Referencing with this answer to this correlated thread, the trick posted by ehrhardt works fine.
But, what I have to do if I have to join with multiple entities? for example:
List<Person> peopleWithBooks = session.createSQLQuery(
"select {p.*}, {b.*}, {m.*} from person p, book b, magazine m where <complicated join>")
.addEntity("p", Person.class)
.addJoin("b", "p.books")
.addJoin("m", "p.magazines")
.addEntity("p", Person.class)
.setResultTransformer(Criteria.DISTINCT_ROOT_ENTITY)
.list();
Hibernate aggregates right the first join, but not the second (magazine entities are not grouped).
There are any tricks or there is a limit to join with only one correlated entity? And if I have to join with entities that have sub entities? (my goal is to retrieve all selected data with only one custom query)
