I'm hoping by this afternoon I will have read the explanation enough times to understand it, because I sure as heck don't at this hour of the morning! ;-)

Thanks for an interesting question. I got the right answer but not by thinking it all the way through so I learned something new - always a good way to start the morning!

I think I may need eye glasses, I really had to look hard at the commas to differentiate them from periods... I almost chose the Incorrect Syntax error.

My first opinion was: very exotic question far away from practical usage.
But later I changed my minds. Never thought about arithmetical operations in T-SQl work in such way. Thanks a lot.

Ah yes, my "favorite" bit of SQL syntax

select 0 [A]



A fun bug to find when I accidentally delete a comma and then try to figure out what's wrong with the output of

select col1
col2,
col1003
from sometable



What? I can't be the only one!Ermm

Thanks for the question!
