Group by multiple columns in Laravel

Question

How to GROUP BY multiple column in Laravel? I tried this code:

$routes = DB::table(\'route\')
    ->groupBy(\'rte_origin\')
    ->groupBy(         


        

Answer 1

Put the select before the groupBy and the arguments in brackets.

$routes = DB::table('route')
    ->select(['column_1', 'column_2'])
    ->groupBy(['column_1', 'column_2'])
    ->get();
