How save child without loading parent?

Hibernate version: 2.1.6

Mapping documents: n/a

Code between sessionFactory.openSession() and session.close(): n/a

Full stack trace of any exception that occurs: n/a

Name and version of the database you are using: Postgresql 8

The generated SQL (show_sql=true): n/a

Debug level Hibernate log excerpt: n/a

I have a case where I am returned the ID of a parent in a Many-To-One relationship and I would like to add a child to the parent without first loading the parent in order to avoid the additional database query. In jdbc this would be accomplished via setting the foriegn key in the child record to equal the parent id. How is this accomplished in hibernate?

Thanks in advance.

Code:

Parent p = new Parent();
p.setId(parentId);
child.setParent(p);
session.saveOrUpdate(child);

This requires an inverse relationship and cascade="none" set on the child to parent relationship, correct?
