My cracked crystal ball is obscuring my view but it seems you do
which will return you a date for the number of days since 1 Jan 1900
i.e. the same as
select dateadd(dd,042007,'1 Jan 1900')
An easier way to count to three? Hmmm....there's a challenge.
Seriously, I check parenthesis like this:
Start at the left with the number zero and move towards the right. Add one to your mental counter for each left parenthesis and subtract one for each right parentheses. (Notice, left-hand ones are spelled with an "is", and right-hand ones are spelled with an "es" (to tell them apart))). When you get to the end of the line, you should be back to zero.
Also, avoid using (unnecessary) parenthesis. They do not (always) make the context clearer.
If it's not practically useful, then it's practically useless.
