Jan Schatteman ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiMTI5M2EzN2I0... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16494?atlOrigin=eyJpIjoiMTI5M2... ) HHH-16494 ( https://hibernate.atlassian.net/browse/HHH-16494?atlOrigin=eyJpIjoiMTI5M2... ) Right or full joining on single tablepolymorphic entities gives incorrect results ( https://hibernate.atlassian.net/browse/HHH-16494?atlOrigin=eyJpIjoiMTI5M2... ) Change By: Jan Schatteman ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) See {{JoinWithSingleTableInheritanceTest}}.{{testRightJoinOnSingleTableInheritance}}`and {{JoinWithSingleTableInheritanceTest.testFullJoinOnSingleTableInheritance}} for examples of this. The problem is that the {{<tablealias>.dtype=xxx}}part gets added to the on clause, and this leads to incorrect results. [~accountid:557058:0222998d-a0c8-4789-91ec-6a92d10dfb9a] stated that that condition should be pushed down into the tablereference, e.g `ight join (select * from child_tbl where disc = 'child_a') c on ...` The aforementioned tests have been disabled for now, but should be reenabled when this is fixed.
