Subject [jira] Created: (OPENJPA-1365) DISTINCT keyword has no effect with JOIN FETCH queries
Date Thu, 29 Oct 2009 19:23:59 GMT
DISTINCT keyword has no effect with JOIN FETCH queries
------------------------------------------------------

                 Key: OPENJPA-1365
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1365
             Project: OpenJPA
          Issue Type: Bug
          Components: jpa, query
    Affects Versions: 1.0.4, 1.2.2, 1.3.0, 2.0.0-M4
            Reporter: Michael Dick
            Assignee: Michael Dick


This issue occurs if the proposed fix for OPENJPA-894 is in place. Without that fix there
results of a JOIN FETCH are always distinct when obtained from the database or non-distinct
when returned from the persistence context's L1 cache. 

I started a discussion on this topic on the dev mailing list. The entire thread can be seen
on Nabble here : http://n2.nabble.com/How-should-we-handle-the-JPQL-DISTINCT-keyword-td3908400.html#a3908400
