If you are generating query support (--generate-query/-q), then
the table name (as const char* string) can be obtained like this:

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

Where T is the object type.

There is no way to get the name of the column corresponding to
the object id. So I suggest that you either use the same data
member name for all your object ids (e.g., id_) and then use
the column name that ODB derives. Or you can assign the column
name explicitly with the 'column' pragma.
