Question

SELECT id, comment, team_name 
    from XYZ
    INNER JOIN (
    SELECT id 
    from ABC 
    where team.id= "XYZ" 
    GROUP BY id 
    ORDER BY COUNT(id) DESC
) on XYZ.id=ABC.id where XYZ.id="ABC"

该问题的解决方案是什么，因为我无法对HQL中的子查询进行内部联接。

Answer 1

解决方案是仅对所有列使用GROUP BY

SELECT s.assignedTo.id, s.assignedBy.id, s.comment, s.assignedTo.team.team_name, COUNT(s.assignedTo.id) 
FROM Star s 
WHERE s.assignedTo.team.team_id=:teamName  
GROUP BY s.assignedTo.id,s.assignedBy.id, s.comment,s.assignedTo.team.team_name
ORDER BY s.assignedTo.id;

HQL中的子查询的内部联接
