> Key: OPENJPA-2179
> URL: https://issues.apache.org/jira/browse/OPENJPA-2179
> Project: OpenJPA
> Issue Type: Bug
> Components: kernel
> Affects Versions: 2.2.0
> Reporter: Mark Struberg
> Assignee: Mark Struberg
> Fix For: 2.3.0
>
> Attachments: OPENJPA-2179-test-1.patch
>
>
> I have an Entity (Course) with a simple @Embedded field and a @Lob. I do not
> use any LAZY attribution on them!
> If I do a normal em.find, the entity will be loaded as a whole (all the
> fields, including the embedded and the lob will be fetched immediately).
> Sidenote: the Lecturer referred in the select is defined as
> @OneToMany(mappedBy = "course",
> cascade = {CascadeType.PERSIST, CascadeType.REMOVE,
> CascadeType.MERGE},
> orphanRemoval = true, fetch = FetchType.EAGER)
> @OrderColumn(name = "POSITION")
> private List<Lecturer> lecturers;
> The following selects DO work
> * "select c from Course c join c.lecturers l "
> * "select distinct c from Course c"
> The following selects create tons of subqueries! 1 separate sub-query for
> each @Embedded field, and also for each @Lob
> * "select distinct c from Course c join c.lecturers l "
> * "select distinct c from Lecturer l join l.course c"
> * "select c from Lecturer l join l.course c"
> This happens ONLY if I run this stuff against Oracle. In MySQL it seems to
> work properly.
> I'll try to create a unit test for it.
