[hibernate-issues] [Hibernate-JIRA] Created: (HHH-3095) Invalid queries when using subclasses and one-to-many associations

Invalid queries when using subclasses and one-to-many associations ------------------------------------------------------------------ Key: HHH-3095 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3095 Project: Hibernate3 Issue Type: Bug Components: query-sql Affects Versions: 3.2.5 Environment: Hibernate 3.2.5, bug identified on sybase Reporter: Sebastien Blind Priority: Blocker Attachments: src-cat.zip This bug report builds on top of the topic found in the forum at http://forum.hibernate.org/viewtopic.php?t=977453 Basically, there seems to be an issue in the way hibernate treats a collections of objects that extend a base class. The attached example has: a Cat class a DomesticCat class (extends Cat) a Cage class (can contain multiple DomesticCat) The generated SQL is below - the filter cats0_.CAGE_ID=? should really be cats0_1_.CAGE_ID=? select cats0_.CAGE_ID as CAGE3_1_, cats0_.CAT_ID as CAT1_1_, cats0_.CAT_ID as CAT1_0_0_, cats0_1_.CAGE_ID as CAGE2_2_0_ from CAT cats0_ inner join DCAT cats0_1_ on cats0_.CAT_ID=cats0_1_.CAT_ID where cats0_.CAGE_ID=? As of now, I am not aware of any configuration that would work around this problem. Please let me know if you know otherwise.
