> Running the following produces the error seen in Derby 10.3.X but not in
> 10.2.X nor in 10.1.X.
> Don't know if this related to DERBY-3231.
> First query is incorrectly sorted whereas the second one is okay when there
> is an index on the table.
> If the table is not indexed, the sort works correctly in DESC order.
> ------
> create table CHEESE (
> CHEESE_CODE VARCHAR(5),
> CHEESE_NAME VARCHAR(20),
> CHEESE_COST DECIMAL(7,4)
> );
> create index cheese_index on CHEESE (CHEESE_CODE DESC, CHEESE_NAME DESC,
> CHEESE_COST DESC);
