Heath Thomann updated OPENJPA-2475:
-----------------------------------
Attachment: OPENJPA-2475-2.1.x.test
> A query with LEFT FETCH JOIN returns incorrect results.
> -------------------------------------------------------
>
> Key: OPENJPA-2475
> URL: https://issues.apache.org/jira/browse/OPENJPA-2475
> Project: OpenJPA
> Issue Type: Bug
> Components: query
> Affects Versions: 2.1.1, 2.2.2, 2.2.1.1, 2.3.0, 2.4.0
> Reporter: Heath Thomann
> Assignee: Heath Thomann
> Priority: Minor
> Attachments: OPENJPA-2475-2.1.x.test
>
>
> Take the following two entities:
> @Entity
> public class DepartmentTest{
> @Id
> private String primaryKey;
> @OrderBy("name")
> @OneToMany(mappedBy = "departmentTest")
> private Set<PersonTest> persons = new HashSet<PersonTest>();
> ...........
> @Entity
> public class PersonTest {
> @Id
> private String primaryKey;
> @ManyToOne
> @ForeignKey
> private DepartmentTest departmentTest;
> private String name;
> .....
> With these entities, take this JPQL:
> "SELECT DISTINCT dept FROM DepartmentTest dept LEFT JOIN FETCH dept.persons";
> Depending on the data in the database (the order is important, see the
> provided test), this query can return a results set where some of the
> 'persons' are missing.
> Thanks,
> Heath Thomann
