[hibernate-issues] [Hibernate-JIRA] Updated: (HHH-4701) ORA-00920: invalid relational operator using subquery

ORA-00920: invalid relational operator using subquery ----------------------------------------------------- Key: HHH-4701 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4701 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.0-Beta-2 Environment: Oracle 9i Reporter: Julien HENRY Attachments: HHH-4701.patch I have the following relations: A*---B*---C All my tables are using composite keys. I want to delete all A in relation to a specific C entity. My query is: delete from A a where a in (select a1 from A a1 left join a1.b b left join b.c c where c.compositeId=:cId) The resulting Oracle query is something like: delete from A where (A_1, A_2) in (select (A_1, A_2) from A a1, B b1, C c1 where [...]) which produce the following error: ORA-00920: invalid relational operator I tried to fix the SQL query by removing parenthesis: delete from A where (A_1, A_2) in (select A_1, A_2 from A a1, B b1, C c1 where [...]) which now give the following error: ORA-00918: column ambiguously defined And finally I arrived to a correct quesry by adding table prefix: delete from A where (A_1, A_2) in (select a1.A_1, a1.A_2 from A a1, B b1, C c1 where [...]) I will try to create a test case. Is there any documentation on how to provide test case? Regards
