我在HQL中重写了我的JDBC查询。
对于每项工作，我都有工作流程，每个工作流程都有一些任务。 任务可以是＆＃39; 0＆＃39;，＆＃39; 1＆＃39;，＆＃39; 2＆＃39;和＆＃39; 3＆＃39;并有一个BOOL专栏＆＃39;已完成＆＃39;。每个工作流程至少有一个类型的任务。我只需要获取那些工作，其工作流程只有类型为＆＃39; 0＆＃39;正在完成。
这是我的JDBC查询：
"SELECT j.*
FROM job j
INNER JOIN workflow w
ON j.id = w.job_id
INNER JOIN task t
ON t.workflow_id = w.id
WHERE j.company_id = ?
GROUP BY j.id
HAVING SUM(t.completed = TRUE AND t.type != 0) = 0"
这是我的HQL查询：
"SELECT j
FROM Job j
JOIN c.workflow w
JOIN task t
WHERE j.company_id = :companyId
GROUP BY j.id
HAVING SUM(t.completed = TRUE AND t.type != 0) = 0"
但是，运行此HQL查询会让我“期待CLOSE，找到＆＃39; =＆＃39;＆＃34; SUM子句的异常。
答案 0 :(得分：0)
"SELECT DISTINCT j
FROM Job j, Workflow w, Task t
WHERE w.job.id = j.id AND
t.workflow.id = w.id AND
j.company.id = ? AND
(SELECT COUNT(*)
FROM Task t
WHERE t.workflow.id = w.id AND
t.completed = TRUE AND
t.type != 0) = 0"
