Executes the TRUNCATE query.

Return value

Return value is dependent on whether the executed SQL statement is a TRUNCATE or a DELETE. TRUNCATE is DDL and no information on affected rows is available. DELETE is DML and will return the number of affected rows. In general, do not rely on the value returned by this method in calling code.
