SQL Apprentice Question
I'm creating a new SQL 2005 Express database and want to have a Customers
table. How do I auto-increment the CustomerID field? Programming in VB.Net

Let's get back to the basics of an RDBMS. Rows are not records; fields
are not columns; tables are not files; there is no sequential access or
ordering in an RDBMS.

What you want is a relational key that you can verify and validate.
Auto-incrementing has to do with the internal state of the hardware and
not the data model. This is why there are industry standard codes, why
websites use email addreses, etc.
