Question

I have a sql query which inserts a lot of new rows in table and updates a lot of old rows.
Is there a way to determine all rows which where inserted?

Found this in a previous Stackoverflow article:
How to insert multiple records and get the identity value?

Below is by Andy Irving:

Use the ouput clause from 2005:

DECLARE @output TABLE (id int)

Insert into A (fname, lname)
OUTPUT inserted.ID INTO @output
SELECT fname, lname FROM B

select * from @output

now your table variable has the identity values of all the rows you insert.
