Knut Anders Hatlen updated DERBY-4001:
--------------------------------------
Attachment: d4001-1a-test.diff
Attaching a patch - d4001-1a-test.diff - which adds a (not yet enabled) test
for this bug. I've written test cases for all the problematic cases I've found.
All the queries (except two which I included for completeness and marked with a
comment) fail without the fixes suggested in an earlier comment. The test
checks both that the correct rows are returned and whether or not the queries
are flattened.
Committed revision 765930.
> Sequence comparison with "ALL" does not yield correct results

> A query involving "< ALL" does not yield the right results for decimal
> datatype. "< ANY" works, though.
> To reproduce the issue:
> % create table t1(col1 decimal(10,5));
> % insert into t1 values (-21483.64800);
> % insert into t1 values (74837.00000);
> % select col1 from t1 where col1 < ALL (select 0.0 from t1);
> The above yields no results whereas it should return the first row.
