Hibernate HQL语句

查询

String hql=”from User user ”;List list=session.CreateQuery(hql).list();

更新

Transaction trans=session.beginTransaction();String hql=”update User user set user.age=20 where user.age=18”;Query queryupdate=session.createQuery(hql);int ret=queryupdate.executeUpdate();trans.commit();

删除

Transaction trans=session.beginTransaction();String hql=”delete from User user where user.age=18”;Query queryupdate=session.createQuery(hql);int ret=queryupdate.executeUpdate();trans.commit();

HQL语句不能用于插入数据！
