Wouldn't this: $id = mysql_insert_id(); $query = "UPDATE tablename SET id=" . ($id + 1); $result = mysql_query($query); Be a little simpler. But like I said, I'm confused over the need for this in the first place, seeing as how an "auto_incremented" primary key is self-descriptive. or are you saving this somewhere else in the DB?

Is there any trick about how to make it work? You'll need to insert a value into the table first, then you can do: $query = "UPDATE tablename SET id=LAST_INSERT_ID(id+1)"; $result = mysql_query($query); $id = mysql_insert_id(); This is in the mysql docs somewhere... -- Postgresql & php tutorials http://www.designmagick.com/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
