It seems like an error in MySQL to us.
The maximum length of a CHAR or VARCHAR is 255 characters. If you create a string longer than that, it can't be CHAR or VARCHAR. MySQL uses the next smallest string type large enough to hold the result: BLOB. (At least, that's what I suspect is happening.) --------------------------------------------------------------------- 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?
