-------------------------------------
Summary: RexCall's Monotonicity is not considered in determining a
Calc's collation
Key: CALCITE-3151
URL: https://issues.apache.org/jira/browse/CALCITE-3151
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.19.0
Reporter: Zhenghua Gao
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).
