Good question but the correct answer is "0 " (with 2 trailing spaces), not "0".#

Edit: Add example:
SELECT REPLACE(ISNULL ( CONVERT (char(3),1/9),'*'),' ','<Space>') AS Ret


0<Space><Space>


That's correct. Convert to varchar to remove the trailing spaces. :-)

Really easy question, but the explanation puzzles me. As far as I can see it is no implicit conversion, just a pure integer division.


I assume it is a reference to the 1 and the 9 being interpreted as integers.

I guess I'm the only one that initially looked for '1/9' as an answer choice. Doh.

Nice question, but it's a pity that the correct answer isn't any of the options. I picked '0' as it's the least wrong, but it definitely is wrong. The correct answer is '0 ' (two trailing spaces) and '0' isn't even a possible value for a char(3) object.

Technically the answer is '0 ', but it was easy enough to deduce the answer choice that the author was looking for. If "None of the above" had been a choice then I imagine the comments on this thread would be much more "spirited". :-)

Good question overall. Thanks Eli!
