In ODB 2.2.0 we've added multi-database support which required some
changes to the traits structure. The table name is still there, but
it is now in the database-specific object_traits_impl class rather
than common object_traits (it is possible to map the same class to
different tables in different databases).

If you don't use multi-database support, then you can access the
table name like this:

odb::object_traits_impl<my_object, odb::id_common>::table_name

If you do use multi-database support, then you will need to specify
the database, for example:

odb::object_traits_impl<my_object, odb::id_sqlite>::table_name
