In this case, I need to get the Field Name from the table :
this is my static model
  <?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\Facades\Schema;
class Act_admin extends Model
{
    static function showCust(){
        $query = DB::table("dummy_db.customer")->select("*")->paginate(10);
        $FieldNames = Schema::getColumnListing($query);
        dd($FieldNames);
      // return $data;
    }
}
and the result just:
[]
Thanks before.
