Don't try to give them a random number, instead use a table with a primary key that is AUTO_INCREMENT. Then you just insert the record, and afterwards SELECT LAST_INSERT_ID(); to retrieve the id for the record created.
With random numbers, you're going to have more collisions when you add more records.

I can do it in the application layer (php) but just wondering if there is an easier way in the database layer. Thanks Ray * for example, when registering a person for a contest, I want to give them a unique, random identifier. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql?unsub=gto...@ffn.com The information contained in this transmission may contain privileged and confidential information.
