    First query has an extra ; before ORDER BY, just a comment.

    Thanks, fixed.

  • I can see how you view subjects as a general concept as separate from the instance of a subject. I have reworded to ask about classes.

    So... how do we get to answer the question again with the revised wording?

    Just don't answer in a hurry, wait a little. Have taken this QotD today. Have read it 3 times trying to understand what is the catch, why it costs 2 points. Gave up and marked option number 2. 🙂

    +1 ==> I have had the same reasoning but my most important surprise is to have given the good answer.

    I am regretting that tortuous way of thought. I have met this during the 4th question of an interview and I preferred to stop immediately, saying that I didn't want to work with with a person who is not able to be clear. But I got my revenge the year when this person asked a not understandable question on my favorite forum (SMO), I was too glad to reply him in a polite way that it is impossible to get a correct reply with a unclear question and he never got a full answer...
