laravel db with count code example

Example 1: select sum in laravel

Sometime for such queries you need to disable the strict check
 So inside config/database.php and inside mysql, 
 Set 'strict' => false,

->select('user_id', DB::raw('SUM(points) as total_points'))

Example 2: laravel wher in

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