Vlad Mihalcea ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiNzlmNDllMDRj... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15731?atlOrigin=eyJpIjoiNzlmND... ) HHH-15731 ( https://hibernate.atlassian.net/browse/HHH-15731?atlOrigin=eyJpIjoiNzlmND... ) Multi-level Derived Tables fail with Unsupported path source: org.hibernate.query.derived.AnonymousTupleSqmPathSource ( https://hibernate.atlassian.net/browse/HHH-15731?atlOrigin=eyJpIjoiNzlmND... ) Issue Type: Bug Affects Versions: 6.1.5 Assignee: Unassigned Components: hibernate-core Created: 17/Nov/2022 01:25 AM Priority: Major Reporter: Vlad Mihalcea ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) The following derived table works fine: List<Tuple> tuples = session.createQuery(""" SELECT post_id AS post_id, post_title AS post_title, comment_id AS comment_id, comment_review AS comment_review, DENSE_RANK() OVER (ORDER BY p_pc.comment_count DESC) AS ranking FROM ( SELECT p.id AS post_id, p.title AS post_title, http://pc.id AS comment_id, pc.review AS comment_review, COUNT(p.id) OVER(PARTITION BY p.id) AS comment_count FROM PostComment pc JOIN pc.post p WHERE p.title LIKE :title ) p_pc ORDER BY post_id, comment_id """, Tuple.class) .setParameter("title", "SQL%") .getResultList(); But the following one fails: tuples = session.createQuery(""" SELECT post_id AS pid, post_title AS pt, comment_id AS cid, comment_review AS cr FROM ( SELECT post_id AS post_id, post_title AS post_title, comment_id AS comment_id, comment_review AS comment_review, DENSE_RANK() OVER (ORDER BY p_pc.comment_count DESC) AS ranking FROM ( SELECT p.id AS post_id, p.title AS post_title, pc.id AS comment_id, pc.review AS comment_review, COUNT(p.id) OVER(PARTITION BY p.id) AS comment_count FROM PostComment pc JOIN pc.post p WHERE p.title LIKE :title ) p_pc ) p_pc_r WHERE ranking <= :ranking ORDER BY post_id, comment_id """, Tuple.class) .setParameter("title", "SQL%") .setParameter("ranking", 2) .getResultList();
