I answered the wrong question.:crying: "Objective: Update all the M's to F and all F's to M. " and the result of statement 4 will not be that objective. And as the question was phrased so confusingly I thought perhaps it meant did it succeed in meeting its objective. Clearly not, but then perhaps I ought to read questions more carefully!

Yes, it did mean that and yes, statement 4 will succeed in doing that. If you don't believe that, try running it and see that it does.

Oops again.:w00t:This time I didn't even read the objective correctly! for some reason I thought it was just to set all values of Gender to 'M'. Apologies to the question setter.

Very good question. Also good way to show how values can be swapped. 🙂

I, too caught on the (success OR failure), the collation-dependent field name, and the missed shorthand opportunity CASE Gender WHEN...

You can't answer a question of the type 'A or B? ' with TRUE or FALSE. Yet these are the only answers we can give.

Clearly illogical.

The other column was defined using the IDENTITY property. See http://msdn.microsoft.com/en-us/library/ms186775.aspx.
