    Is most simple:
       DECLARE @Birthday date = '1994/12/10'

        SELECT (CAST(CONVERT(VARCHAR(8), GETDATE(), 112) AS INT) - CAST(CONVERT(VARCHAR(8), @Birthday, 112) AS INT)) / 10000 AS Age

    I've not checked some of the possibilities nor have I checked it for performance  but THAT IS mighty interesting especially for how it correctly determines ages when a Leap Day is involved.

    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.
