---------------------------------------

             Summary: Calcite TO_CHAR function is incorrectly marked as 
returning a non-nullable result
                 Key: CALCITE-6572
                 URL: https://issues.apache.org/jira/browse/CALCITE-6572
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.37.0
            Reporter: Claude Brisson


We would expect the result of TO_CHAR(<date or timestamp>, <format>) to be 
nullable, while it is not for now.
