int mysql_real_query(MYSQL *mysql, const char *stmt_str, unsigned long length)


Executes the SQL statement pointed to by stmt_str, which should be a string length bytes long. Normally, the string must consist of a single SQL statement and you should not add a terminating semicolon (“;”) or \g to the statement. If multiple-statement execution has been enabled, the string can contain several statements separated by semicolons. See Section 22.9.13, “C API Support for Multiple Statement Execution”.

mysql_query() cannot be used for statements that contain binary data; you must use mysql_real_query() instead. (Binary data may contain the “\0” character, which mysql_query() interprets as the end of the statement string.) In addition, mysql_real_query() is faster than mysql_query() because it does not call strlen() on the statement string.

If you want to know whether the statement should return a result set, you can use mysql_field_count() to check for this. See Section, “mysql_field_count().

Return Values

Zero if the statement was successful. Nonzero if an error occurred.
