Caican Cai created CALCITE-6409:
-----------------------------------
Summary: Character types and Boolean types are comparable
Key: CALCITE-6409
URL: https://issues.apache.org/jira/browse/CALCITE-6409
Project: Calcite
Issue Type: Improvement
Components: core
Affects Versions: 1.37.0
Reporter: Caican Cai
Fix For: 1.38.0
In the SameOperandTypeChecker method, the char type and the boolean type are
comparable because of the call to the isComparable method.
Comparability of char types and boolean types returns true in the isComparable
method.
However, char types and Boolean types in Spark are incomparable. Does Calcite
have fixed standards here?
