RE: [PHP] Inserting records in a particular way in MySQL

Miles, I never use auto increment. Not because of gaps, but in case I need to reload the table. They do have meaning if they are foreign keys to another table. - Larry -----Original Message----- From: Miles Thompson [mailto:milesthompson@ns.sympatico.ca] Sent: Sunday, February 16, 2003 1:14 PM To: Phillip S.

All this does is identify a record. If you did a SELECT and found a missing sequence number, what's to say that value would not be inserted by another user before your INSERT? If you have not set up the table with a MyISAM, MySQL will eventually use the missing numbers. These are only identifying tags, with no intrinsic meaning.
