Haisheng Yuan created CALCITE-3160:
--------------------------------------
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.
