    It can matter whather you do the multiply or divide first.

    (12 / 3) * 2 will give a different answer to 12 / (3*2)

    Yes, but that's...

  • RE: Basic maths - operator precedence

    BODMAS says:

    B Brackets first

    O Orders (i.e. Powers and Square Roots, etc.)

    DM Division and Multiplication (left-to-right)

    AS Addition and Subtraction (left-to-right)

    It actually doesn't matter whether you do the...

  • RE: Type conversions and Nulls

    Excellent question and explanation - several issues covered in one go - thank you.

  • RE: Date Difference

    Nice 50/50 question that doesn't hurt the brain too much on the morning after Superbowl...:cool:

  • RE: Computed column

    Good simple question; I like the lower case int and the strangely placed comma to make people look twice before answering. 😉

  • RE: Data compression

    dinolg (1/30/2013)


    Everyone seems to mention BOL, but fails to mention a quote, or any kind of reference.

    The BOL reference is in the explanation.

    I thought it was pretty clear that the...

    This question would have been so much better if it had been based on a much lower number of rows that were included in the question (so that...

    sipas (1/25/2013)Personally I don't give two hoots if I get the answer right or not - as long as I learn something useful.

    I agree with that sentiment, however...

  • RE: Relational Model versus XML

    Sean Pearce (1/24/2013)


    Terrible question. To have to make such a fundamental architecture decision with a one sentence spec means this project will be doomed from the start.

    Which is why you...

    I knew I was going to get this one wrong since it was basically a opinion piece. Good discussion but not a great question.

  • RE: Relational Model versus XML

    @Nils Gustav:

    Not a good analogy because one option is only applicable under extremely unlikely circumstances (e.g. you cannot fly due to a medical condition but you have the time and...

    Hugo Kornelis (1/24/2013)
