hello everybody,

we are going to map instances of an object (depends on the value of an attribute) on several tables.

Is this possible (without subclassing), or we have to extend this class in several subclasses and then map any subclass using discriminator?

Ifn the case of possiblity without extending the class, how can we do it?

We are using hibernate 3.0.5 .


Thanks in advance,
Reza

I'm not sure if it's possible but I am fascinated by why you would want to do this. Why? Why would you ever need to map a single object to multiple tables based on the value of an attribute unless the class was a good candidate for subclassing using a discriminator?

Hello Jamie,

the reason is that we have an existing database model which we must not change on one hand and we have identical functionality for each of these tables on the other hand.

Currently, the functionality is duplicated for each table. Since we currently implement the functionality on a new platform (Spring with either Hibernate or iBatis), we don't want to keep this "historic" design flaws in our new business logic and expect the persistence tier to be able to map the domain object to database tables, even if it is not trivial like in this case ;-)
