问题描述

如果我的查询包含一个类,比如:

  query = session.createQuery(select User from u ); 
queryResult = query.list();

然后迭代它,其中 queryResult 是一个 User 类的对象。

那么如何从包含多个类的查询中得到结果呢?例如:

 从User中选择u,g作为u,Group作为g,其中u.groupId = g.groupId和g。 groupId = 1 


解决方案
  for(Object [] result:query.list()){
User user =(User)result [0];
Group group =(Group)result [1];
}


If my query contains one class, like:

query = session.createQuery("select u from User as u");
queryResult = query.list();

then I iterate it, where queryResult is an object of User class.

So how to get result from query which contains more than one class? For example:

select u, g from User as u, Group as g where u.groupId = g.groupId and g.groupId = 1
解决方案
for (Object[] result : query.list()) {
    User user = (User) result[0];
    Group group = (Group) result[1];
}
