Julian Hyde updated CALCITE-4210:
---------------------------------
Description:
SqlToRelConverter does not correctly expand a sub-query in an ON clause.
Aggregation is dropped during decorrelation.
{code:java}
SELECT "employee"."department_id", "employee"."salary"
FROM "department"
LEFT JOIN "employee" ON "employee"."salary" = (
SELECT max("employee"."salary")
FROM "employee"
WHERE "employee"."department_id" = "department"."department_id"
)
{code}
{code:java}
LogicalProject(department_id=[$9], salary=[$13])
LogicalJoin(condition=[=($13, $0)], joinType=[left])
LogicalTableScan(table=[[foodmart, department]])
LogicalTableScan(table=[[foodmart, employee]]){code}
This may be related to CALCITE-4206.
