如何将许多语句mysql转换为laravel雄辩？

主要是原始查询：

DB::table('item_details')->selectRaw('GROUP_CONCAt(...) INTO @sql')->get();DB::statement('SET @sql = CONCAt(...)');DB::statement('PREPARE stmt FROM @sql');DB::statement('EXECUTE stmt');DB::statement('DEALLOCATE PREPARE stmt');

尝试这个：

DB::table('item_details')->selectRaw('GROUP_CONCAt(...) INTO @sql')->get();$sql = DB::selectOne('select @sql')->{'@sql'};ItemDetails::select('item_number', DB::raw('SUM(quantity) as total_quantity'))    ->selectRaw($sql)    ->groupBy('item_number')    ->get();
