[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3684?page=c... ] Gail Badner updated HHH-3684: ----------------------------- Description: Two unit tests fail: UnionSubclassTest.testUnionSubclassFetchMode().. UnionSubclassPropertyRefTest.testOneToOnePropertyRef() This may be due to a bug in Sybase. A similar problem is discussed here: http://www.forumtopics.com/busobj/viewtopic.php?p=442226&sid=40bd9624... For UnionSubclassTest.testUnionSubclassFetchMode(), changing: select ... from ( select ... from humans union select ... from employees ) this_ inner join locations location2_ on this_.location=location2_.id left outer join ( select ... from employees union select ... from humans union select ... from aliens ) beings3_ on location2_.id=beings3_.location : to: select ... from ( select ... from humans union select ... from employees ) this_ inner join (locations location2_ left outer join ( select ... from employees union select ... from humans union select ... from aliens ) beings3_ on location2_.id=beings3_.location) : on this_.location=location2_.id fixes the problem. This change is similar to what is documented for a "right-nested outer join" at http://infocenter.sybase.com/help/topic/com.sybase.infocenter.dc32300.150.... was: This is reproduced by UnionSubclassTest.testUnionSubclassFetchMode()..

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3684?page=c... ] Gail Badner commented on HHH-3684: ---------------------------------- It looks like the tests may be failing for different reasons. UnionSubclassPropertyRefTest.testOneToOnePropertyRef() is failing on a query like: select ... from U_SBCLS_PROPREF_ACCT account0_ inner join U_SBCLS_PROPREF_CUST customer1_ on account0_.customerPersonId=customer1_.personId inner join ( select ... from U_SBCLS_PROPREF_PERS union select ... from U_SBCLS_PROPREF_CUST ) person2_ on account0_.personId=person2_.personId but succeeds in the following when the order of inner joins is changed: select ... from U_SBCLS_PROPREF_ACCT account0_ inner join ( select ... from U_SBCLS_PROPREF_PERS union select ... from U_SBCLS_PROPREF_CUST ) person2_ on account0_.personId=person2_.personId inner join U_SBCLS_PROPREF_CUST customer1_ on account0_.customerPersonId=customer1_.personId Is this a bug in Sybase? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira

[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3684?page=c... ] Gail Badner commented on HHH-3684: ---------------------------------- A difference between the two failures is that the query for UnionSubclassTest.testUnionSubclassFetchMode() has a "right-nested outer join"; UnionSubclassPropertyRefTest.testOneToOnePropertyRef() only involves inner joins. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
