Pretty easy question, if you eliminate incorrect answers.

@b-2 is never used, so the first and the last answer were impossible.

I knew there wasn't any incorrect syntax with the aliases, so the second answer was also incorrect. So that leaves us only with the arrays of numbers.

However, as the B column always returns 1, it was pretty easy to deduce the correct answer.

Nonetheless, great question which incorporated various scenarios. Thanks.

Thank you for the question.

Had to think this one through because of the operators.

And the variable was just to mess with us? 😛

Nice question Carlo! My first thought was, "What am I supposed to learn from this question?" Then I dug in a little deeper. Got it right, but not as quickly as I might have. I still haven't learned to read the title for help.

I still have the "Look at the shiny object ..." reaction when I follow the link to the question.

I'm hoping by this afternoon I will have read the explanation enough times to understand it, because I sure as heck don't at this hour of the morning! 😉

Thanks for an interesting question. I got the right answer but not by thinking it all the way through so I learned something new - always a good way to start the morning!
