Maybe that's the difference... I'm running SQL Sever 2000 Enterprise Edition with SP4. Just kidding... I get the same execution plans on an SP3a box as well. I don't know what the difference is because I havn't altered Northwind on either of mine either.

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.
If you think its expensive to hire a professional to do the job, wait until you hire an amateur. -- Red Adair

That assumes that the Column_Name field doesn't allow null values otherwise, I believe, if the value does happen to be null setting the @Param_Name to null won't "eliminate" it. Null is not equal to Null.
