Instead of getting the current # out of the db, incrementing it, and then updating the field, try this: CREATE TABLE foo (clicks INT); INSERT INTO foo SET clicks=0; SELECT * FROM foo; UPDATE foo SET clicks=clicks+1; SELECT * FROM foo; UPDATE foo SET clicks=clicks+1; SELECT * FROM foo; UPDATE foo SET clicks=clicks+1; SELECT * FROM foo; DROP TABLE foo; You can increment 'columnname' with 'columnname+1'; that way, you don't need to get the current value first. -- denonymous www.coldcircuit.net --------------------------------------------------------------------- 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?
