Question

I am having trouble implementing the group_by and having queries using Eloquent in Laravel.

Here is the scenario:

orders
 - id
 - qty

deliveries
 -         


        

Answer 1

Ended up switching to Laravel 4 and doing the ff which seemed to work.

Order::leftJoin('deliveries', 'orders.id', '=', 'deliveries.order_id')
 ->select(array('orders.*'), DB::raw('orders.qty - IFNULL(sum(deliveries.qty),0) AS balance')))
 ->groupBy('order_id')
 ->havingRaw('balance > 0')
 ->get();
