In ORM you have 3 strategies -TablePerClass -TablePerClassHierarchy -TablePerConcreteClass
with NH you have 4 -TablePerClass -TablePerClassHierarchy -TablePerConcreteClass -TablePerClassHierarchy where some class can be split in another table (mix TablePerClassHierarchy with TablePerClass starting from TablePerClassHierarchy) What you want is start from TablePerClass and end in TablePerClassHierarchy. Probably if you can send us your classes and a little explication we may help you to choose the right strategy. btw you should ask yourself why you need to split part of the graph from B on. 2010/2/23 Dzyann <[email protected]> > Hi, > > I have been reading the documentation of NHibernate and I think that I > am trying to accomplish is not possible, but i wanted to make sure > here. > > Basically what i want is having: > -Class A > -Class B -> inherits A > -Class B1 -> inherits B > -Class B2 -> inherits B > -Class B3 -> inherits B > > Map A in a Table, B in another Table, but B1, B2 and B3 in the same > table than B. > > Reading in the documentation i found: > "It is possible to use different mapping strategies for different > branches of the same inheritance hierarchy, and then make use of > implicit polymorphism to achieve polymorphism across the whole > hierarchy.
