CompletenessTest fails when navigating a self-referencing relationship

• Key: JDO-93
• Type: Bug
• Status: Closed
• Resolution: Fixed
• Priority: Major
• Assignee: Erik Bengtson

• Fix Version/s: JDO 2 beta

Description

Running the CompletenessTest results in a JDODataStoreException with a nested exception complaining about the generated SQL:
ERROR 42X03: Column name 'APPLICATIONIDENTITY0.PERSONS.PERSONID' is in more than one table in the FROM list.

The test traverses a graph of persistent objects and calls getProtege on a FullTimeEmployee instance. This navigates the protege<->mentor relationship specified in the superclass Employee. Please note, protege<->mentor is a self referencing relationship from Employee to Employee.

The error message reads as if the generated SQL misses to specify a table alias for the table in the JOIN clause.

I use the following configuration stored in test/conf/onetest.conf:
jdo.tck.description = Completeness test with standard mapping, basic testdata with no relationships.
jdo.tck.classes = org.apache.jdo.tck.mapping.CompletenessTest
jdo.tck.testdata = org.apache.jdo.tck.pc.company.companyNoRelationships.xml
jdo.tck.standarddata =
jdo.tck.mapping = 0

This is the maven call:
maven -o -Djdo.tck.cfglist=onetest.conf -Djdo.tck.identitytypes=applicationidentity runtck.jdori

Here is the stacktrace:
test(org.apache.jdo.tck.mapping.CompletenessTest)javax.jdo.JDODataStoreException: Fetch request failed: SELECT applicationidentity0.PERSONS.PERSONID FROM applicationidentity0.PERSONS LEFT OUTER JOIN applicationidentity0.PERSONS ON applicationidentity0.PERSONS.PERSONID = applicationidentity0.PERSONS.MENTOR WHERE (applicationidentity0.PERSONS.PERSONID = ?)

I have a fix for JPOX for this, but currently SourceForge CVS is down (for up to 36 hours). I'll check it in when they allow us access ;-)

[Michael Bouschen]

The issue is fixed with the JPOX nightly build from 11-Aug-2005.

Reopened to set the Fix Version/s field to JDO 2 beta.
