The tricky part is that, to get an error message, you must pass both the error code *and* the MySQL handle, while you can only specify a simple [error code -> error message] map without any other context information (like the MySQL handle). At last, I had to deprecate the message() method of the corresponding error_category subclass.<br /><br />I wonder how can this issue be solved?lianchenghttp://www.blogger.com/profile/13567239080256716067noreply@blogger.com
