situation: - user entities in db (properties id, name, sex, age) - you want to get the oldest of them with min. age 10
createQuery(select u from User u where u.age>=10 order by age desc) query.setMaxResults(1) !!! query.getResultList(); how GAE handles this situation? 1. search in index table where age>=10 and only the oldest 2. found 1 entity key 3. read entity 4. return entity OR 1. find all of them in index table where age>=10 2. found X entity keys 3. read all entities 4. return only the oldest of them (because JPA maxResults=1) Thanks -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.
