CODE EXAMPLE FOR PHP

Laravel Query: orderBy not working with groupBy (with a joined table)

$receivedmessages = DB::table('messages')
    ->join('users', 'users.id', '=', 'messages.sender_id')
    ->select('messages.*', 'users.username')
    ->whereRaw('messages.id IN (SELECT MAX(messages.id) FROM messages GROUP BY receiver_id, sender_id)')
    ->where('receiver_id', Auth::user()->id)
    ->orderByDesc('messages.created_at')
    ->get();
