Unique record number ?
I am defining a table for staff members. In Access I would have used "autonumber" to use as a key. Is there an option like this in SQL? Will I have to manually code a way for each record to be unique?

Thanks

You can use the int (Identity) or UniqueIdentifier data type.

Can I define the uniquenumber in two different tables and build the relationship between the two tables based on that field?
