Hi, I would like to use AUTO_INCTRMENT on a column but I would like it start from zero. Example:- ID | Colour ------------ 0 | black 1 | white 2 | red etc... >From my understanding of the manual, if insert a NULL into an AUTO_INCREMENT column, the next number in the sequence is inserted. Therefore which is start off as one. Unless I make the column as TINYINT UNSIGNED NOT NULL DEFAULT 0, then is not incrementing. Any comment or help will be appreciated. annalise [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?
