Index autoincrement for Microsoft SQL Server 2008 R2

Question

I created a new table in SQL Server 2008 R2, and i would like that the index is on autoincrement. How to do that? There is no identity data type; i selected int

Answer 1

If your table definition is like this,

....,
@id int,
....

change it to,

....
@id int identity(1,1),
....

This will create an identity column which starts id with 1 and keeps increasing it by one(i.e. step) as each record in the table is inserted.
