    That will certainly work and if you don't have many rows, you probably won't notice, but REVERSE is comparatively very expensive... it would be computationally cheaper if you just used STUFF and LEN alone by a fair bit.

    SELECT STUFF(yourcolumn,LEN(yourcolumn-3),3,'GIF') which would probably be the fastest.

    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.
