Many-to-one issue

I am a newbie at NHibernate. I have a problem with "many-to-one" relations.
I have a class Node:

Code:

public class Node
{
  public int Id;
  public string Name;
  public Node Parent;
}

When I get a "Node", Parent field isn't fetched(Parent is null). In real, I don't need all Parent properties, only the "Id", and I don't want to access the table again.
So is it possible to get only the foriegn column without accessing the whole class?
Thanks for your help.

You have two possibilities:

1) Just map the id instead of the object
2) Use lazy loading. Hibernate will create an proxy object and handle lazy loading of the object for you. And you can access the Id getter of the object without hibernate initializing the full object (meaning no call to the db). Check the documentation for more information
