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

             Summary: SqlRun: Match output regardless of order if ORDER BY not present
                 Key: OPTIQ-316
                 URL: https://issues.apache.org/jira/browse/OPTIQ-316
             Project: optiq
          Issue Type: Bug
            Reporter: Julian Hyde
            Assignee: Julian Hyde


If ORDER BY is not present, a compliant implementation may return rows in any order. SqlRun should detect this, output the rows in the original order, not the actual order.

This feature makes it much easier to handle unsorted data. The previous workaround, adding an ORDER BY clause, may trigger a different execution path and mask bugs. And it was common to forget an ORDER BY and have to go back to add the ORDER BY and correct the data some weeks later.
