laravel group by value code example

Example 1: laravel group by with where clause

$groupedSalesCampaign = Order::with('Campaign')
            ->where('isapproved','=','Y')
            ->groupBy('campaign_id')
            ->orderBy(DB::raw('COUNT(id)','desc'))
            ->get(array(DB::raw('COUNT(id) as totalsales'),'campaign_id'));

Example 2: groupby in laravel

You can use unique('field_name'); instead of groupBy('field_name');
/**
 * Show the application dashboard.
 *
 * @return \Illuminate\Http\Response
 */
public function index()
{
    $messages = Message::select("*")
                            ->where('receiver_id',$id)
                            ->orderBy('created_at', 'desc')
                            ->get()
                            ->unique('sender_id');
  
    dd($messages);
}
