Auto key generation

Hi,

Can any one tell me how can I create auto number (similar feature to MS Access) i.e. autmatic increament by 1 in MS SQL 2005 (without using any script)

make the column an identity

CREATE TABLE test(id INT IDENTITY, SomeOtherVAlue varchar(50))

INSERT test VALUES( 'A' )
INSERT test VALUES( 'B' )
INSERT test VALUES( 'C' )
INSERT test VALUES( 'D' )
INSERT test VALUES( 'E' )
INSERT test VALUES( 'F' )
GO

SELECT * FROM Test

id SomeOtherVAlue
-- --
1 A
2 B
3 C
4 D
5 E
6 F
