Mapping: Default value

Kernel Panic · **Joined:** Wed Sep 06, 2006 8:33 am **Posts:** 19

I can map two class in a same table?

The class:

ClassA
ID
Property1

ClassB
ID
Property1

The table:
TBL
ID
ClassName
Property1

I create 2 mapping files, to ClassA and ClassB. But, the table have "ClassName" i can specify the ClassName in the mapping file to default value?

Sorry, my english is poor.

If I followed you correctly, you want to map one table in more than one objects ? Isn't it ?

If so, yes. It's possible.

If you want that one line of one would create objects of one class A or class B, then it is also possible. I guess it would be to do some kind of inheritance ? Maybe you could give a bit more realistic example so as to help us to help you :-).

Yes, you need to use subclass tag with discriminator values. You need to make your Class A and B derive from the same base class.
