20.4.41 mysql_real_query()

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

20.4.41.1 Description

Executes the SQL query pointed to by query, which should be a string length bytes long. The query must consist of a single SQL statement. You should not add a terminating semicolon (`;') or g to the statement.

You must use mysql_real_query() rather than mysql_query() for requêtesthat contain binary data, since binary data may contain the `0' character. In addition, mysql_real_query() is faster than mysql_query() since it does not call strlen() on the query string.

20.4.41.2 Return values

Zero if the query was successful. Non-zero if an error occurred.
