Laurent Goujon created CALCITE-2344:
---------------------------------------

             Summary: Wrong constant reduction over windows function
                 Key: CALCITE-2344
                 URL: https://issues.apache.org/jira/browse/CALCITE-2344
             Project: Calcite
          Issue Type: Bug
            Reporter: Laurent Goujon
            Assignee: Laurent Goujon


{{RexUtil}} might incorrectly infer a IS NULL predicate would cause a reference over a window function to return null, but a window function type is never nullable.
