syntax

Hi all, I just stumbled upon something in ORACLE SQL (not sure if it's in others), that I am curious about. I am asking here as a wiki, since it's hard to try to search symbols in google...

I just found that when checking a value against a set of values you can do

WHERE x = ANY (a, b, c)

As opposed to the usual

WHERE x IN (a, b, c)

So I'm curious, what is the reasoning for these two syntaxes? Is one standard and one some oddball Oracle syntax? Or are they both standard? And is there a preference of one over the other for performance reasons, or ?

Just curious what anyone can tell me about that '= ANY' syntax. CheerZ!
