Xingcan Cui updated FLINK-34633:
--------------------------------
    Description: 
It seems that the current planner doesn't support using UNNEST on array 
constants.(x)
{code:java}
SELECT * FROM UNNEST(ARRAY[1,2,3]);{code}
 
The following query can't be compiled.(x)
{code:java}
SELECT * FROM (VALUES('a')) CROSS JOIN UNNEST(ARRAY[1, 2, 3]){code}
 
The rewritten version works. (/)
{code:java}
SELECT * FROM (SELECT *, ARRAY[1,2,3] AS A FROM (VALUES('a'))) CROSS JOIN 
UNNEST(A){code}
