xiejiajun updated CALCITE-4665:
-------------------------------
Description:
{code:java}
builder.scan("EMP")
.aggregate(builder.groupKey(0, 1, 7),
builder.aggregateCall(SqlStdOperatorTable.COUNT,
builder.field("JOB")).as("job_num"))
.aggregate(
builder.groupKey(ImmutableBitSet.of(0, 1, 2),
(Iterable<ImmutableBitSet>)
ImmutableList.of(ImmutableBitSet.of(0, 1))))
// GROUP BY 0,1,2 GROUPING SETS((0, 1))
.build();
{code}
Before fix:
{code:java}
LogicalProject(EMPNO=[$0], ENAME=[$1], DEPTNO=[$2])
LogicalAggregate(group=[{0, 1, 7}], job_num=[COUNT($2)])
LogicalTableScan(table=[[scott, EMP]])
{code}
After fix:
{code:java}
LogicalAggregate(group=[{0, 1, 2}], groups=[[{0, 1}]])
LogicalAggregate(group=[{0, 1, 7}], job_num=[COUNT($2)])
LogicalTableScan(table=[[scott, EMP]]){code}
I use calcite For example:
{code:java}
SELECT
t.ID, t.NAME, nvl(t.AGE, 0) T_AGE
FROM
(SELECT u.ID, u.NAME, u.AGE
FROM USERS u
GROUP BY u.ID, u.NAME, u.AGE
) t
GROUP BY t.ID, t.NAME, t.AGE
GROUPING SETS(
(t.ID, t.NAME),
(t.ID, t.NAME, t.AGE)
)
{code}
will be
{code:java}
SELECT u.ID, u.NAME, u.AGE
FROM USERS u
GROUP BY u.ID, u.NAME, u.AGE
{code}
groupings set are missing
was:
For example:
{code:java}
SELECT
t.ID, t.NAME, count(t.AGE) T_AGE
FROM
(SELECT u.ID, u.NAME, u.AGE
FROM USERS u
GROUP BY u.ID, u.NAME, u.AGE
) t
GROUP BY t.ID, t.NAME, t.AGE
GROUPING SETS(
(t.ID, t.NAME),
(t.ID, t.NAME, t.AGE)
)
{code}
will be
{code}
SELECT u.ID, u.NAME, u.AGE
FROM USERS u
GROUP BY u.ID, u.NAME, u.AGE
{code}
groupings set are missing
> When group by are same as sub-query, grouping sets are missing
