String hql
=
"
select u.name,u.password from User u
"
;
Query query
=
session.createQuery(hql);
Iterator iter
=
query.iterator();
while
(iter.next())
{
Object obj[]
=
(Object[]iter.next());
System.out.println(obj[
0
]
+
obj[
1
]);
}
以上代码需要逐一去访问结果集，非常不方便
Hibernate的HQL语言提供了 动态构造实例对象的方法
String hql
=
"
select new User(u.name,u.password) from User u
"
;
Query query
=
session.createQuery(hql);
Iterator iter
=
query.iterator();
while
(iter.next())...
{
User u
=
(User)it.next();
System.out.println(u.getName()
+
u.getPassword());
}
特别需要注意的是，对应实体对象中使用指定属性值的构造函数一定要存在
