It's on my list, but it's low priority because most non-trivial db
schemas will contain constructs that cannot survive a round-trip
through RDBO. Column constraints or database triggers that include
arbitrary procedural code in the database, for example, cannot be
converted to the "Perl equivalent" by the auto-init system in RDBO.
These things would therefore be lost in a round-trip.
That said, for simple schemas, creating SQL from an RDBO class should
definitely be possible. When I do it, I plan to leverage
SQL::Translator, if possible.
If anyone else wants to work on this bit, I think it mostly involves
writing code for the SQL::Translator module, with only trivial hooks
in RDBO. The usage would look like this:
print Foo->meta->sql_table_definition($db);
where $db is a Rose::DB-derived object used to determine the SQL
syntax (MySQL, Pg, etc.)
