[antlr-interest] ISO SQL 2003 Grammar

[Ivan Bludov]

By the way there are generated java parser and lexer included in the
corresponded SQL archive
(http://www.antlr.org/grammar/1304304798093/SQL2003_Grammar.zip). So
lexer is built with antlr 3.4 and the parser with antlr-3.3. As I
wrote I didn't meet any problems for building with antlr-3.3 on my
laptop with 4G RAM. But your attached java files couldn't be compiled
because they include errors previously described:

So some of these errors could be fixed manually. But the error about
duplicated case - I think - references to the some incorrect behaviour
of antlr.
