Niels Pardon commented on CALCITE-6261:
---------------------------------------
[~phanimahidhar] thanks for the PR I guess though I was already working on a PR
and thus had assigned the issue to me.
> RelBuilder.aggregate() field pruning does not use permuted field indices when
> used with force project and duplicate agg calls

> Key: CALCITE-6261
> URL: https://issues.apache.org/jira/browse/CALCITE-6261
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.35.0, 1.36.0
> Reporter: Niels Pardon
> Assignee: Niels Pardon
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.37.0
>
>
> We were running into issues with RelBuilder.aggregate() when we tried to
> upgrade our code from Calcite 1.32.0 to 1.36.0 and after some debugging it
> seems this is caused by changes introduced with CALCITE-4334.
> I was able to put together this test case for RelBuilderTest reproducing the
> issue:
> {code:java}
> @Test void testAggregateForceProject() {
> final Function<RelBuilder, RelBuilder> f1 = builder ->
> builder.scan("EMP")
> .project(
> ImmutableList.of(
> builder.field("EMPNO"),
> builder.field("ENAME"),
> builder.field("JOB"),
> builder.field("MGR"),
> builder.field("HIREDATE"),
> builder.field("SAL"),
> builder.field("COMM"),
> builder.field("DEPTNO")),
> ImmutableList.of(),
> true);
> final Function<RelBuilder, RelBuilder> f2 = builder ->
> builder.aggregate(
> builder.groupKey(builder.field("MGR")),
> builder.avg(false, "SALARY_AVG", builder.field("SAL")),
> builder.sum(false, "SALARY_SUM", builder.field("SAL")),
> builder.avg(false, "SALARY_MEAN", builder.field("SAL")));
> final String expected = ""
> + "LogicalProject(MGR=[$0], SALARY_AVG=[$1], SALARY_SUM=[$2],
> SALARY_MEAN=[$1])\n"
> + " LogicalAggregate(group=[{0}], SALARY_AVG=[AVG($1)],
> SALARY_SUM=[SUM($1)])\n"
> + " LogicalProject(MGR=[$3], SAL=[$5])\n"
> + " LogicalTableScan(table=[[scott, EMP]])\n";
> assertThat(f2.apply(f1.apply(createBuilder())).build(), hasTree(expected));
> } {code}
> With Calcite 1.36.0 you will get an AssertionError:

> RelBuilder still using the original groupSet and groupSets variables instead
