A caveat: typically, a descriptive grammar needs to be tweaked (often
a lot) to be useful as an input to parser generators, though, due to
grammar class restrictions. JavaCC is of type LL(k),
cf. http://en.wikipedia.org/wiki/Category:Parsing_algorithms
How far the ISO SQL grammar is from being LL(k) "out of the box", I
don't know.
