--------------------------------------

             Summary: Failed to materialize when the aggregate function uses group key
                 Key: CALCITE-3160
                 URL: https://issues.apache.org/jira/browse/CALCITE-3160
             Project: Calcite
          Issue Type: Bug
            Reporter: Haisheng Yuan


Repro:
{code:java}
@Test public void testAggregateGroupSetsRollUp() {
    checkMaterialize(
        "select \"empid\", \"deptno\", count(*) as c, sum(\"empid\") as s from \"emps\" "
            + "group by \"empid\", \"deptno\"",
        "select count(*) + 1 as c,  \"deptno\" from \"emps\" group by cube(\"empid\",\"deptno\")",
        HR_FKUK_MODEL,
        CalciteAssert.checkResultContains(
            "EnumerableCalc(expr#0..2=[{inputs}], expr#3=[1], "
                + "expr#4=[+($t2, $t3)], C=[$t4], deptno=[$t1])\n"
                + "  EnumerableAggregate(group=[{0, 1}], groups=[[{0, 1}, {0}, {1}, {}]], agg#0=[$SUM0($2)])\n"
                + "    EnumerableTableScan(table=[[hr, m0]])"));
  }
{code}

Note that if we change sum(\"empid\") to sum("salary"), it can materialize successfully.
