> Filter predicates aren't inferred while using dynamic star in subquery
> ----------------------------------------------------------------------
>
> Key: CALCITE-2274
> URL: https://issues.apache.org/jira/browse/CALCITE-2274
> Project: Calcite
> Issue Type: Improvement
> Affects Versions: 1.16.0
> Reporter: Vitalii Diravka
> Assignee: Zhen Chen
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.42.0
>
>
> Filter predicates are not inferred (in RelMdPredicates#getPredicates(), for
> example by using
> JoinPushTransitivePredicatesRule), in case when above LogicalProject has
> dynamic star.
> Query example:
> {code:java}
> SELECT * FROM sales.emp d JOIN
> (SELECT * FROM sales.emp WHERE deptno = 4) e
> ON e.deptno = d.deptno
> {code}
> By using JoinPushTransitivePredicatesRule the expected result is:
> {code:java}
> LogicalProject(**=[$0])
> LogicalJoin(condition=[=($16, $7)], joinType=[inner])
> LogicalFilter(condition=[=($7, 4)])
> LogicalTableScan(table=[[CATALOG, SALES, EMP]])
> LogicalProject(**=[$0])
> LogicalFilter(condition=[=($7, 4)])
> LogicalTableScan(table=[[CATALOG, SALES, EMP]])
> {code}
> and actual result:
> {code:java}
> LogicalProject(**=[$0])
> LogicalJoin(condition=[=($16, $7)], joinType=[inner])
> LogicalTableScan(table=[[CATALOG, SALES, EMP]])
> LogicalProject(**=[$0])
> LogicalFilter(condition=[=($7, 4)])
> LogicalTableScan(table=[[CATALOG, SALES, EMP]])
> {code}
