UPDATE sequence_table SET sequence = LAST_INSERT_ID(sequence + 1) Further calls to LAST_INSERT_ID on the same connection will return the value "sequence + 1". It's connection specific, so multiple connections can update your sequence table without interfering with each other.
There's a great example of this in Paul DuBois' book "MySQL" from New Riders. --jeff ----- Original Message ----- From: "Allon Bendavid" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Monday, March 18, 2002 7:57 PM Subject: INSERT ...
