Here is a more detailed answer. A case when a criteria for a
subclass / superclass is based on a presence of a given relationship
is better addressed with vertical inheritance - something we'll be
adding in 3.0. Single table inheritance mapping requires a criteria
based on one or more columns of the root table.

Do I have to add another column just to hold the type like the

I guess it can be done if need be.
That would certainly work.
