Script to alter Identity, Identity Seed, Identity Increment

Hi all
I need some Help in creating a SQL Script which I can Run direct on MS SQL
2000 Server.
Of existing tables I want to change the:
- Identity
- Identity Seed
- Identity Increment
I already tried something with ALTER TABLE, but I guess I did something
wrong, did not work sofar.
Would be glad if someone could give me an example of how to do this.
Thanks for the help
Cheers

1) What do you mean "change indentity"? You can drop the column defined as
an IDENTITY property
2)DBCC CHECKIDENT
3) DROP column and re-create with a new Increment

You can change the identity seed with dbcc checkident (you can see
more details in BOL). I don't know of any supported way to modify
the identity increment.

For Table X, the Collumn Name with the Primary Key, has Identity set to No
For this Collumn I want to Set the Identity to:Yes, with Identity Seed = 0
and Identity Increment = 1.
Because I have to do this more then once for several Tables, I do not want
to do this manually but through a Script.
The thing is: do not have a clue how to do it.

You cannot do that
CREATE TABLE Test (c INT NOT NULL)
INSERT INTO Test VALUES (1)
INSERT INTO Test VALUES (2)
--Want to add an IDENTITY Property
ALTER TABLE Test ADD c1 INT NOT NULL IDENTITY(1,1)
GO
ALTER TABLE Test DROP COLUMN c
GO
sp_rename 'Test.c1','c','column'
GO
SELECT * FROM Test
DROP TABLE Test
