16   Parameters
17       • MYSQL_RES - a result set identifier returned by mysql_store_result(3)

19         depends on whether buffered or unbuffered result sets are being used.
20         For unbuffered result sets, mysql_num_rows() will not return the cor‐
21         rect  number  of  rows until all the rows in the result have been re‐
22         trieved.
