mysql_read_query_result

mysql_read_query_result reads the result of a statement previously sent with mysql_send_query, and must be called once for each successful mysql_send_query call.

Syntax

my_bool mysql_read_query_result(MYSQL * mysql);

Parameter

• mysql - a mysql handle, which was previously allocated by mysql_init() or mysql_real_connect().

Description

mysql_read_query_result() reads the result of a SQL statement executed with mysql_send_query(). If the SQL statement returned a result set, it must be freed before the next call to mysql_read_query_result() is made. This is similar to how results from mysql_query() must be processed before another call can be made.

Return Value

Returns zero on success, otherwise non-zero.
