    Hi,

    You can try below solution

    delete T1

    from MyTable T1, MyTable T2

    where T1.dupField = T2.dupField

    and T1.uniqueField > T2.uniqueField

    Finally... a different idea than the rest. However, that uses a Triangular Join. Read the article at the following URL for why that might not be such a good idea, Amit.

    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.
