The added method, query_rows, allows the retrieval of rows from a database without the need for a callback function, it fetches the rows and returns 3 arguments as show below. ``` lua local success, rows, err = dbh:query_rows(sql) ``` This function performs better with large number of rows. Test results below 50k rows returned. dbh:query(sql, callback) - 0.335949 seconds dbh:query_rows(sql) - 0.253178 seconds
