11.8 mysql_stmt_errno()

unsigned int mysql_stmt_errno(MYSQL_STMT *stmt)

Description

For the statement specified by stmt, mysql_stmt_errno() returns the error code for the most recently invoked statement API function that can succeed or fail. A return value of zero means that no error occurred. Client error message numbers are listed in the MySQL errmsg.h header file. Server error message numbers are listed in mysqld_error.h. Errors also are listed at Error Messages and Common Problems.

If the failed statement API function was mysql_stmt_close(), do not call or mysql_stmt_errno() to obtain error information because mysql_stmt_close() makes the statement handler invalid. Call mysql_errno() instead.

Return Values

An error code value. Zero if no error occurred.

Errors

None.
