Hi folks,

I am using libgda to parse all queries on my app, however I saw that
sub-queries that had an alias were not working, for instance:

  SELECT foo.abc FROM (select abc from bar) foo;

See this is valid on sqlite3:

sqlite> create table bar(abc varchar(10));
sqlite> insert into bar values('hi');
sqlite> SELECT foo.abc FROM (select abc from bar) foo;
hi

Seems like that syntax was not handled by the parser.y lemon file. So I
have a patch for it:
https://github.com/arthurnn/libgda/commit/0ba0e8f49f90304256e4fca637928d8cad55a1e0

Let me know what is the proper way to contribute to this library, if
sending a Pull Request on GitHub, or sending a .patch file on the mailing
list.

Let me know if this makes sense

Thanks a lot
