libopeng updated CALCITE-5568:
------------------------------
Description:
Decorrelate will fail. If the RelNode tree has LogicalValues
case:
{code:java}
SELECT
( SELECT COUNT(tbl2.deptno) FROM emp AS tbl2 WHERE tbl1.deptno = tbl2.deptno )
AS c0,
( SELECT 1 ) AS c1
FROM emp AS tbl1 {code}
after decorrelate
(org.apache.calcite.sql2rel.RelDecorrelator#decorrelateQuery(org.apache.calcite.rel.RelNode,
org.apache.calcite.tools.RelBuilder))
{code:java}
LogicalProject(C0=[$9], C1=[$10])
LogicalJoin(condition=[true], joinType=[left])
LogicalProject(EMPNO=[$0], ENAME=[$1], JOB=[$2], MGR=[$3], HIREDATE=[$4],
SAL=[$5], COMM=[$6], DEPTNO=[$7], SLACKER=[$8], EXPR$0=[CASE(IS NULL($9),
0:BIGINT, $9)])
LogicalCorrelate(correlation=[$cor0], joinType=[left],
requiredColumns=[{7}])
LogicalTableScan(table=[[CATALOG, SALES, EMP]])
LogicalAggregate(group=[{}], EXPR$0=[COUNT()])
LogicalProject(DEPTNO=[$7])
LogicalFilter(condition=[=($cor0.DEPTNO, $7)])
LogicalTableScan(table=[[CATALOG, SALES, EMP]])
LogicalAggregate(group=[{}], agg#0=[SINGLE_VALUE($0)])
LogicalValues(tuples=[[{ 1 }]]){code}
LogicalCorrelate will not be processed when the RelNode tree has LogicalValues

Is this as expected？
