> Key: CALCITE-2147
> URL: https://issues.apache.org/jira/browse/CALCITE-2147
> Project: Calcite
> Issue Type: Bug
> Reporter: Vamshi
> Assignee: Julian Hyde
> Priority: Major
> Fix For: 1.16.0

>
> Problem description:
> When rollup or cube expressions are specified as input to grouping_sets ,then instead of handling the rollup or cube expression in LogicalAggregate operator they are handled in LogicalProject operator which is incorrect.
>
> Basically grouping_sets with rollup/cube expressions as input is not flattened into logical aggregate operator.
>
> Problem Test case:
> create table temp11(a integer, b integer);
> select a,b,count(*) from temp11 group by grouping sets(rollup(a,b),a,b,());
> Test Case output:
> {
> "rels": [
> {
> "id": "0",
> "relOp": "LogicalTableScan",
> "table": [
> "CATALOG",
> "temp11"
> ],
> "inputs": []
> },
