PHP & Laravel | 在 GroupBy 之后使用 OrderBy

Question

This is my Php code

 $elements= DB::table('transactions')
  ->select('product_id', DB::raw('count(*) as total'))
  ->groupBy('product_id')
  ->get();

I want to apply an orderby and a limit('5') on count

Any orientation? Thank you.

Answer 1

add orderBy()..and take()

 $elements= DB::table('transactions')
  ->select('product_id', DB::raw('count(*) as total'))
  ->groupBy('product_id')
  ->orderBy('your_column')
  ->take(5)
  ->get();
