[antlr-interest] MySQL grammar -- can I submit?

[Maciej Gawinecki]

Dear all,

I've started to work on MySQL dialect of SQL grammar as I haven't found 
anything like this on the net. Unfortunately, the grammer is currently 
incomplete as I don't have time to continue the project due some 
deadlines and other projects.

I'm not sure about the quality of my solution, as I'm a newbie to ANTLR 
and this was my first project on grammars for this framework. I've 
studied context-based and context-less grammars and I've used yacc but 
it was so many years ago... Nevertheless I still would like to share 
with my partial results, to make it maybe starting point for other people.

DOES IT SOUND REASONABLE? DOES IT MAKE ANY SENSE FOR YOU, AS A COMMUNITY?

Regards,
Maciej

Technical details:
* The grammar was created on the base of yacc grammar provided in MySQL
   5.1 source distribution (particularly 'sql_yacc.yy' file). Parts of
   lexer for type casting (recognizing different integer types) I've
   adopted into Java acion also from MySQL source distribution.

* The grammar is for ANLTR v3 and contains some minor Java actions for
   collecting information about: comments (first parser pass on
   COMMENTS_CHANNEL) and identifiers of tables/columns (second pass on
   DEFAULT_CHANNEL). They can be easiliy removed.

* More complete are parts relating to CREATE TABLE section, as it was of
   my main interest.
