Now let's see example of how to use mysql view in laravel 8 application. In this tutorial, i will show you create mysql view in laravel 8 application. I’m going to show you about laravel migration create view. Here you will learn laravel migration make view. i explained simply step by step how to use mysql view in laravel. Let's see bellow example laravel using mysql views.
This tutorial will give you how to use mysql view in laravel 8. We will learn how to create mysql view in laravel 8.
In this example, we will create "view_user_data" view and i will get count posts and comments of that user. so we don't require to fire again and again same query on server. so let's simple example bellow:
Bellow my sql query for creating view and drop view:
SQL Create View Query
CREATE VIEW view_user_data AS
SELECT
users.id,
users.name,
users.email,
(SELECT count(*) FROM posts
WHERE posts.user_id = users.id
) AS total_posts,
(SELECT count(*) FROM comments
WHERE comments.user_id = users.id
) AS total_comments
FROM users
SQL Drop View Query
DROP VIEW IF EXISTS `view_user_data`;
Now we need to use this query on our live database with laravel migration. so let's create migration with views.
Create Migration:
php artisan make:migration create_user_view
Update Migration File:
<?php
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;
class CreateUserView extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
\DB::statement($this->createView());
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
\DB::statement($this->dropView());
}
/**
* Reverse the migrations.
*
* @return void
*/
private function createView(): string
{
return <<<SQL
CREATE VIEW view_user_data AS
SELECT
users.id,
users.name,
users.email,
(SELECT count(*) FROM posts
WHERE posts.user_id = users.id
) AS total_posts
FROM users
SQL;
}
/**
* Reverse the migrations.
*
* @return void
*/
private function dropView(): string
{
return <<<SQL
DROP VIEW IF EXISTS `view_user_data`;
SQL;
}
}
Now, we can run migration command:
php artisan migrate
We have created view, it's looks like as bellow:
now we will create model as bellow:
app/Models/ViewUserData.php
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class ViewUserData extends Model
{
use HasFactory;
public $table = "view_user_data";
}
Now we can use it as bellow on controller file:
Controller file code
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\ViewUserData;
class UserController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
$users = ViewUserData::select("*")
->get()
->toArray();
dd($users);
}
you can see output as bellow:
array:12 [?
0 => array:4 [?
"id" => 1
"name" => "Alayna Weimann"
"email" => "audra.waelchi@example.org"
"total_posts" => 2
]
1 => array:4 [?
"id" => 2
"name" => "Herman Mann"
"email" => "selena31@example.com"
"total_posts" => 1
]
2 => array:4 [?
"id" => 3
"name" => "Miss Greta Huels V"
"email" => "kshlerin.alta@example.com"
"total_posts" => 0
]
3 => array:4 [?
"id" => 4
"name" => "Mr. Jaeden Kunze MD"
"email" => "jast.derick@example.org"
"total_posts" => 0
]
4 => array:4 [?
"id" => 5
"name" => "Gerald Stoltenberg"
"email" => "bashirian.earl@example.net"
"total_posts" => 0
]
]
It will help you....
