', '=', '11:20:45')
3 ->get();
$users = DB::table('users')
->whereTime('created_at', '=', '11:20:45')
->get();
wherePast / whereFuture / whereToday / whereBeforeToday / whereAfterToday
The wherePast and whereFuture methods may be used to determine if a
column's value is in the past or future:
1$invoices = DB::table('invoices')
2 ->wherePast('due_at')
3 ->get();
4
5$invoices = DB::table('invoices')
6 ->whereFuture('due_at')
7 ->get();
$invoices = DB::table('invoices')
->wherePast('due_at')
->get();
$invoices = DB::table('invoices')
->whereFuture('due_at')
->get();
The whereNowOrPast and whereNowOrFuture methods may be used to determine
if a column's value is in the past or future, inclusive of the current date
and time:
1$invoices = DB::table('invoices')
2 ->whereNowOrPast('due_at')
3 ->get();
4
5$invoices = DB::table('invoices')
6 ->whereNowOrFuture('due_at')
7 ->get();
$invoices = DB::table('invoices')
->whereNowOrPast('due_at')
->get();
$invoices = DB::table('invoices')
->whereNowOrFuture('due_at')
->get();
The whereToday, whereBeforeToday, and whereAfterToday methods may be
used to determine if a column's value is today, before today, or after today,
respectively:
1$invoices = DB::table('invoices')
2 ->whereToday('due_at')
3 ->get();
4
5$invoices = DB::table('invoices')
6 ->whereBeforeToday('due_at')
7 ->get();
8
9$invoices = DB::table('invoices')
10 ->whereAfterToday('due_at')
11 ->get();
$invoices = DB::table('invoices')
->whereToday('due_at')
->get();
$invoices = DB::table('invoices')
->whereBeforeToday('due_at')
->get();
$invoices = DB::table('invoices')
->whereAfterToday('due_at')
->get();
Similarly, the whereTodayOrBefore and whereTodayOrAfter methods may be
used to determine if a column's value is before today or after today,
inclusive of today's date:
1$invoices = DB::table('invoices')
2 ->whereTodayOrBefore('due_at')
3 ->get();
4
5$invoices = DB::table('invoices')
6 ->whereTodayOrAfter('due_at')
7 ->get();
$invoices = DB::table('invoices')
->whereTodayOrBefore('due_at')
->get();
$invoices = DB::table('invoices')
->whereTodayOrAfter('due_at')
->get();
whereColumn / orWhereColumn
The whereColumn method may be used to verify that two columns are equal:
1$users = DB::table('users')
2 ->whereColumn('first_name', 'last_name')
3 ->get();
$users = DB::table('users')
->whereColumn('first_name', 'last_name')
->get();
You may also pass a comparison operator to the whereColumn method:
1$users = DB::table('users')
2 ->whereColumn('updated_at', '>', 'created_at')
3 ->get();
$users = DB::table('users')
->whereColumn('updated_at', '>', 'created_at')
->get();
You may also pass an array of column comparisons to the whereColumn method.
These conditions will be joined using the and operator:
1$users = DB::table('users')
2 ->whereColumn([
3 ['first_name', '=', 'last_name'],
4 ['updated_at', '>', 'created_at'],
5 ])->get();
$users = DB::table('users')
->whereColumn([
['first_name', '=', 'last_name'],
['updated_at', '>', 'created_at'],
])->get();
Logical Grouping
Sometimes you may need to group several "where" clauses within parentheses in
order to achieve your query's desired logical grouping. In fact, you should
generally always group calls to the orWhere method in parentheses in order
to avoid unexpected query behavior. To accomplish this, you may pass a closure
to the where method:
1$users = DB::table('users')
2 ->where('name', '=', 'John')
3 ->where(function (Builder $query) {
4 $query->where('votes', '>', 100)
5 ->orWhere('title', '=', 'Admin');
6 })
7 ->get();
$users = DB::table('users')
->where('name', '=', 'John')
->where(function (Builder $query) {
$query->where('votes', '>', 100)
->orWhere('title', '=', 'Admin');
})
->get();
As you can see, passing a closure into the where method instructs the query
builder to begin a constraint group. The closure will receive a query builder
instance which you can use to set the constraints that should be contained
within the parenthesis group. The example above will produce the following
SQL:
1select * from users where name = 'John' and (votes > 100 or title = 'Admin')
select * from users where name = 'John' and (votes > 100 or title = 'Admin')
You should always group orWhere calls in order to avoid unexpected behavior
when global scopes are applied.
Advanced Where Clauses
Where Exists Clauses
The whereExists method allows you to write "where exists" SQL clauses. The
whereExists method accepts a closure which will receive a query builder
instance, allowing you to define the query that should be placed inside of the
"exists" clause:
1$users = DB::table('users')
2 ->whereExists(function (Builder $query) {
3 $query->select(DB::raw(1))
4 ->from('orders')
5 ->whereColumn('orders.user_id', 'users.id');
6 })
7 ->get();
$users = DB::table('users')
->whereExists(function (Builder $query) {
$query->select(DB::raw(1))
->from('orders')
->whereColumn('orders.user_id', 'users.id');
})
->get();
Alternatively, you may provide a query object to the whereExists method
instead of a closure:
1$orders = DB::table('orders')
2 ->select(DB::raw(1))
3 ->whereColumn('orders.user_id', 'users.id');
4
5$users = DB::table('users')
6 ->whereExists($orders)
7 ->get();
$orders = DB::table('orders')
->select(DB::raw(1))
->whereColumn('orders.user_id', 'users.id');
$users = DB::table('users')
->whereExists($orders)
->get();
Both of the examples above will produce the following SQL:
1select * from users
2where exists (
3 select 1
4 from orders
5 where orders.user_id = users.id
6)
select * from users
where exists (
select 1
from orders
where orders.user_id = users.id
)
Subquery Where Clauses
Sometimes you may need to construct a "where" clause that compares the results
of a subquery to a given value. You may accomplish this by passing a closure
and a value to the where method. For example, the following query will
retrieve all users who have a recent "membership" of a given type;
1use App\Models\User;
2use Illuminate\Database\Query\Builder;
3
4$users = User::where(function (Builder $query) {
5 $query->select('type')
6 ->from('membership')
7 ->whereColumn('membership.user_id', 'users.id')
8 ->orderByDesc('membership.start_date')
9 ->limit(1);
10}, 'Pro')->get();
use App\Models\User;
use Illuminate\Database\Query\Builder;
$users = User::where(function (Builder $query) {
$query->select('type')
->from('membership')
->whereColumn('membership.user_id', 'users.id')
->orderByDesc('membership.start_date')
->limit(1);
}, 'Pro')->get();
Or, you may need to construct a "where" clause that compares a column to the
results of a subquery. You may accomplish this by passing a column, operator,
and closure to the where method. For example, the following query will
retrieve all income records where the amount is less than average;
1use App\Models\Income;
2use Illuminate\Database\Query\Builder;
3
4$incomes = Income::where('amount', '<', function (Builder $query) {
5 $query->selectRaw('avg(i.amount)')->from('incomes as i');
6})->get();
use App\Models\Income;
use Illuminate\Database\Query\Builder;
$incomes = Income::where('amount', '<', function (Builder $query) {
$query->selectRaw('avg(i.amount)')->from('incomes as i');
})->get();
Full Text Where Clauses
Full text where clauses are currently supported by MariaDB, MySQL, and PostgreSQL.
The whereFullText and orWhereFullText methods may be used to add full text
"where" clauses to a query for columns that have full text
indexes. These methods will be
transformed into the appropriate SQL for the underlying database system by
Laravel. For example, a MATCH AGAINST clause will be generated for
applications utilizing MariaDB or MySQL:
1$users = DB::table('users')
2 ->whereFullText('bio', 'web developer')
3 ->get();
$users = DB::table('users')
->whereFullText('bio', 'web developer')
->get();
Ordering, Grouping, Limit and Offset
Ordering
The orderBy Method
The orderBy method allows you to sort the results of the query by a given
column. The first argument accepted by the orderBy method should be the
column you wish to sort by, while the second argument determines the direction
of the sort and may be either asc or desc:
1$users = DB::table('users')
2 ->orderBy('name', 'desc')
3 ->get();
$users = DB::table('users')
->orderBy('name', 'desc')
->get();
To sort by multiple columns, you may simply invoke orderBy as many times as
necessary:
1$users = DB::table('users')
2 ->orderBy('name', 'desc')
3 ->orderBy('email', 'asc')
4 ->get();
$users = DB::table('users')
->orderBy('name', 'desc')
->orderBy('email', 'asc')
->get();
The sort direction is optional, and is ascending by default. If you want to
sort in descending order, you can specify the second parameter for the
orderBy method, or just use orderByDesc:
1$users = DB::table('users')
2 ->orderByDesc('verified_at')
3 ->get();
$users = DB::table('users')
->orderByDesc('verified_at')
->get();
Finally, using the -> operator, the results can be sorted by a value within
a JSON column:
1$corporations = DB::table('corporations')
2 ->where('country', 'US')
3 ->orderBy('location->state')
4 ->get();
$corporations = DB::table('corporations')
->where('country', 'US')
->orderBy('location->state')
->get();
The latest and oldest Methods
The latest and oldest methods allow you to easily order results by date.
By default, the result will be ordered by the table's created_at column. Or,
you may pass the column name that you wish to sort by:
1$user = DB::table('users')
2 ->latest()
3 ->first();
$user = DB::table('users')
->latest()
->first();
Random Ordering
The inRandomOrder method may be used to sort the query results randomly. For
example, you may use this method to fetch a random user:
1$randomUser = DB::table('users')
2 ->inRandomOrder()
3 ->first();
$randomUser = DB::table('users')
->inRandomOrder()
->first();
Removing Existing Orderings
The reorder method removes all of the "order by" clauses that have
previously been applied to the query:
1$query = DB::table('users')->orderBy('name');
2
3$unorderedUsers = $query->reorder()->get();
$query = DB::table('users')->orderBy('name');
$unorderedUsers = $query->reorder()->get();
You may pass a column and direction when calling the reorder method in order
to remove all existing "order by" clauses and apply an entirely new order to
the query:
1$query = DB::table('users')->orderBy('name');
2
3$usersOrderedByEmail = $query->reorder('email', 'desc')->get();
$query = DB::table('users')->orderBy('name');
$usersOrderedByEmail = $query->reorder('email', 'desc')->get();
For convenience, you may use the reorderDesc method to reorder the query
results in descending order:
1$query = DB::table('users')->orderBy('name');
2
3$usersOrderedByEmail = $query->reorderDesc('email')->get();
$query = DB::table('users')->orderBy('name');
$usersOrderedByEmail = $query->reorderDesc('email')->get();
Grouping
The groupBy and having Methods
As you might expect, the groupBy and having methods may be used to group
the query results. The having method's signature is similar to that of the
where method:
1$users = DB::table('users')
2 ->groupBy('account_id')
3 ->having('account_id', '>', 100)
4 ->get();
$users = DB::table('users')
->groupBy('account_id')
->having('account_id', '>', 100)
->get();
You can use the havingBetween method to filter the results within a given
range:
1$report = DB::table('orders')
2 ->selectRaw('count(id) as number_of_orders, customer_id')
3 ->groupBy('customer_id')
4 ->havingBetween('number_of_orders', [5, 15])
5 ->get();
$report = DB::table('orders')
->selectRaw('count(id) as number_of_orders, customer_id')
->groupBy('customer_id')
->havingBetween('number_of_orders', [5, 15])
->get();
You may pass multiple arguments to the groupBy method to group by multiple
columns:
1$users = DB::table('users')
2 ->groupBy('first_name', 'status')
3 ->having('account_id', '>', 100)
4 ->get();
$users = DB::table('users')
->groupBy('first_name', 'status')
->having('account_id', '>', 100)
->get();
To build more advanced having statements, see the havingRaw method.
Limit and Offset
You may use the limit and offset methods to limit the number of results
returned from the query or to skip a given number of results in the query:
1$users = DB::table('users')
2 ->offset(10)
3 ->limit(5)
4 ->get();
$users = DB::table('users')
->offset(10)
->limit(5)
->get();
Conditional Clauses
Sometimes you may want certain query clauses to apply to a query based on
another condition. For instance, you may only want to apply a where
statement if a given input value is present on the incoming HTTP request. You
may accomplish this using the when method:
1$role = $request->input('role');
2
3$users = DB::table('users')
4 ->when($role, function (Builder $query, string $role) {
5 $query->where('role_id', $role);
6 })
7 ->get();
$role = $request->input('role');
$users = DB::table('users')
->when($role, function (Builder $query, string $role) {
$query->where('role_id', $role);
})
->get();
The when method only executes the given closure when the first argument is
true. If the first argument is false, the closure will not be executed.
So, in the example above, the closure given to the when method will only be
invoked if the role field is present on the incoming request and evaluates
to true.
You may pass another closure as the third argument to the when method. This
closure will only execute if the first argument evaluates as false. To
illustrate how this feature may be used, we will use it to configure the
default ordering of a query:
1$sortByVotes = $request->boolean('sort_by_votes');
2
3$users = DB::table('users')
4 ->when($sortByVotes, function (Builder $query, bool $sortByVotes) {
5 $query->orderBy('votes');
6 }, function (Builder $query) {
7 $query->orderBy('name');
8 })
9 ->get();
$sortByVotes = $request->boolean('sort_by_votes');
$users = DB::table('users')
->when($sortByVotes, function (Builder $query, bool $sortByVotes) {
$query->orderBy('votes');
}, function (Builder $query) {
$query->orderBy('name');
})
->get();
Insert Statements
The query builder also provides an insert method that may be used to insert
records into the database table. The insert method accepts an array of
column names and values:
1DB::table('users')->insert([
2 'email' => '[[email protected]](/cdn-cgi/l/email-protection)',
3 'votes' => 0
4]);
DB::table('users')->insert([
'email' => '[[email protected]](/cdn-cgi/l/email-protection)',
'votes' => 0
]);
You may insert several records at once by passing an array of arrays. Each array represents a record that should be inserted into the table:
1DB::table('users')->insert([
2 ['email' => '[[email protected]](/cdn-cgi/l/email-protection)', 'votes' => 0],
3 ['email' => '[[email protected]](/cdn-cgi/l/email-protection)', 'votes' => 0],
4]);
DB::table('users')->insert([
['email' => '[[email protected]](/cdn-cgi/l/email-protection)', 'votes' => 0],
['email' => '[[email protected]](/cdn-cgi/l/email-protection)', 'votes' => 0],
]);
The insertOrIgnore method will ignore errors while inserting records into
the database. When using this method, you should be aware that duplicate
record errors will be ignored and other types of errors may also be ignored
depending on the database engine. For example, insertOrIgnore will [bypass
MySQL's strict mode](https://dev.mysql.com/doc/refman/en/sql-mode.html#ignore-
effect-on-execution):
1DB::table('users')->insertOrIgnore([
2 ['id' => 1, 'email' => '[[email protected]](/cdn-cgi/l/email-protection)'],
3 ['id' => 2, 'email' => '[[email protected]](/cdn-cgi/l/email-protection)'],
4]);
DB::table('users')->insertOrIgnore([
['id' => 1, 'email' => '[[email protected]](/cdn-cgi/l/email-protection)'],
['id' => 2, 'email' => '[[email protected]](/cdn-cgi/l/email-protection)'],
]);
The insertUsing method will insert new records into the table while using a
subquery to determine the data that should be inserted:
1DB::table('pruned_users')->insertUsing([
2 'id', 'name', 'email', 'email_verified_at'
3], DB::table('users')->select(
4 'id', 'name', 'email', 'email_verified_at'
5)->where('updated_at', '<=', now()->subMonth()));
DB::table('pruned_users')->insertUsing([
'id', 'name', 'email', 'email_verified_at'
], DB::table('users')->select(
'id', 'name', 'email', 'email_verified_at'
)->where('updated_at', '<=', now()->subMonth()));
Auto-Incrementing IDs
If the table has an auto-incrementing id, use the insertGetId method to
insert a record and then retrieve the ID:
1$id = DB::table('users')->insertGetId(
2 ['email' => '[[email protected]](/cdn-cgi/l/email-protection)', 'votes' => 0]
3);
$id = DB::table('users')->insertGetId(
['email' => '[[email protected]](/cdn-cgi/l/email-protection)', 'votes' => 0]
);
When using PostgreSQL the insertGetId method expects the auto-incrementing
column to be named id. If you would like to retrieve the ID from a different
"sequence", you may pass the column name as the second parameter to the
insertGetId method.
Upserts
The upsert method will insert records that do not exist and update the
records that already exist with new values that you may specify. The method's
first argument consists of the values to insert or update, while the second
argument lists the column(s) that uniquely identify records within the
associated table. The method's third and final argument is an array of columns
that should be updated if a matching record already exists in the database:
1DB::table('flights')->upsert(
2 [
3 ['departure' => 'Oakland', 'destination' => 'San Diego', 'price' => 99],
4 ['departure' => 'Chicago', 'destination' => 'New York', 'price' => 150]
5 ],
6 ['departure', 'destination'],
7 ['price']
8);
DB::table('flights')->upsert(
[
['departure' => 'Oakland', 'destination' => 'San Diego', 'price' => 99],
['departure' => 'Chicago', 'destination' => 'New York', 'price' => 150]
],
['departure', 'destination'],
['price']
);
In the example above, Laravel will attempt to insert two records. If a record
already exists with the same departure and destination column values,
Laravel will update that record's price column.
All databases except SQL Server require the columns in the second argument of
the upsert method to have a "primary" or "unique" index. In addition, the
MariaDB and MySQL database drivers ignore the second argument of the upsert
method and always use the "primary" and "unique" indexes of the table to
detect existing records.
Update Statements
In addition to inserting records into the database, the query builder can also
update existing records using the update method. The update method, like
the insert method, accepts an array of column and value pairs indicating the
columns to be updated. The update method returns the number of affected
rows. You may constrain the update query using where clauses:
1$affected = DB::table('users')
2 ->where('id', 1)
3 ->update(['votes' => 1]);
$affected = DB::table('users')
->where('id', 1)
->update(['votes' => 1]);
Update or Insert
Sometimes you may want to update an existing record in the database or create
it if no matching record exists. In this scenario, the updateOrInsert method
may be used. The updateOrInsert method accepts two arguments: an array of
conditions by which to find the record, and an array of column and value pairs
indicating the columns to be updated.
The updateOrInsert method will attempt to locate a matching database record
using the first argument's column and value pairs. If the record exists, it
will be updated with the values in the second argument. If the record cannot
be found, a new record will be inserted with the merged attributes of both
arguments:
1DB::table('users')
2 ->updateOrInsert(
3 ['email' => '[[email protected]](/cdn-cgi/l/email-protection)', 'name' => 'John'],
4 ['votes' => '2']
5 );
DB::table('users')
->updateOrInsert(
['email' => '[[email protected]](/cdn-cgi/l/email-protection)', 'name' => 'John'],
['votes' => '2']
);
You may provide a closure to the updateOrInsert method to customize the
attributes that are updated or inserted into the database based on the
existence of a matching record:
1DB::table('users')->updateOrInsert(
2 ['user_id' => $user_id],
3 fn ($exists) => $exists ? [
4 'name' => $data['name'],
5 'email' => $data['email'],
6 ] : [
7 'name' => $data['name'],
8 'email' => $data['email'],
9 'marketable' => true,
10 ],
11);
DB::table('users')->updateOrInsert(
['user_id' => $user_id],
fn ($exists) => $exists ? [
'name' => $data['name'],
'email' => $data['email'],
] : [
'name' => $data['name'],
'email' => $data['email'],
'marketable' => true,
],
);
Updating JSON Columns
When updating a JSON column, you should use -> syntax to update the
appropriate key in the JSON object. This operation is supported on MariaDB
10.3+, MySQL 5.7+, and PostgreSQL 9.5+:
1$affected = DB::table('users')
2 ->where('id', 1)
3 ->update(['options->enabled' => true]);
$affected = DB::table('users')
->where('id', 1)
->update(['options->enabled' => true]);
Increment and Decrement
The query builder also provides convenient methods for incrementing or decrementing the value of a given column. Both of these methods accept at least one argument: the column to modify. A second argument may be provided to specify the amount by which the column should be incremented or decremented:
1DB::table('users')->increment('votes');
2
3DB::table('users')->increment('votes', 5);
4
5DB::table('users')->decrement('votes');
6
7DB::table('users')->decrement('votes', 5);
DB::table('users')->increment('votes');
DB::table('users')->increment('votes', 5);
DB::table('users')->decrement('votes');
DB::table('users')->decrement('votes', 5);
If needed, you may also specify additional columns to update during the increment or decrement operation:
1DB::table('users')->increment('votes', 1, ['name' => 'John']);
DB::table('users')->increment('votes', 1, ['name' => 'John']);
In addition, you may increment or decrement multiple columns at once using the
incrementEach and decrementEach methods:
1DB::table('users')->incrementEach([
2 'votes' => 5,
3 'balance' => 100,
4]);
DB::table('users')->incrementEach([
'votes' => 5,
'balance' => 100,
]);
Delete Statements
The query builder's delete method may be used to delete records from the
table. The delete method returns the number of affected rows. You may
constrain delete statements by adding "where" clauses before calling the
delete method:
1$deleted = DB::table('users')->delete();
2
3$deleted = DB::table('users')->where('votes', '>', 100)->delete();
$deleted = DB::table('users')->delete();
$deleted = DB::table('users')->where('votes', '>', 100)->delete();
Pessimistic Locking
The query builder also includes a few functions to help you achieve
"pessimistic locking" when executing your select statements. To execute a
statement with a "shared lock", you may call the sharedLock method. A shared
lock prevents the selected rows from being modified until your transaction is
committed:
1DB::table('users')
2 ->where('votes', '>', 100)
3 ->sharedLock()
4 ->get();
DB::table('users')
->where('votes', '>', 100)
->sharedLock()
->get();
Alternatively, you may use the lockForUpdate method. A "for update" lock
prevents the selected records from being modified or from being selected with
another shared lock:
1DB::table('users')
2 ->where('votes', '>', 100)
3 ->lockForUpdate()
4 ->get();
DB::table('users')
->where('votes', '>', 100)
->lockForUpdate()
->get();
While not obligatory, it is recommended to wrap pessimistic locks within a transaction. This ensures that the data retrieved remains unaltered in the database until the entire operation completes. In case of a failure, the transaction will roll back any changes and release the locks automatically:
1DB::transaction(function () {
2 $sender = DB::table('users')
3 ->lockForUpdate()
4 ->find(1);
5
6 $receiver = DB::table('users')
7 ->lockForUpdate()
8 ->find(2);
9
10 if ($sender->balance < 100) {
11 throw new RuntimeException('Balance too low.');
12 }
13
14 DB::table('users')
15 ->where('id', $sender->id)
16 ->update([
17 'balance' => $sender->balance - 100
18 ]);
19
20 DB::table('users')
21 ->where('id', $receiver->id)
22 ->update([
23 'balance' => $receiver->balance + 100
24 ]);
25});
DB::transaction(function () {
$sender = DB::table('users')
->lockForUpdate()
->find(1);
$receiver = DB::table('users')
->lockForUpdate()
->find(2);
if ($sender->balance < 100) {
throw new RuntimeException('Balance too low.');
}
DB::table('users')
->where('id', $sender->id)
->update([
'balance' => $sender->balance - 100
]);
DB::table('users')
->where('id', $receiver->id)
->update([
'balance' => $receiver->balance + 100
]);
});
Reusable Query Components
If you have repeated query logic throughout your application, you may extract
the logic into reusable objects using the query builder's tap and pipe
methods. Imagine you have these two different queries in your application:
1use Illuminate\Database\Query\Builder;
2use Illuminate\Support\Facades\DB;
3
4$destination = $request->query('destination');
5
6DB::table('flights')
7 ->when($destination, function (Builder $query, string $destination) {
8 $query->where('destination', $destination);
9 })
10 ->orderByDesc('price')
11 ->get();
12
13// ...
14
15$destination = $request->query('destination');
16
17DB::table('flights')
18 ->when($destination, function (Builder $query, string $destination) {
19 $query->where('destination', $destination);
20 })
21 ->where('user', $request->user()->id)
22 ->orderBy('destination')
23 ->get();
use Illuminate\Database\Query\Builder;
use Illuminate\Support\Facades\DB;
$destination = $request->query('destination');
DB::table('flights')
->when($destination, function (Builder $query, string $destination) {
$query->where('destination', $destination);
})
->orderByDesc('price')
->get();
// ...
$destination = $request->query('destination');
DB::table('flights')
->when($destination, function (Builder $query, string $destination) {
$query->where('destination', $destination);
})
->where('user', $request->user()->id)
->orderBy('destination')
->get();
You may like to extract the destination filtering that is common between the queries into a reusable object:
1<?php
2
3namespace App\Scopes;
4
5use Illuminate\Database\Query\Builder;
6
7class DestinationFilter
8{
9 public function __construct(
10 private ?string $destination,
11 ) {
12 //
13 }
14
15 public function __invoke(Builder $query): void
16 {
17 $query->when($this->destination, function (Builder $query) {
18 $query->where('destination', $this->destination);
19 });
20 }
21}
<?php
namespace App\Scopes;
use Illuminate\Database\Query\Builder;
class DestinationFilter
{
public function __construct(
private ?string $destination,
) {
//
}
public function __invoke(Builder $query): void
{
$query->when($this->destination, function (Builder $query) {
$query->where('destination', $this->destination);
});
}
}
Then, you can use the query builder's tap method to apply the object's logic
to the query:
1use App\Scopes\DestinationFilter;
2use Illuminate\Database\Query\Builder;
3use Illuminate\Support\Facades\DB;
4
5DB::table('flights')
6 ->when($destination, function (Builder $query, string $destination) {
7 $query->where('destination', $destination);
8 })
9 ->tap(new DestinationFilter($destination))
10 ->orderByDesc('price')
11 ->get();
12
13// ...
14
15DB::table('flights')
16 ->when($destination, function (Builder $query, string $destination) {
17 $query->where('destination', $destination);
18 })
19 ->tap(new DestinationFilter($destination))
20 ->where('user', $request->user()->id)
21 ->orderBy('destination')
22 ->get();
use App\Scopes\DestinationFilter;
use Illuminate\Database\Query\Builder;
use Illuminate\Support\Facades\DB;
DB::table('flights')
->when($destination, function (Builder $query, string $destination) {
$query->where('destination', $destination);
})
->tap(new DestinationFilter($destination))
->orderByDesc('price')
->get();
// ...
DB::table('flights')
->when($destination, function (Builder $query, string $destination) {
$query->where('destination', $destination);
})
->tap(new DestinationFilter($destination))
->where('user', $request->user()->id)
->orderBy('destination')
->get();
Query Pipes
The tap method will always return the query builder. If you would like to
extract an object that executes the query and returns another value, you may
use the pipe method instead.
Consider the following query object that contains shared
pagination logic used throughout an application.
Unlike the DestinationFilter, which applies query conditions to the query,
the Paginate object executes the query and returns a paginator instance:
1<?php
2
3namespace App\Scopes;
4
5use Illuminate\Contracts\Pagination\LengthAwarePaginator;
6use Illuminate\Database\Query\Builder;
7
8class Paginate
9{
10 public function __construct(
11 private string $sortBy = 'timestamp',
12 private string $sortDirection = 'desc',
13 private int $perPage = 25,
14 ) {
15 //
16 }
17
18 public function __invoke(Builder $query): LengthAwarePaginator
19 {
20 return $query->orderBy($this->sortBy, $this->sortDirection)
21 ->paginate($this->perPage, pageName: 'p');
22 }
23}
<?php
namespace App\Scopes;
use Illuminate\Contracts\Pagination\LengthAwarePaginator;
use Illuminate\Database\Query\Builder;
class Paginate
{
public function __construct(
private string $sortBy = 'timestamp',
private string $sortDirection = 'desc',
private int $perPage = 25,
) {
//
}
public function __invoke(Builder $query): LengthAwarePaginator
{
return $query->orderBy($this->sortBy, $this->sortDirection)
->paginate($this->perPage, pageName: 'p');
}
}
Using the query builder's pipe method, we can leverage this object to apply
our shared pagination logic:
1$flights = DB::table('flights')
2 ->tap(new DestinationFilter($destination))
3 ->pipe(new Paginate);
$flights = DB::table('flights')
->tap(new DestinationFilter($destination))
->pipe(new Paginate);
Debugging
You may use the dd and dump methods while building a query to dump the
current query bindings and SQL. The dd method will display the debug
information and then stop executing the request. The dump method will
display the debug information but allow the request to continue executing:
1DB::table('users')->where('votes', '>', 100)->dd();
2
3DB::table('users')->where('votes', '>', 100)->dump();
DB::table('users')->where('votes', '>', 100)->dd();
DB::table('users')->where('votes', '>', 100)->dump();
The dumpRawSql and ddRawSql methods may be invoked on a query to dump the
query's SQL with all parameter bindings properly substituted:
1DB::table('users')->where('votes', '>', 100)->dumpRawSql();
2
3DB::table('users')->where('votes', '>', 100)->ddRawSql();
DB::table('users')->where('votes', '>', 100)->dumpRawSql();
DB::table('users')->where('votes', '>', 100)->ddRawSql();
