How to Use MySQL View in Laravel 9?

In this blog post, you can explore the concept of MySQL views and explain how to effectively integrate them into Laravel applications.

SQL Create View Query

CREATE VIEW view_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_data`;

 Let’s create migration with views.

php artisan make:migration create_view

Update Migration File:

<?php

  

use Illuminate\Database\Migrations\Migration;

use Illuminate\Database\Schema\Blueprint;

use Illuminate\Support\Facades\Schema;

  

class CreateView 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 <<

            CREATE VIEW view_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;

    }

   

    /**

     * Reverse the migrations.

     *

     * @return void

     */

    private function dropView(): string

    {

        return <<

            DROP VIEW IF EXISTS `view_data`;

            SQL;

    }

}

now we will create model as below:

app/ViewData.php

<?php

  

namespace App;

  

use Illuminate\Database\Eloquent\Model;

 

class ViewUserData extends Model

{

    public $table = "view_data";

}

Now we can use it as below on the controller file:

<?php

  

namespace App\Http\Controllers;

  

use Illuminate\Http\Request;

use App\ViewData;

  

class UserController extends Controller

{

    /**

     * Display a listing of the resource.

     *

     * @return \Illuminate\Http\Response

     */

    public function index()

    {

        $users = ViewData::select("*")

                        ->get()

                        ->toArray();

          

        dd($users);

    }

}

you can see output:-

array:20 [▼

  0 => array:5 [▼

    "id" => 1

    "name" => "Roshan Kumar Jha"

    "email" => "roshan.cotocus@gmail.com"
