Have you read about the bug with @@IDENTITY and SCOPE_IDENTITY():
https://connect.microsoft.com/SQLServer/feedback/details/328811/scope-identity-sometimes-returns-incorrect-value

If the comments are right, this bug isn’t fixed until version 2012 comes out this year.

hai yual,
You can use ‘OUTPUT Inserted.UID as Prim_Key’ inside the insert query.Then return the Prim_Key value.

inside the insert query…….Any other method?????

I’m having trouble figuring out how to gather multiple ids from an insert into from select. I need to create a new revision of an item and the item is multirelated to another table and that table is multi-related to other tables, I need to gather the new ids and relate them to the old ids so I can make sure all the relationships are connecting correctly. Doing it 1 at a time would work with a cursor but I’m trying avoid using a cursors. I would apriciate any help. Thank You

hi Pinal,
In the case of Uniqueidentifier ,returning empty from stored procedure while i am using @@IDENTITY or SCOPE_IDENTITY() for getting the primary key (which is unique identifier)of last inserted row.
Can you solve this problem?
Any other function available for retrieving the primary key value of last inserted row while using the uniqueidentifier type for primary key?

ALTER PROCEDURE [dbo].[REGISTER_USER]

insert into GUEST_DETAILS (User_id,Fname, Lname) values(@fk, @fname, @lname);
select SCOPE_IDENTITY();
select @@IDENTITY
end

— Insert statements for procedure here

END

Here I want to return the scope identity of both USER_INFO and GUEST_DETAIL tables at a time.

How is it possible by using the scope_identity() function.

There is no system function available for uniqueidentifier. You need to assign newid() value to a variable and use that variable to insert to a table. This is the only way you can keep tract of last uniqueidentifier

By: Gaurav Girdher

Gaurav Girdher — Mon, 11 Apr 2011 12:30:48 +0000

Hi Pinal,
Your article is just awesome.
I have a small query regarding the performance of the Three Clauses used above:
Can you please tell which one is better from performance point of view

@@IDENTITY / SCOPE_IDENTITY() / IDENT_CURRENT(‘tablename’)

Waiting for your reply.

Regards
Gaurav Girdher
