The reason that it's not implemented in the JDBC driver, is that MySQL issues warnings on every single query, except it's called "Extra Info", and it's not always a warning. The overhead in parsing these messages (which happen to be different depending on the locale installed, complicating matters even further), has not been asked for by users of the driver, yet. In any case, what the server returns in the case of a real warning will not give you _any_ diagnostics on a warning, just that something happened (e.g. see http://www.mysql.com/doc/I/N/INSERT.html at the bottom of the page), so it's not helpful in diagnosing that data has changed. The protocol for MySQL 4.1 will have a way to retrieve only warnings, and hopefully a more descriptive warning message implementation. -Mark --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
