Yep, it only does an RTRIM, not an LTRIM.
This variation to the question may have been a better teaser :-)


Good point. In a month or so, this RTRIM/LTRIM variation would be a good question, after everyone has forgotten this question, and its discussion.

Aargh!! Again my initial reaction was "that's easy it's 5,2,2 as LEN ignores spaces"... and then "hmmm, but that's too easy, there must be a trick in there"... and after a bit of reading went against my initial conclusion...

Doh!! Sad

Good lesson though... trust yourself!


Yes, the same thing happened to me.

...I probably would have had the second option be 5, 2, 3...

Agreed. I think 5,2,5 makes no sense and should influence a decision in favor of 5,2,2.

As usual, I learn more from the discussion than the original question.

If this had been the question:

SET @aa = 'abcde';SET @bb = ' ab';SET @cc = 'ab '

I would have gotten it wrong.




(I meant no disrespect to the author of the question. My point was that a thread of "what if this" and "what if that" is always educational.)

I was a bit nervous before I answered the question that there was more to the question like what your example was.

Made me question the way char's are handled in len() as we always use varchar, so thanks!

i thought ans would be 5 2 3 but as it wasn't present i have to search and found that space is ignored
would have been better if we have option of 5 2 3. many of us would have got that wrong
