In [FLINK-12999|https://issues.apache.org/jira/browse/FLINK-12999] I found a case that the planner can't generate a valid execution plan for a sample query: SELECT UUID() FROM (VALUES(1, 2, 3)) T(a, b, c) I made an investigation and found the root case was: RexCall's Monotonicity is not considered in determining a Calc's collation( should do the same as Project). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
