I am trying to alter an identity column using dynamic sql, but get the following error:

Msg 156, Level 15, State 1, Line 2
Incorrect syntax near the keyword 'IDENTITY'.

ALTER TABLE crdm.Header_20090111
ALTER COLUMN TransactionID BIGINT IDENTITY (3,1)

Is this not possible?

Thanks

I think you may have to remove the identity and re-add it to alter it

But the code you posted is non-dynamic
You cant alter the column to have a identity property

Hi all

Thank you for your replies. SOrry for not replying sooner, but I had gone home.

To answer some of your questions:

Example code not dynamic:
That was just for ease of posting.

Why dynamic:
Long story, but I have to generate a DB scheme to emulate partitioning (with a different partition each day). Therefore, the code has to create the tables using template examples, and recreate all constraints, keys, etc, but using different names based on dates. Hope that makes sense???

THanks for the link, I think that concludes what Skorch said, I shall have to drop and recreate the column.

Thanks guys
