Question

Hibernate的Dao类继承了HibernateDaoSupport类后如何在排序后得到前5条数据？给个例句(HQL).

Answer 1

String hql =new String();
hql = "select p from Problem p order by p.problem_id DESC";
Query q = (Query) session.createQuery(hql);
q.setFirstResult(from);
q.setMaxResults(pageSize);

Answer 2

setFirstResult()【设置从哪条记录开始取】和setMaxResult()【最多取多少条记录】方法。
