Laravel Migration Create Mysql View Example

This article will provide some of the most important example how to use mysql view in laravel. This post will give you simple example of laravel using mysql views. you will learn laravel eloquent mysql view. i would like to share with you laravel model mysql view. Let’s see bellow example how to call mysql view in laravel.

In this post, i will show you how to create mysql view using laravel migration and how to use mysql view with laravel eloquent model.

basically, we are using sql view because we don’t require to write long query on our database again and again. if you create simple view then you can easily get data from that view.

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 CreateUserdata 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_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;
    }
   
    /**
     * Reverse the migrations.
     *
     * @return void
     */
    private function dropView(): string
    {
        return <<
            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/ViewUserdata.php

<?php
  
namespace App;
  
use Illuminate\Database\Eloquent\Model;
 
class ViewUserdata extends Model
{
    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\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:203 [▼
  0 => array:5 [▼
    "id" => 1
    "name" => "Prof. Josiane Jast MD"
    "email" => "savanihd@gmail.com"
    "total_posts" => 3
    "total_comments" => 2
  ]
  1 => array:5 [▼
    "id" => 2
    "name" => "Mr. Donavon Beer"
    "email" => "yemmerich@example.net"
    "total_posts" => 0
    "total_comments" => 0
  ]
  2 => array:5 [▼
    "id" => 3
    "name" => "Judy Watsica"
    "email" => "gutmann.christian@example.org"
    "total_posts" => 0
    "total_comments" => 0

I hope it can help you…
