If there a way to use the INSERT > command and extract the new AUTO_INCREMENT all in one command? LAST_INSERT_ID() returns the last auto-incremented number for your database connection. Yes, this means that even if you execute this and someone else has auto-incremented the table in the meantime, you will still have your auto-incremented number (not the new, higher one). That is why this function is better than doing SELECT MAX() on that column. Erik ---- Erik Price Web Developer Temp Media Lab, H.H.
