Summary: Missing ENUMERABLE Convention for
LogicalConditionalCorrelate
Key: CALCITE-7403

Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.41.0
Reporter: Zhen Chen
Using CoreQuidemTest2 to test the following SQL will result in an error.
{code:java}
# [CALCITE-6786] ANY/SOME operator yields multiple rows in correlated
queriesWITH tb as (select array(SELECT * FROM (VALUES (TRUE), (NULL)) as x(a))
as a)
SELECT TRUE IN (SELECT b FROM UNNEST(a) AS x1(b)) AS test FROM tb;
+------+
| TEST |
+------+
| true |
+------+
(1 row)
!ok {code}
Error message:
