/*
Oracle PL/SQL grammar built with ANTLR v3.2 and v3.1.3. I only vouch that it works for v3.2, though.
Author: Patrick Higgins
License: GNU Lesser General Public License, version 2.1 or (at your option) any later version.
I have used a swallow_to_semi trick to avoid parsing SQL statements and other statements that were not of value to me.
The idea was that a separate parser for SQL would be created (I believe this is what Oracle itself does).
Nearly all of the PL/SQL language from 11g is in this grammar, though. It works on all files in a fairly large code
base.
This has some limited support for parsing SQL*Plus files, which turns out to be pretty hard to work into ANTLR.
It works for my usage, but I think doing it properly would mean writing a Java class to parse the SQL*Plus language
(which is pretty simple and shouldn't need ANTLR) and another adapter for ANTLR which enables tracking back to the
original source line numbers. This PL/SQL parser might be invoked many times for each SQL*Plus file.
