Following on from Jim Fosters comment about the "BEGIN TRANSACTION; INSERT INTO @Vendors VALUES (1, 'Wicked Widgets Inc.', 'A');ROLLBACK TRANSACTION" statement. I ticked this as not being valid. This is clearly not the intended outcome and although it produces no syntax or runtime errors it should fall under the "NOT valid statements" category.

I would let it slide if there wasn't an identical statement without the rollback transaction which i think is designed to emphasise the difference. The only difference between the two is the rollback transaction which is not valid and should really give the following error "Msg 3903, Level 16, State 1, Line 1. The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION."
