You're both wrong. You should test it, and see for yourselves that unless you're using the old and obsolete ISAM table format, auto_increment values are NEVER reused. This, of course, is true if the auto_increment is on the first part of an index, and you don't delete all rows in the table with a DELETE without a WHERE. //C sql -- Carl Troein - Círdan / Istari-PixelMagic - UIN 16353280 [EMAIL PROTECTED] | http://pixelmagic.dyndns.org/~cirdan/ Amiga user since '89, and damned proud of it too. --------------------------------------------------------------------- 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?
