access：autonumber字段但不与主键并行

Question

I'm creating a customer help form (for reporting computer support)

After inserting a Customer in the database, a number should be generated like: WO: 00001

The number should be unique, because when the same Customer has another job, it should be for example: WO: 00012 assuming there were a few clients before him.

What should I do?

Answer 1

Just use an autonumber integer field. You can append the WO and add the leading zeros in your select or at render time.
