Very good question.Refreshed the basics.
I was not sure about middle two but sure about first two(7,7) and last two(14,80).
So objective approach which I developed from Engineering Entrance Exam worked and got the right answer ;-)

I thought the 4th one would be 8 at first, but since 7, 7, 8, 8, 14, 80 wasn't an option had to go by a process of elimination to find the right answer! Slightly odd behaviour from nchar() there, I learned something...

Slightly odd behaviour from nchar() there, I learned something...

Hmmm, not sure why you this is strange behaviour for nchar. It is fixed length, so any shorter length string put into it has to be padded. And if you then concatenate another string, it will of course go after the original string (which includes the padding). If you don't want the padding to be in there, use LTRIM() (or use nvarchar instead of nchar, obviously).

In my opinion, it is LEN() that has the strange behaviour here, because it returns the length of the padded version of the string instead of the length of the string itself. This almost caused me to give the wrong answer - but I recalled just in time the number of times I have already been bitten by this strange behaviour of LEN().


Thanks for a good question, Kenneth!
