List of Supertype and @OrderBy [message #388438] Thu, 28 May 2009 11:16 Go to next message

Hi,

I am still working with Toplink Essentials but I think this is related
to EclipseLink.

I have a List<Einwirkung> where "Einwirkung" is an abstract Supertype.
"Einwirkung" holds a field "int sortIndex" which stores the runtime
order of the List elements.

To ensure the prior element order, I annotaded the List<Einwirkung> with
@OrderBy("sortIndex ASC")

When TopLink loads this list, it splits the SQL-statements according to
the concrete "Einwirkung"-Types and then aggregates the results in the
List. Please see the Logging below.
Each partial result is ordered by the SORT_INDEX field correctly but
because of the aggregation the final List is ordered first by Concrete
Type and second by SORT_INDEX.

How can I achieve that the List is orderd by the sortIndex field as
described in my annotation ?
Is this an issue and - if so - is it already fixed in EclipseLink ?

Thanks
Sebastian

Yes, we have addressed this in EclipseLink. There is a setting on the
underlying native query to use an outer join. This enables a single SQL
call where the ordering can be maintained.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=270147

I do not believe this functionality is available in TopLink Essentials.
