mysql_stmt_free_result()

Last Updated：2023-07-26 02:37:19 Updated

You can call the mysql_stmt_free_result() function to free the memory associated with the result set produced by the execution of a prepared statement.

Syntax

my_bool
mysql_stmt_free_result(MYSQL_STMT *stmt)

Return values

0 is returned for an execution success, and a non-zero value is returned if an error occurred.

Notes

If a cursor is open for the statement, mysql_stmt_free_result() closes it.
