Date Tue, 20 Oct 2015 18:30:27 GMT
Deneche A. Hakim created DRILL-3960:
---------------------------------------

             Summary: LEAD, LAG and NTILE should fail if ORDER BY clause is not present
                 Key: DRILL-3960
                 URL: https://issues.apache.org/jira/browse/DRILL-3960
             Project: Apache Drill
          Issue Type: Bug
          Components: SQL Parser
    Affects Versions: 1.2.0
            Reporter: Deneche A. Hakim


According to the SQL specification, LEAD, LAG and NTILE window functions require an ORDER
BY clause in the window definition. Drill should throw an error if these window functions
are used without an ORDER BY.
