Good question.

I anticipate many people will go for the NULL answer.

Good question.
I anticipate many people will go for the NULL answer.

Yes they will. The concept is important, though. The presence of the row makes all the difference in the world. One might even argue the presence of rows is the start of learning to count. 😉

Made my guess, ran the code, got back NULL. Not an empty record set - NULL.

Made my guess, ran the code, got back NULL. Not an empty record set - NULL.

So, did I. Even though that's what I answered, that's not what I was expecting since the explanation made sense to me.

~~Can anyone explain why I would get something back?~~

Never mind. I see why. There are two select statements. The second one is doing a select on the variable @test-2 which is null. That's the one that is returning a null value.
