Order By before Group By using Eloquent (Laravel)

Question

I have a \"messages\" table with the following columns

CREATE TABLE `messages` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `fromId` int(11) NOT NULL,
  `toId         


        

Answer 1

I found a way to do that! Basically, creating a subquery and running it before, so that results are ordered as expected and grouped after.

Here is the code:

$sub = Message::orderBy('createdAt','DESC');

$chats = DB::table(DB::raw("({$sub->toSql()}) as sub"))
    ->where('toId',$id)
    ->groupBy('fromId')
    ->get();
