Chunwei Lei updated CALCITE-3004:
---------------------------------
Description:
*1. Test case for ProjectSetOpTransposeRule:*
{code:sql}
select count(sal) over () from (select * from emp e1 union all select * from
emp e2)
{code}
Plan:
{code:java}
LogicalUnion(all=[true])
LogicalProject(EXPR$0=[COUNT($5) OVER (RANGE BETWEEN UNBOUNDED PRECEDING AND
UNBOUNDED FOLLOWING)])
LogicalProject(EMPNO=[$0], ENAME=[$1], JOB=[$2], MGR=[$3], HIREDATE=[$4],
SAL=[$5], COMM=[$6], DEPTNO=[$7], SLACKER=[$8])

UNBOUNDED FOLLOWING)])

SAL=[$5], COMM=[$6], DEPTNO=[$7], SLACKER=[$8])
LogicalTableScan(table=[[CATALOG, SALES, EMP]])
{code}
Should be:

LogicalTableScan(table=[[CATALOG, SALES, EMP]]){code}
*2. Test case for ProjectCorrelateTransposeRule:*
{code:sql}
select t2.empno, sum(t1.deptno) over () from DEPT_NESTED as t1,
unnest(t1.employees) as t2
{code}
*Plan: Will cause infinitely loop due to RexOver is pushed down*
Should be:
{code:java}
LogicalProject(EMPNO=[$2], EXPR$1=[SUM($0) OVER (RANGE BETWEEN UNBOUNDED
PRECEDING AND UNBOUNDED FOLLOWING)])
LogicalCorrelate(correlation=[$cor1], joinType=[inner], requiredColumns=[{1}])
LogicalProject(DEPTNO=[$0], EMPLOYEES=[$3])
LogicalTableScan(table=[[CATALOG, SALES, DEPT_NESTED]])
LogicalProject(EMPNO=[$0])
Uncollect
LogicalProject(EMPLOYEES=[$cor1.EMPLOYEES])
LogicalValues(tuples=[[{ 0 }]]){code}
