    Heres how to calculate an age

    select CASE

    WHEN dateadd(year, datediff (year, d1, d2), d1) > d2

    THEN datediff (year, d1, d2) - 1

    ELSE datediff (year, d1, d2)

    END as Age

    I'll take a look at the rounding issue though...

    That's one of the simplest I've seen. Correctly handles the Feb 29 problem that most other's don't handle, too!

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
