Java 将select中带有subselect的SQL转换为HQL

我有以下SQL，我在转换为HQL时遇到问题。一个NPE被抛出——我认为这与求和函数有关。另外，我想在subselect别名上排序——这可能吗

SQL（子选择）：

HQL（不工作）

如果有人感兴趣，以下是工作HQL：

SELECT q, 
(SELECT COALESCE(SUM(CASE v.voteUp WHEN true THEN 1 ELSE -1 END), 0) 
FROM Vote v WHERE v.question = q) AS votecount
FROM Question AS q
LEFT JOIN q.author u
LEFT JOIN u.blockedUsers ub
WHERE q.dateCreated BETWEEN :week AND :now
AND u.id NOT IN (
    SELECT ub.blocked FROM UserBlock AS ub WHERE ub.blocker =:loggedInUser
)
AND (u.blockedUsers IS EMPTY OR ub.blocked !=:loggedInUser) 
ORDER BY col_1_0_ DESC

请注意col_1_0的顺序_

Hibernate存在一个公开的问题——它不能正确解析别名，并且由于别名在查询中被重命名，因此将抛出一个错误。因此，col_1_0_基本上是一种变通方法——它是Hibernate生成的名称。 见问题：

出于好奇：为什么要在如此复杂的hql查询中翻译一个简洁的sql查询？您能帮我做一下吗

SELECT q, 
    (SELECT COALESCE(SUM(IF(v.voteUp=true,1,-1)), 0) 
    FROM Vote v WHERE v.question = q) AS votecount
    FROM Question AS q
    LEFT JOIN q.author u
    LEFT JOIN u.blockedUsers ub
    WHERE q.dateCreated BETWEEN :week AND :now
    AND u.id NOT IN (
        SELECT ub.blocked FROM UserBlock AS ub WHERE ub.blocker = :loggedInUser
    )
    AND (u.blockedUsers IS EMPTY OR ub.blocked != :loggedInUser) 
    ORDER BY votecount DESC

SELECT q, 
(SELECT COALESCE(SUM(CASE v.voteUp WHEN true THEN 1 ELSE -1 END), 0) 
FROM Vote v WHERE v.question = q) AS votecount
FROM Question AS q
LEFT JOIN q.author u
LEFT JOIN u.blockedUsers ub
WHERE q.dateCreated BETWEEN :week AND :now
AND u.id NOT IN (
    SELECT ub.blocked FROM UserBlock AS ub WHERE ub.blocker =:loggedInUser
)
AND (u.blockedUsers IS EMPTY OR ub.blocked !=:loggedInUser) 
ORDER BY col_1_0_ DESC
