Julian Hyde commented on CALCITE-4758:
--------------------------------------
I suspect that this issue and CALCITE-4742 are the same ({{ALL}} is dual to
{{SOME}} aka {{ANY}} via [de Morgan's
laws|https://proofwiki.org/wiki/De_Morgan%27s_Laws_(Predicate_Logic)]).
In JIRA subjects and commit messages, please upper-case SQL keywords (e.g.
"ALL"). It makes them much clearer.
> When All sub-query contains 3-valued logic, Calcite returns wrong result

> In 3-valued logic, as we know:
> {code:java}
> unknow and false => false
> {code}
> So the SQL:
> {code:java}
> select 1 = all(null, 2) should return false but is null.
> {code}
> {code:java}
> select 1 = all(null, 2, 1) should return false but is true.
> {code}
