I have an SP that returns 4 columns of a table. I have a corresponding class with 4 properties.. and a mappping file with 4 properties. Everything is just fine so far.

I have another SP that returns 2 columns from same table. I want to make use of same class and mapping file. But it throws an exception here because Nhibernate expects 4 paramerts but SP returns only 2.

How can i tell Nhibernate to ignore mapping for other 2 columns which SP is not returning? Please advise. Any help would be highly appreciated. Thanks in advance.
