APAR Error Description / Circumvention

-----------------------------------------------
Queries which select and order on DECFLOAT columns may produce
an incorrect number of results and/or incorrect values. This can
occur when the optimizer chooses an Index Merge access plan to
implement the query. Visual Explain can be used to verify the
access plan used for a query.

CORRECTION FOR APAR MA46736 :
-----------------------------
When building a temporary indexed list to implement the Index
Merge access plan, the optimizer may incorrectly store and
project DECFLOAT data. This fix corrects the optimizer behavior
so that the data is stored correctly in the temporary indexed
list.

CIRCUMVENTION FOR APAR MA46736 :
--------------------------------
None.
