   skill.TEACH_EXP,tt.CLASS_DUR,tt.COURSE_DUR,tt.DATE_TIME from COURSE course 
   inner join SKILLSET skill on
   skill.course_id=course.s_id 
   inner join USER user on 
   user.s_id=skill.user_id 
   inner join TIMETABLE tt on
   tt.course_id=course.s_id
   where course.name IN ('course') 
   ORDER BY course.name LIMIT 10;

Answer 1

尝试如下所示。. . . .

SELECT t1.col1, t2.col2, t3.col3 
FROM Table1 t1 JOIN t1.someGroupMemebers t2 
JOIN t2.someUser t3 WHERE t3.username = 'blah blah'

Answer 2

将 JPA 用于 Hibernate 非常容易，例如：

    entityManager.createQuery("select cd from CourseDetailsVO cd join cd.course.keywords k where k.keyword in (:courseName) and cd.startDate between (:sDate) and (:eDate)", CourseDetailsVO.class);
setParameter("courseName", searchVO.getName())..
...

EntityManager 将进行处理..
