Hey guys,

is it possible with nhibernate (latest stable version) to map one domain class to multiple tables?

So if i have a class

classA
{
int identID;
string someProp;
string prop1;
string prop2;
string prop3;
}

I want to store this to four different tables. One would be for classA to store identID and someProp properties. The other three tables would be like this:

table1: identId, prop1; table2: identID, prop2; table3: identID, prop3;

How do you tell in the nhibernate mapping file that classA prop1, 2, and 3 come from a different table?

This is rather simplified as i have more than one property to store in each table. I need to do this because I cannot modify the existing data layout. Is there a way to do such a thing with nhibernate?

Thanks!

No, you have to map it as a one-to-one with other classes.

Thanks,

yeah, that's what it looked like from the docs. Just wanted to confirm I didn't miss it somewhere.

It would be a nice feature, I have wanted to this myself. Maybe just add a "table" attribute to the component element.

Yeah, that's is what I thought too. I just assumed that component had a table attribute and then the properties grouped within that component would be loaded from the specified table.
