Make a class that implements IInterceptor

then give that class as param to the session like

SessionManager.SessionFactory.OpenSession(new newClass()));

in the class you need to give your implementation to

public NHibernate.SqlCommand.SqlString OnPrepareStatement(NHibernate.SqlCommand.SqlString sql)
{

}

each query that will run on this session will be intercept here and there you can add some sql
