This would have been a good question and easy to get right if the schemaname had been spelt "Sales" instead of "SALES". However, I happened to remember that the database database collation for AdventureWorks2008R2 is Case Sensitive. Or at least that's what it is when installed out of the box on my laptop. My server default collation is NOT case sensitive, so it wasn't picking up case sensitivity from my server default, it's in AdventureWorks as supplied by MS. So I answered "neither" instead of "rank", because both queries will fail with an invalid oject name error.

Apparently the spelling was a mistake, since that was not the "correct" answer. Not at all an error I would expect to see in one of your questions, Ron! I can't see how the queries can have been tested.
