Venkateswaran Iyer commented on DERBY-4001:
-------------------------------------------
I forgot to add that the column has to be declared with a "NOT NULL"
constraint. Attached the output from ij.

> Key: DERBY-4001
> URL: https://issues.apache.org/jira/browse/DERBY-4001
> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.3.2.1
> Environment: Windows
> Reporter: Venkateswaran Iyer
> Priority: Minor
> Fix For: 10.4.2.0
>
>
> 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.
