NHibernate: Map one class to two identical tables

Question

I need to map one entity to two tables (Invoice and InvoiceHistory). It\'s not up to me to merge the two database tables in one and add a status column to differentiate them.

Answer 1

Create another entity which inherits the first entity you created and does nothing else. You can then map the new entity to InvoiceHistory, while the first one is still mapped to Invoice.
