@@IDENTITY is potentially a BAD thing! SELECT SCOPE_IDENTITY() is a
better choice since @@identity could return the wrong value if there are
triggers on the table.

Example:

Here's a table explaining the difference:

SELECT @@IDENTITY <- Session Scope
SELECT IDENT_CURRENT('tablename') <- Table scope
SELECT SCOPE_IDENTITY <- statement scope
