Hibernate Native SQL Query retrieving entities and collections

Question

This is my situation, I have two basic POJO\'s which I\'ve given a simple hibernate mapping :

Person
  - PersonId
  - Name
  - Books

Book
  - Code
  - Descr         


        

Answer 1

Expanding on Mathews answer. To force hibernate to only return a list of persons do:

List peopleWithBooks = session.createSQLQuery(
   "select {p.*}, {b.*} from person p, book b where ").
     .addEntity("p", Person.class)
     .addJoin("b", "p.books")
     .addEntity("p", Person.class)
     .setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY)
     .list();

Associated Book entities will be fetched and initialized without a additional call to the db.

The duplicate

 .addEntity("p", Person.class)

is necessary because

 .setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY)

operates on the last entity added.
