How do i make a autonumber field in my table!

Hi
im new to ms sql server, having previously used mysql. How do i make a auto number field? What datatype shall i use for it? like autonumber for mysql.

Ive tried setting my primary key field touniqueidentifier data type but then i still need to manually add a guid key in there. i want it so it automatically generates a unique key everytime i add a new row. is this possible?!

hope someone can help!
thanks
SQL Server uses IDENTITY for the auto number, in SQL Server it is a property to the column it is not a column, there are many IDENTITY in SQL Server what you need is the property. The Uniqueidentifier is different that uses a GUID which is a 16bytes Binary data type in SQL Server while IDENTITY is INT. Run a search for SET IDENTITY property in SQL Server BOL (books online). Hope this helps.|||thanks didnt know it was that easy!
