Is it possible to configure the following inheritance mapping for a table per subclass mapping with a discriminator value:
if discriminator=="Class1" instantiate Class1
if discriminator=="Class2" instantiate Class2
in all other cases instantiate Class3 (meaning that the discriminator column can contain any value except "Class1" or "Class2").

Best regards,
Andreas

Yeah, you could use a discriminator formula for the hierarchy. Something like:

Code:

case
  when discriminator='Class1' then 'Class1'
  when discriminator='Class2' then 'Class2'
  else 'Class3'
end
