Tripped myself on this one.
Thanks Tom, learned something today, so I guess that makes it worthwhile

How annoying. You made me think! Wink

I agree this was an excellent question and explanation. I do see that one minor correction could be needed to one example given, however. You say "...for example the numeric value 37.2 can be converted to an int (37)...". Did you actually mean that an INT (@i) could be converted to the higher precedence numeric type, as obviously could be the literal value 37.2? After all, the result of that coalesce is 37.2 and not 37.

Interesting question, thank you Tom.

(even kind of knowing the output for each select statement, it tempted me to challenge self and to prove it)

Thanks for the great question Tom. It really made me think; there were so many choices and it was so early in the morning. I can definitely say I'm awake now. :-D



Everything is awesome!
