GROUP_CONCAT with different SEPARATOR in Laravel Example

Whenever, you need to use GROUP_CONCAT with differente separator(I mean default separator is ',', But you want to change '@','#','&' etc as you want). then you have to use use SEPARATOR keyword in GROUP_CONCAT(). If you are working on laravel then you have to also use DB::raw() for write GROUP_CONCAT() inside the this function.

So, Basically how to change seprator in group_concat(), In following example i change ',' separator into '@'.you can use the following example how to use in laravel 6, laravel 7, laravel 8, laravel 9 and laravel 10 versions.

Example:

<?php
  
namespace App\Http\Controllers;
   
use Illuminate\Http\Request;
use App\Models\Item;
use DB;
  
class DemoController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index(Request $request)
    {
        $items = Item::select(
                        "items.id",
                        "items.name",
                        DB::raw("(GROUP_CONCAT(items_city.name SEPARATOR '@')) as `cities`"))
                    ->leftjoin("items_city","items_city.item_id","=","items.id")
                    ->groupBy('items.id')
                    ->get();
