    Not sure which article you're referring to but the answer is "No... not for SELECT's". Even though a SORT won't show up on the execution plan, the only way to guarantee the order (seems like it's much better in 2k5 than 2k) is to use an order by on "N" in the Numbers or Tally table.

    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.
