inheritance - Fluent NHibernate Create entity mapping for overlapping entities -

for eg. have 2 tables in database

nonresidentstudents - columns studentid, studentname, modeoftransport

residentstudents - columns studentid, studentname, dateofjoininghostel

studentid , studentname common columns , last column uncommon between two

for reason, cant change these tables or define common master table , make uncommon columns in sub tables. table stucture rigid.

now when trying create entity , mapping above schema using fluent nhibernate (only) know if can define sort of common entity , common mapping common columns , create child entities inheriting common entities. in child entity , mapping class have representations uncommon columns. please share code of how it.

i did before.

common class

public class basemapping : classmap<entitybase>{      public basemapping ()     {         useunionsubclassforinheritancemapping ();         // rest of mapping attributes     } } 

for individual classes inherit base this:

public class departmentmapping : subclassmap<department> {     public departmentmapping ()     {         abstract ();         // map unique attributes     } } 

the code above create 1 class based on department , entitybase. not create table called entitybase.
