Database: Query Builder

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.

[!WARNING]
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}
 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}

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 $user->name;
7}
1use Illuminate\Support\Facades\DB;
2 
3$users = DB::table('users')->get();
4 
5foreach ($users as $user) {
6    echo $user->name;
7}

[!NOTE]
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 $user->email;
1$user = DB::table('users')->where('name', 'John')->first();
2 
3return $user->email;

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$email = DB::table('users')->where('name', 'John')->value('email');
1$email = DB::table('users')->where('name', 'John')->value('email');

To retrieve a single row by its id column value, use the find method:

1$user = DB::table('users')->find(3);
1$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 $title;
7}
1use Illuminate\Support\Facades\DB;
2 
3$titles = DB::table('users')->pluck('title');
4 
5foreach ($titles as $title) {
6    echo $title;
7}

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 $title;
5}
1$titles = DB::table('users')->pluck('title', 'name');
2 
3foreach ($titles as $name => $title) {
4    echo $title;
5}

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});
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});

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});
1DB::table('users')->orderBy('id')->chunk(100, function (Collection $users) {
2    // Process the records...
3 
4    return false;
5});

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    });
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    });

[!WARNING]
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});
1use Illuminate\Support\Facades\DB;
2 
3DB::table('users')->orderBy('id')->lazy()->each(function (object $user) {
4    // ...
5});

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    });
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    });

[!WARNING]
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');
1use Illuminate\Support\Facades\DB;
2 
3$users = DB::table('users')->count();
4 
5$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$price = DB::table('orders')
2                ->where('finalized', 1)
3                ->avg('price');
1$price = DB::table('orders')
2                ->where('finalized', 1)
3                ->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}
1if (DB::table('orders')->where('finalized', 1)->exists()) {
2    // ...
3}
4 
5if (DB::table('orders')->where('finalized', 1)->doesntExist()) {
6    // ...
7}

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$users = DB::table('users')
4            ->select('name', 'email as user_email')
5            ->get();
1use Illuminate\Support\Facades\DB;
2 
3$users = DB::table('users')
4            ->select('name', 'email as user_email')
5            ->get();

The distinct method allows you to force the query to return distinct results:

1$users = DB::table('users')->distinct()->get();
1$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 = $query->addSelect('age')->get();
1$query = DB::table('users')->select('name');
2 
3$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$users = DB::table('users')
2             ->select(DB::raw('count(*) as user_count, status'))
3             ->where('status', '<>', 1)
4             ->groupBy('status')
5             ->get();
1$users = DB::table('users')
2             ->select(DB::raw('count(*) as user_count, status'))
3             ->where('status', '<>', 1)
4             ->groupBy('status')
5             ->get();

[!WARNING]
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 can not 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$orders = DB::table('orders')
2                ->selectRaw('price * ? as price_with_tax', [1.0825])
3                ->get();
1$orders = DB::table('orders')
2                ->selectRaw('price * ? as price_with_tax', [1.0825])
3                ->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$orders = DB::table('orders')
2                ->whereRaw('price > IF(state = "TX", ?, 100)', [200])
3                ->get();
1$orders = DB::table('orders')
2                ->whereRaw('price > IF(state = "TX", ?, 100)', [200])
3                ->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$orders = DB::table('orders')
2                ->select('department', DB::raw('SUM(price) as total_sales'))
3                ->groupBy('department')
4                ->havingRaw('SUM(price) > ?', [2500])
5                ->get();
1$orders = DB::table('orders')
2                ->select('department', DB::raw('SUM(price) as total_sales'))
3                ->groupBy('department')
4                ->havingRaw('SUM(price) > ?', [2500])
5                ->get();

orderByRaw

The orderByRaw method may be used to provide a raw string as the value of the "order by" clause:

1$orders = DB::table('orders')
2                ->orderByRaw('updated_at - created_at DESC')
3                ->get();
1$orders = DB::table('orders')
2                ->orderByRaw('updated_at - created_at DESC')
3                ->get();

groupByRaw

The groupByRaw method may be used to provide a raw string as the value of the group by clause:

1$orders = DB::table('orders')
2                ->select('city', 'state')
3                ->groupByRaw('city, state')
4                ->get();
1$orders = DB::table('orders')
2                ->select('city', 'state')
3                ->groupByRaw('city, state')
4                ->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$users = DB::table('users')
4            ->join('contacts', 'users.id', '=', 'contacts.user_id')
5            ->join('orders', 'users.id', '=', 'orders.user_id')
6            ->select('users.*', 'contacts.phone', 'orders.price')
7            ->get();
1use Illuminate\Support\Facades\DB;
2 
3$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();

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();
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();

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$sizes = DB::table('sizes')
2            ->crossJoin('colors')
3            ->get();
1$sizes = DB::table('sizes')
2            ->crossJoin('colors')
3            ->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();
1DB::table('users')
2        ->join('contacts', function (JoinClause $join) {
3            $join->on('users.id', '=', 'contacts.user_id')->orOn(/* ... */);
4        })
5        ->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();
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();

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            $join->on('users.id', '=', 'latest_posts.user_id');
9        })->get();
1$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();

Lateral Joins

[!WARNING]
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($latestPosts, 'latest_posts')
9            ->get();
1$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();

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($first)
9            ->get();
1use Illuminate\Support\Facades\DB;
2 
3$first = DB::table('users')
4            ->whereNull('first_name');
5 
6$users = DB::table('users')
7            ->whereNull('last_name')
8            ->union($first)
9            ->get();

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$users = DB::table('users')
2                ->where('votes', '=', 100)
3                ->where('age', '>', 35)
4                ->get();
1$users = DB::table('users')
2                ->where('votes', '=', 100)
3                ->where('age', '>', 35)
4                ->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$users = DB::table('users')->where('votes', 100)->get();
1$users = DB::table('users')->where('votes', 100)->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$users = DB::table('users')
10                ->where('name', 'like', 'T%')
11                ->get();
 1$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();

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$users = DB::table('users')->where([
2    ['status', '=', '1'],
3    ['subscribed', '<>', '1'],
4])->get();
1$users = DB::table('users')->where([
2    ['status', '=', '1'],
3    ['subscribed', '<>', '1'],
4])->get();

[!WARNING]
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.

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$users = DB::table('users')
2                    ->where('votes', '>', 100)
3                    ->orWhere('name', 'John')
4                    ->get();
1$users = DB::table('users')
2                    ->where('votes', '>', 100)
3                    ->orWhere('name', 'John')
4                    ->get();

If you need to group an "or" condition within parentheses, you may pass a closure as the first argument to the orWhere method:

1$users = DB::table('users')
2            ->where('votes', '>', 100)
3            ->orWhere(function (Builder $query) {
4                $query->where('name', 'Abigail')
5                      ->where('votes', '>', 50);
6            })
7            ->get();
1$users = DB::table('users')
2            ->where('votes', '>', 100)
3            ->orWhere(function (Builder $query) {
4                $query->where('name', 'Abigail')
5                      ->where('votes', '>', 50);
6            })
7            ->get();

The example above will produce the following SQL:

1select * from users where votes > 100 or (name = 'Abigail' and votes > 50)
1select * from users where votes > 100 or (name = 'Abigail' and votes > 50)

[!WARNING]
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                    $query->where('clearance', true)
4                          ->orWhere('price', '<', 10);
5                })
6                ->get();
1$products = DB::table('products')
2                ->whereNot(function (Builder $query) {
3                    $query->where('clearance', true)
4                          ->orWhere('price', '<', 10);
5                })
6                ->get();

Where Any / All 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$users = DB::table('users')
2            ->where('active', true)
3            ->whereAny([
4                'name',
5                'email',
6                'phone',
7            ], 'LIKE', 'Example%')
8            ->get();
1$users = DB::table('users')
2            ->where('active', true)
3            ->whereAny([
4                'name',
5                'email',
6                'phone',
7            ], 'LIKE', 'Example%')
8            ->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)
1SELECT *
2FROM users
3WHERE active = true AND (
4    name LIKE 'Example%' OR
5    email LIKE 'Example%' OR
6    phone LIKE 'Example%'
7)

Similarly, the whereAll method may be used to retrieve records where all of the given columns match a given constraint:

1$posts = DB::table('posts')
2            ->where('published', true)
3            ->whereAll([
4                'title',
5                'content',
6            ], 'LIKE', '%Laravel%')
7            ->get();
1$posts = DB::table('posts')
2            ->where('published', true)
3            ->whereAll([
4                'title',
5                'content',
6            ], 'LIKE', '%Laravel%')
7            ->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)
1SELECT *
2FROM posts
3WHERE published = true AND (
4    title LIKE '%Laravel%' AND
5    content LIKE '%Laravel%'
6)

JSON Where Clauses

Laravel also supports querying JSON column types on databases that provide support for JSON column types. Currently, this includes MySQL 8.0+, PostgreSQL 12.0+, SQL Server 2017+, and SQLite 3.39.0+ (with the JSON1 extension). To query a JSON column, use the -> operator:

1$users = DB::table('users')
2                ->where('preferences->dining->meal', 'salad')
3                ->get();
1$users = DB::table('users')
2                ->where('preferences->dining->meal', 'salad')
3                ->get();

You may use whereJsonContains to query JSON arrays:

1$users = DB::table('users')
2                ->whereJsonContains('options->languages', 'en')
3                ->get();
1$users = DB::table('users')
2                ->whereJsonContains('options->languages', 'en')
3                ->get();

If your application uses the MySQL or PostgreSQL databases, you may pass an array of values to the whereJsonContains method:

1$users = DB::table('users')
2                ->whereJsonContains('options->languages', ['en', 'de'])
3                ->get();
1$users = DB::table('users')
2                ->whereJsonContains('options->languages', ['en', 'de'])
3                ->get();

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();
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();

Additional Where Clauses

whereBetween / orWhereBetween

The whereBetween method verifies that a column's value is between two values:

1$users = DB::table('users')
2           ->whereBetween('votes', [1, 100])
3           ->get();
1$users = DB::table('users')
2           ->whereBetween('votes', [1, 100])
3           ->get();

whereNotBetween / orWhereNotBetween

The whereNotBetween method verifies that a column's value lies outside of two values:

1$users = DB::table('users')
2                    ->whereNotBetween('votes', [1, 100])
3                    ->get();
1$users = DB::table('users')
2                    ->whereNotBetween('votes', [1, 100])
3                    ->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$patients = DB::table('patients')
2                       ->whereBetweenColumns('weight', ['minimum_allowed_weight', 'maximum_allowed_weight'])
3                       ->get();
1$patients = DB::table('patients')
2                       ->whereBetweenColumns('weight', ['minimum_allowed_weight', 'maximum_allowed_weight'])
3                       ->get();

The whereNotBetweenColumns method verifies that a column's value lies outside the two values of two columns in the same table row:

1$patients = DB::table('patients')
2                       ->whereNotBetweenColumns('weight', ['minimum_allowed_weight', 'maximum_allowed_weight'])
3                       ->get();
1$patients = DB::table('patients')
2                       ->whereNotBetweenColumns('weight', ['minimum_allowed_weight', 'maximum_allowed_weight'])
3                       ->get();

whereIn / whereNotIn / orWhereIn / orWhereNotIn

The whereIn method verifies that a given column's value is contained within the given array:

1$users = DB::table('users')
2                    ->whereIn('id', [1, 2, 3])
3                    ->get();
1$users = DB::table('users')
2                    ->whereIn('id', [1, 2, 3])
3                    ->get();

The whereNotIn method verifies that the given column's value is not contained in the given array:

1$users = DB::table('users')
2                    ->whereNotIn('id', [1, 2, 3])
3                    ->get();
1$users = DB::table('users')
2                    ->whereNotIn('id', [1, 2, 3])
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', $activeUsers)
5                    ->get();
1$activeUsers = DB::table('users')->select('id')->where('is_active', 1);
2 
3$users = DB::table('comments')
4                    ->whereIn('user_id', $activeUsers)
5                    ->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)
1select * from comments where user_id in (
2    select id
3    from users
4    where is_active = 1
5)

[!WARNING]
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.

whereNull / whereNotNull / orWhereNull / orWhereNotNull

The whereNull method verifies that the value of the given column is NULL:

1$users = DB::table('users')
2                ->whereNull('updated_at')
3                ->get();
1$users = DB::table('users')
2                ->whereNull('updated_at')
3                ->get();

The whereNotNull method verifies that the column's value is not NULL:

1$users = DB::table('users')
2                ->whereNotNull('updated_at')
3                ->get();
1$users = DB::table('users')
2                ->whereNotNull('updated_at')
3                ->get();

whereDate / whereMonth / whereDay / whereYear / whereTime

The whereDate method may be used to compare a column's value against a date:

1$users = DB::table('users')
2                ->whereDate('created_at', '2016-12-31')
3                ->get();
1$users = DB::table('users')
2                ->whereDate('created_at', '2016-12-31')
3                ->get();

The whereMonth method may be used to compare a column's value against a specific month:

1$users = DB::table('users')
2                ->whereMonth('created_at', '12')
3                ->get();
1$users = DB::table('users')
2                ->whereMonth('created_at', '12')
3                ->get();

The whereDay method may be used to compare a column's value against a specific day of the month:

1$users = DB::table('users')
2                ->whereDay('created_at', '31')
3                ->get();
1$users = DB::table('users')
2                ->whereDay('created_at', '31')
3                ->get();

The whereYear method may be used to compare a column's value against a specific year:

1$users = DB::table('users')
2                ->whereYear('created_at', '2016')
3                ->get();
1$users = DB::table('users')
2                ->whereYear('created_at', '2016')
3                ->get();

The whereTime method may be used to compare a column's value against a specific time:

1$users = DB::table('users')
2                ->whereTime('created_at', '=', '11:20:45')
3                ->get();
1$users = DB::table('users')
2                ->whereTime('created_at', '=', '11:20:45')
3                ->get();

whereColumn / orWhereColumn

The whereColumn method may be used to verify that two columns are equal:

1$users = DB::table('users')
2                ->whereColumn('first_name', 'last_name')
3                ->get();
1$users = DB::table('users')
2                ->whereColumn('first_name', 'last_name')
3                ->get();

You may also pass a comparison operator to the whereColumn method:

1$users = DB::table('users')
2                ->whereColumn('updated_at', '>', 'created_at')
3                ->get();
1$users = DB::table('users')
2                ->whereColumn('updated_at', '>', 'created_at')
3                ->get();

You may also pass an array of column comparisons to the whereColumn method. These conditions will be joined using the and operator:

1$users = DB::table('users')
2                ->whereColumn([
3                    ['first_name', '=', 'last_name'],
4                    ['updated_at', '>', 'created_at'],
5                ])->get();
1$users = DB::table('users')
2                ->whereColumn([
3                    ['first_name', '=', 'last_name'],
4                    ['updated_at', '>', 'created_at'],
5                ])->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               $query->where('votes', '>', 100)
5                     ->orWhere('title', '=', 'Admin');
6           })
7           ->get();
1$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();

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')
1select * from users where name = 'John' and (votes > 100 or title = 'Admin')

[!WARNING]
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               $query->select(DB::raw(1))
4                     ->from('orders')
5                     ->whereColumn('orders.user_id', 'users.id');
6           })
7           ->get();
1$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();

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($orders)
7                    ->get();
1$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();

Both of the examples above will produce the following SQL:

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    $query->select('type')
 6        ->from('membership')
 7        ->whereColumn('membership.user_id', 'users.id')
 8        ->orderByDesc('membership.start_date')
 9        ->limit(1);
10}, 'Pro')->get();
 1use App\Models\User;
 2use Illuminate\Database\Query\Builder;
 3 
 4$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();

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    $query->selectRaw('avg(i.amount)')->from('incomes as i');
6})->get();
1use App\Models\Income;
2use Illuminate\Database\Query\Builder;
3 
4$incomes = Income::where('amount', '<', function (Builder $query) {
5    $query->selectRaw('avg(i.amount)')->from('incomes as i');
6})->get();

Full Text Where Clauses

[!WARNING]
Full text where clauses are currently supported by 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 MySQL:

1$users = DB::table('users')
2           ->whereFullText('bio', 'web developer')
3           ->get();
1$users = DB::table('users')
2           ->whereFullText('bio', 'web developer')
3           ->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$users = DB::table('users')
2                ->orderBy('name', 'desc')
3                ->get();
1$users = DB::table('users')
2                ->orderBy('name', 'desc')
3                ->get();

To sort by multiple columns, you may simply invoke orderBy as many times as necessary:

1$users = DB::table('users')
2                ->orderBy('name', 'desc')
3                ->orderBy('email', 'asc')
4                ->get();
1$users = DB::table('users')
2                ->orderBy('name', 'desc')
3                ->orderBy('email', 'asc')
4                ->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$user = DB::table('users')
2                ->latest()
3                ->first();
1$user = DB::table('users')
2                ->latest()
3                ->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$randomUser = DB::table('users')
2                ->inRandomOrder()
3                ->first();
1$randomUser = DB::table('users')
2                ->inRandomOrder()
3                ->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 = $query->reorder()->get();
1$query = DB::table('users')->orderBy('name');
2 
3$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 = $query->reorder('email', 'desc')->get();
1$query = DB::table('users')->orderBy('name');
2 
3$usersOrderedByEmail = $query->reorder('email', 'desc')->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$users = DB::table('users')
2                ->groupBy('account_id')
3                ->having('account_id', '>', 100)
4                ->get();
1$users = DB::table('users')
2                ->groupBy('account_id')
3                ->having('account_id', '>', 100)
4                ->get();

You can use the havingBetween method to filter the results within a given range:

1$report = DB::table('orders')
2                ->selectRaw('count(id) as number_of_orders, customer_id')
3                ->groupBy('customer_id')
4                ->havingBetween('number_of_orders', [5, 15])
5                ->get();
1$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();

You may pass multiple arguments to the groupBy method to group by multiple columns:

1$users = DB::table('users')
2                ->groupBy('first_name', 'status')
3                ->having('account_id', '>', 100)
4                ->get();
1$users = DB::table('users')
2                ->groupBy('first_name', 'status')
3                ->having('account_id', '>', 100)
4                ->get();

To build more advanced having statements, see the havingRaw method.

Limit and Offset

The skip and take Methods

You may use the skip and take methods to limit the number of results returned from the query or to skip a given number of results in the query:

1$users = DB::table('users')->skip(10)->take(5)->get();
1$users = DB::table('users')->skip(10)->take(5)->get();

Alternatively, you may use the limit and offset methods. These methods are functionally equivalent to the take and skip methods, respectively:

1$users = DB::table('users')
2                ->offset(10)
3                ->limit(5)
4                ->get();
1$users = DB::table('users')
2                ->offset(10)
3                ->limit(5)
4                ->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 = $request->string('role');
2 
3$users = DB::table('users')
4                ->when($role, function (Builder $query, string $role) {
5                    $query->where('role_id', $role);
6                })
7                ->get();
1$role = $request->string('role');
2 
3$users = DB::table('users')
4                ->when($role, function (Builder $query, string $role) {
5                    $query->where('role_id', $role);
6                })
7                ->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                    $query->orderBy('name');
8                })
9                ->get();
1$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();

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]',
3    'votes' => 0
4]);
1DB::table('users')->insert([
2    'email' => '[email protected]',
3    'votes' => 0
4]);

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]', 'votes' => 0],
3    ['email' => '[email protected]', 'votes' => 0],
4]);
1DB::table('users')->insert([
2    ['email' => '[email protected]', 'votes' => 0],
3    ['email' => '[email protected]', 'votes' => 0],
4]);

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:

1DB::table('users')->insertOrIgnore([
2    ['id' => 1, 'email' => '[email protected]'],
3    ['id' => 2, 'email' => '[email protected]'],
4]);
1DB::table('users')->insertOrIgnore([
2    ['id' => 1, 'email' => '[email protected]'],
3    ['id' => 2, 'email' => '[email protected]'],
4]);

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()));
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()));

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$id = DB::table('users')->insertGetId(
2    ['email' => '[email protected]', 'votes' => 0]
3);
1$id = DB::table('users')->insertGetId(
2    ['email' => '[email protected]', 'votes' => 0]
3);

[!WARNING]
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);
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);

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.

[!WARNING]
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 MySQL database driver ignores the second argument of the upsert method and always uses 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$affected = DB::table('users')
2              ->where('id', 1)
3              ->update(['votes' => 1]);
1$affected = DB::table('users')
2              ->where('id', 1)
3              ->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 can not be found, a new record will be inserted with the merged attributes of both arguments:

1DB::table('users')
2    ->updateOrInsert(
3        ['email' => '[email protected]', 'name' => 'John'],
4        ['votes' => '2']
5    );
1DB::table('users')
2    ->updateOrInsert(
3        ['email' => '[email protected]', 'name' => 'John'],
4        ['votes' => '2']
5    );

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 MySQL 5.7+ and PostgreSQL 9.5+:

1$affected = DB::table('users')
2              ->where('id', 1)
3              ->update(['options->enabled' => true]);
1$affected = DB::table('users')
2              ->where('id', 1)
3              ->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);
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);

If needed, you may also specify additional columns to update during the increment or decrement operation:

1DB::table('users')->increment('votes', 1, ['name' => 'John']);
1DB::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]);
1DB::table('users')->incrementEach([
2    'votes' => 5,
3    'balance' => 100,
4]);

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();
1$deleted = DB::table('users')->delete();
2 
3$deleted = DB::table('users')->where('votes', '>', 100)->delete();

If you wish to truncate an entire table, which will remove all records from the table and reset the auto-incrementing ID to zero, you may use the truncate method:

1DB::table('users')->truncate();
1DB::table('users')->truncate();

Table Truncation and PostgreSQL

When truncating a PostgreSQL database, the CASCADE behavior will be applied. This means that all foreign key related records in other tables will be deleted as well.

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();
1DB::table('users')
2        ->where('votes', '>', 100)
3        ->sharedLock()
4        ->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();
1DB::table('users')
2        ->where('votes', '>', 100)
3        ->lockForUpdate()
4        ->get();

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();
1DB::table('users')->where('votes', '>', 100)->dd();
2 
3DB::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();
1DB::table('users')->where('votes', '>', 100)->dumpRawSql();
2 
3DB::table('users')->where('votes', '>', 100)->ddRawSql();
