    I think there are accounting standads that say 4 d.p. should be used for money calculations.

    Well, that would depend on your country of operation, wouldn't it?

    Actually, MONEY is useful if only for documentation purposes. You could use decimal but why would you want to? Being an integer makes the type faster than decimal.

    DATETIME does...

    Yes, because MONEY is a precise data type with 4 decimal places. It's implemented as a 64-bit integer, scaled down by 10000. That and DATETIME must be the two lamest...

    I think the extra decimal digit is because if you multiply a number with 2 decimal places by a number with 1 decimal place, the result can have 3...

    Yes, a strange result. Try this:

    DECLARE @tmp1 FLOAT = 0.289;
    SELECT CONVERT(decimal(38,36),ROUND(@tmp1, 2)*100),
    CONVERT(decimal(38,36),ROUND(@tmp1, 2))*100

    Well, that's no more strange than any...

    Well, 29 would have been too easy, and the title of the QOTD hinted at the result not being quite the obvious. Casting to INT always truncates decimals, so it...

  • Reply To: Float Issues

    Good one!

    The problem is that casting to int always removes any decimals, and with the example, 0.289 is actually stored as a value which, when converted with the maximum number...

    Option 1 works only if you replace the {} with [] as follows:

    True, dat! So, we're down to the missing alternative of "None", I suppose...

    Option 1 may well work, but in this instance, it's renaming the wrong field so is wrong for the question posted.

    Option one should work, shouldn't it, since it sets the name of all the columns, but uses the old name...

    I thought I wouldn't touch this question until it's been reviewed, but I couldn't resist.

    Clearly, option 3 wouldn't work, since the original column name is "BillingAmount", and not "BillAmount". In...

    I'll defer answering until Steve has sorted this one out.

  • Reply To: The Default NULL

    Well, unfortunately, the documentation is a bit off. The bit about the session settings is correct, which matches what I wrote.

    The bit about the database settings is incorrect. The correct...

  • Reply To: The Default NULL

    Not to nit-pick, but the option is actually called ANSI_NULL_DFLT_OFF, so technically, all the answers are incorrect.

    However, the database option is called ANSI_NULL_DEFAULT, which can be set to OFF or...

  • Reply To: Printing Dates

    Looking at the available answers, the only logical response would be that it would fail, since all the other answers have both date and time that doesn't match the input...
