[jira] [Created] (CALCITE-3296) Decorrelator gives empty result after decorrelating sort rel with null offset and fetch

             Summary: Decorrelator gives empty result after decorrelating sort rel with null offset and fetch
                 Key: CALCITE-3296
                 URL: https://issues.apache.org/jira/browse/CALCITE-3296
             Project: Calcite
          Issue Type: Bug
            Reporter: Juhwan Kim
            Assignee: Juhwan Kim


It seems like I introduced a bug with the recent decorrelator patch. Sort rel with null offset and fetch would end up becoming an empty value since decorrelator would call sortLimit builder with 0 limit and 0 offset. It should pass negative values to builder when values are null.
