I want to write a stored procedure in DTS.
Where the task is to dump Orders table from Northwind Database to a New Database and also i need to change the OrderID, starting from 15000 instead of 10248.

I created a table in the new database and inserted the table from Northwind to new database .But , when i am trying to update the OrderID, i get the following error:

Cannot update identity column 'OrderID'

If you're doing this in stored procedure, use

SET IDENTITY_INSERT ON before the update statement and put it back to off once update is done by
SET IDENTITY_INSERT OFF

if you're doing update in DTS by means of export then check option "Enable identity insert".

You cannot update an identity column, with or without SET IDENTITY_INSERT on.

You need to set the value as you load the table, not update it after it is loaded.




set identity_insert NewTable on

insert into NewTable (...col list...)
select
	ID = ID+SomeValue ,
	...col list ...
from
	OldTable

set identity_insert NewTable off
