I would to make a SUM in query with Laravel 5
Query Builder.
return DB::table('table1')->join('table2','table1.id','=','table2.id')
->where('table1.user_id','=',$userId)
->whereMonth('table2.date', '=', $month )
->whereYear('table2.date', '=', $year )->select('table2.*', DB::raw('SUM(table1.count) AS count_single'))->groupby('table2.id')->get();
but my problem is that I have a prefix table (xc_), and DB::raw return error
"Column not found: 1054 Unknown column 'table1.count' "
It is a problem with prefix table, because if I put:
$table_prefix = env('DB_TABLE_PREFIX', 'xc_');
DB::raw('SUM('.$table_prefix.'table1.count) AS count_single')
It work, so the problem is prefix, but I don't like this method, and so: there is a method for use DB::Raw without specifying prefix table?
