Interesting, albeit megalomaniacal question 😀

Woww .... to many nested While loops 🙂

Nice question, as its reminded the nested loop depth. Thanks for sharing.

I wonder what Jeff Moden have to say about this ... :hehe:

You have a bug in your code here: SET @strend = @strend + ' SET @intloopCounter=@intloopCounter+1 END '

and the variable should be @intLoopCounter, case letters depends. With your code on any SQL place it throws errors.

In Theory, theory and practice are the same...In practice, they are not.

Due to an error in the variable name I chose the wrong answer. Interesting to read more about while loop levels, although who would ever need/create a query with that many while loops is baffling me. 😉

An interesting question to be sure, but as a general rule, I can't stand loops. On those rare occasions when they're necessary, I'll begrudgingly use one, but I still don't like them.

I think the only thing I take away from this question is confirmation that dynamic SQL must be avoided, but if you need it you should at least name your variables with a little more care...

Just because you're right doesn't mean everybody else is wrong.

Personally I detest questions like this. This is testing our ability to be a human compiler and debug code that faced with in the real world I would toss out and rewrite. To me this does not follow the spirit of the QOTD which is to test our knowledge of various aspects of sql server. It doesn't help that the site does a rather lousy job of formatting. While I don't like the question I applaud the effort and hope to see more questions from Shiva in the future.

I got a different error than was indicated,

Msg 102, Level 15, State 1, Line 1289

Incorrect syntax near 'END'.

But when I reduced @intMaxLoop from 162 to 161, it worked. So I chose that option, which was wrong. Humph.
