Presumable, the EXISTS sub-query can be optimized sometimes to just stop processing the sub-query and kick things back out to the outer query.



IN has to process them all and find them all.



Don't forget the special case use as well:

IF NOT EXISTS `universe` THEN bigbang()


Ash

any chance of writing the implementation of that bigbang() function?
If nothing exists and a universe is created via a big bang... does it
make a sound? Can we realistically call it a big bang if it doesn't make
a sound? Couldn't we call it the big light show? But then again... if
nothing exists and a universe is created via a big light show... does it
matter? Can it be perceived? Is this just a proverbial pandrödinger's
box? You can't implement the bigbang() function if you don't exist.

The function doesn't say who's doing the creating, it just checks for
the existence of the universe.
How do you know? Are you... God?

;)

Rob.

Sorry, term foul-up.  I meant the statement doesn't say who's doing the
creating, it just checks for existence of the universe.

Thank you,
