http://www.mysql.com/doc/U/P/UPDATE.html MySQL does not support sub-queries, such as the one you are attempting here. (the "FROM" on..) You could try INSERT...SELECT http://www.mysql.com/doc/I/N/INSERT_SELECT.html or REPLACE...SELECT http://www.mysql.com/doc/R/E/REPLACE.html The REPLACE is probably what you're looking for, but be careful, "REPLACE works exactly like INSERT, except that if an old record in the table has the same value as a new record on a unique index, the old record is deleted before the new record is inserted. " HTH! Jay "We are all apparently 'net' literate, why don't we use it to get the information we need? After all, isn't that what a Google search is all about?" --------------------------------------------------------------------- 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?
