I need to remove that from the documentation, it's no longer true. As you saw, DBD::AnyData does handle multiple tables in a single SQL statement now. Just an oversight in not updating the documentation.
The latest SQL syntax for DBD::AnyData will always be found in the SQL::Parser documentation that is part of the SQL::Statement distribution. AnyData gets all of its SQL abilities from SQL::Statement and SQL::Parser so keeping them up to date is important.
I'd prefer that most reports go to the dbi-users@perl.org mailing list, or directly to me, or as a bug report on rt.cpan.org. I can also often be found on PerlMonks as jZed. CPAN-forum is a great tool but as an author I already have all those other places I need to keep an eye on and I'd prefer not to have another.
Thanks again for writing,
