QBC ?參考：(Hibernate的QBC查詢)

//is empty and is not empty @Testpublic void testQBC(){Session session = sf.getCurrentSession();session.beginTransaction();//criterion 標準/準則/規范Criteria c = session.createCriteria(Topic.class)//from Topic.add(Restrictions.gt("id", 2)) //greater than = id > 2.add(Restrictions.lt("id", 8)) //less than = id < 8.add(Restrictions.like("title", "t_")).createCriteria("category").add(Restrictions.between("id", 0, 5)) //category.id >= 0 and category.id <= 5 ;//DetachedCriteriafor(Object o : c.list()){Topic t = (Topic)o;System.out.println(t.getId() + "-" + t.getTitle() );}session.getTransaction().commit();}

QBE ? 參考：(hibernate的QBE和QBC) 和 (Hibernate 查詢方式(HQL/QBC/QBE)匯總)
