Unique ID

Recommended Posts

Hi,
Im trying to create a form that submits customer details to a database. The input part all works okay. I want each customer to have a unique sequential ID. in the DB at the mo I have 001,002,003,005,006 so I would want it to use 004 or 007 if 004 has been used.

Any Ideas on how I should go about this. I tried google but Im unsure on the search terms to use.

Cheers,

Andy
