-------------------------------------------
Summary: Predicate Pull up above Project enhancement (was: Predicate Pull
up on Project enhancement)
> Predicate Pull up above Project enhancement
> -------------------------------------------
>
> Key: CALCITE-993
> URL: https://issues.apache.org/jira/browse/CALCITE-993
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.5.0
> Reporter: Laljo John Pullokkaran
> Assignee: Laljo John Pullokkaran
>
> Predicate Pull up on Project can also pull up deterministic functions whose
> arguments are all literals.
> Ex: select r1.x from (select cast('10' as int) as x, y from r1 where y<10)r1
> join r2 on r1.x=r2.x;
> Currently deterministic functions involving constants are ignored which
> results in missed transitive inference.
