OK, I thought you were implying it would be very slow if there were lots of fields. FWIW, there's a very easy way to get the structure and the list of fields in SQL Server Management Studio. Just right click on the table and select Script table as | Create to or Select to. So I managed to adjust your code in a few minutes.

Is there any way to specify what number an identity field starts generating at?
