hql中new对象查询特点
在Hibernate的hql语句中可以用例如select new com.domain.User(name,passwd) from Users形式

    String hql = " select new com.domain.User(name,passwd) from Users";           Query query = session.createQuery(hql);    //默认查询出来的list里存放的是一个Object数组，但是在这里list里存放的不再是默认的Object数组了，而是User对象了               List<User> users = query.list();                  for(User user : User){                          String name = user.getUsername();               String passwd = user.getPassword();                System.out.println(name + " : " + passwd);              } 

代码引用的是网游的代码，在开发一般查询这种方式用的不多，在多表查询时用处会挺大，做个备忘吧 呵呵 SELECT new com.domain.User (TRIM(class.id), TRIM(school.id) ) FROM Class class, School school WHERE (1 = 1) AND (class.id = school.classid) ORDER BY class.id 2 楼 刘浩4611 2011-08-05 SELECT new com.domain.User
(
TRIM(class.id),

TRIM(school.id)
)
FROM Class class, School school
WHERE (1 = 1)
AND (class.id = school.classid)
ORDER BY class.id
