The only thing I don't like about this at first glance is there is no check to see if the data actually changed. So if I issue the statement...

UPDATE Users
SET user_name = user_name
WHERE user_id = 'Fred1234';



...then the code fragment supplied will say the column was updated, when in fact nothing changed.

I agree Matt. This is what I use in my triggers to see if a change has actually occurred.

IF EXISTS (SELECT *
FROM
INSERTED I JOIN DELETED D ON I.Key = D.Key
WHERE
I.Col <> D.Col)
