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 usersSQL Drop View Query
DROP VIEW IF EXISTS `view_data`;Let’s create migration with views.
php artisan make:migration create_viewUpdate 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"
