Dag H. Wanvik commented on DERBY-5933:
--------------------------------------
I checked the resulting tree after the preprocess phase of optimization, and
the column reference to A1 is indeed already labeled (4,1). The enclosed log
file shows this to be the case after end of the optimization phase. The
problematic labelling happens during preprocess time, at which time the
flattening occurs.

> Hello
> I have a simple database with 100 records.

> This query was generated by Hibernate ORM.
> In certain circumstances the result rowset is not sorting.
> When I use condition morefld2_.mf_id in (5) the result is unsortable.
> When I use condition morefld2_.mf_id in (5,0) the result is sorting properly.
