示例1: doDeleteAll

*
* @param ConnectionInterface $con the connection to use
* @return int The number of affected rows (if supported by underlying database driver).
*/
public function doDeleteAll(ConnectionInterface $con = null)

}

// for more than one table or we could emulating ON DELETE CASCADE, etc.
