  • Very Easy 🙂

  • Nice 'n' eazy.

  • None of the answers are correct when you take into account the names are with a capital and the answers are lower case, the question was to give all names from the table, answer 3 and 4 do this. Never was the question to give all names duplicates included. Question could be better worded.

  • Both choice 3 and 4 is correct.Because author does not say duplicate names are ok.:crazy:

    Good question, thanks Stuart

    That would depend on the case sensitivity / collation of the database you are working in.

    It was sparked by new dev here, who couldn't see the difference between any of the four possible answers :w00t:

    As the question and answer showed mixed cases, case insensitivity is implied, again something missed by our now ex dev.

  • The question said "every employee", that should be clear enough, one record per employee. If you DISTINCT, you get list of peoples names, not people.

  • Nice basic question

    I agree. There are no need to fuzz over the question being "worded badly" as erwin.oosterhoorn and vivekjamshedpur says..

    I cringe when I read this. A new dev who have no clue about boolean expressions. No wonder you name him/her "our now ex dev", because that's a steep hill, this one is trying to climb!

  • Thanks for the question.

    And here I was reading them thinking to myself that it must have been strange trying to come up with the wrong answers. Granted, we see a lot of stuff in our own systems and here, but for something so simple, it must have been weird. A nice, simple, unambiguous question, Stuart. Thanks.

    No, they aren't. He even bolded the word "all" in the question. Even without bolding it, it would have still meant the same thing.
