    We are using the timestamp datatype feature to notify users when records change. So when something is updated we go to the parent and update it. If I had a statement like below where the ID is the PrimaryKey and updated it to itself to change the timestamp would it want to reindex the clustered key?

    Update Table1

    Set Id = Id

    Where Id = @Idpassedin

    Should I use a non-indexed field so that I improve performance?

    No... it should be ok.

    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.
