No. For MyISAM tables, it will change on DELETE/UPDATES. For other table types I don't know. Aside from that, you should not rely it anyhow, because this is a implementation detail and it may change without notice according to the SQL specification. Regarding mysqldump, have a look at an earlier post from me: http://lists.mysql.com/cgi-ez/ezmlm-cgi?1:msn:10037:lcmmfflncinfjoipdpmc Bye, Benjamin. -- [EMAIL PROTECTED] --------------------------------------------------------------------- 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?
