> Key: DERBY-6577
> URL: https://issues.apache.org/jira/browse/DERBY-6577
> Project: Derby
> Issue Type: Bug
> Components: SQL
> Affects Versions: 10.11.0.0, 10.10.2.0
> Reporter: Knut Anders Hatlen

> I'm seeing this on head of trunk:
> {noformat}
> ij> select c, c = all (values 'Y'), case when c = all (values 'Y') then true else false end from (values 'Y', 'N') v(c);
> C|2 |3
> -------------
> Y|true |false
> N|false|true
> 2 rows selected
> {noformat}
> Column 2 and column 3 should have the same value, but something seems to go wrong when the quantified comparison is used in a CASE expression.
> I'm seeing the expected result on 10.10.2.0, though:
> {noformat}
> ij> select c, c = all (values 'Y'), case when c = all (values 'Y') then true else false end from (values 'Y', 'N') v(c);
> C|2 |3
> -------------
> Y|true |true
> N|false|false
> 2 rows selected
> {noformat}
