Vladimir Sitnikov commented on CALCITE-4398:
--------------------------------------------
{{?0.int1}} is nullable, so {{>=(?0.int1, 0)}} could be {{null}}.
> RexSimplify introduces cast(nullable as nonnull)
> ------------------------------------------------

> Key: CALCITE-4398
> URL: https://issues.apache.org/jira/browse/CALCITE-4398
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.26.0
> Reporter: Vladimir Sitnikov
> Priority: Major
>
> {noformat}
> isNotNull(case_(case_(trueLiteral, isFalse(lt(vInt(1), literal(0))),
> trueLiteral), trueLiteral, falseLiteral))
> {noformat}
> is optimized to
> {noformat}IS NOT NULL(CAST(>=(?0.int1, 0)):BOOLEAN NOT NULL){noformat}
> which looks strange, since it casts nullable value to a non-null type.
