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

             Summary: Improve error message for cyclic views
                 Key: CALCITE-1900
                 URL: https://issues.apache.org/jira/browse/CALCITE-1900
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde
            Assignee: Julian Hyde


Detect that a view is cyclic (defined in terms of itself, or a view that depends on it) and give a better error message. Currently we get a stack overflow:
