OK. The problem is I don't want the next "highest" number. There are gaps in the UID sequence. I need to find the next UNUSED number in the sequence which is rarely the "highest" number.

If its an autoincrement, the next highest number will be assigned by the db. There is no need to query the db to find it. Simply insert the record and leave the id field out of the insert statement. bastien >From: "NIPP, SCOTT V (SBCSI)" <sn4265@xxxxxxx> >To: <php-db@xxxxxxxxxxxxx> >Subject: Auto-increment questions... >Date: Tue, 5 Oct 2004 11:58:41 -0500 > > I am working on a database application for Unix user accounts. >I want to be able to have a system that will provide me the next >available numeric user ID.
