    Or CROSS APPLY VALUES:

    -- sample data

    ;WITH gennum (tollnum, n1, n2, n3) AS (

    SELECT 800123, 1234, 1235, 1236 UNION ALL

    SELECT 999123, 9876, 9875, 9874

    )

    -- solution

    SELECT g.tollnum, d.code

    FROM gennum g

    CROSS APPLY (VALUES (n1), (n2), (n3)) d (code)

    Didn't know this one 🙂

    One more for the "bag" 🙂

    Nice.

    And after all the work I've done trying to get the word out too! [face-to-palm]

    Thanks for the plug Chris!
