Subject [jira] Commented: (JDO-246) JPOX eliminates duplicates in the query result although DISTINCT is not specified.
Date Tue, 31 Jan 2006 21:28:34 GMT
    [ http://issues.apache.org/jira/browse/JDO-246?page=comments#action_12364722 ] 

Craig Russell commented on JDO-246:
-----------------------------------

It might be easier to think about this if we add another projection to the SELECT:

SELECT employee.id, employee.manager.lastname FROM org.apache.jdo.tck.pc.company.Department
WHERE employees.contains(employee) VARIABLES Employee employee

Here, the results should be:

{1, "emp2Last"}
{2, null}
{3, "emp2Last"}
{4, "emp2Last"}
{5, "emp2Last"}

Simply removing employee.id should not change the number of rows of the result. It should
only change the number of columns returned by the query.
