Subject [jira] [Created] (DRILL-3359) Drill should throw and error when window function defined using WINDOW AS uses ROWS UNBOUNDED PRECEDING
Date Wed, 24 Jun 2015 20:41:05 GMT
Deneche A. Hakim created DRILL-3359:
---------------------------------------

             Summary: Drill should throw and error when window function defined using WINDOW
AS uses ROWS UNBOUNDED PRECEDING
                 Key: DRILL-3359
                 URL: https://issues.apache.org/jira/browse/DRILL-3359
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Deneche A. Hakim
            Assignee: Sean Hsuan-Yi Chu


as part of DRILL-3188, the following query is not supported and Drill displays the proper
error message:
{noformat}
0: jdbc:drill:zk=local> select sum(salary) over(partition by position_id order by salary
rows unbounded preceding) from cp.`employee.json` limit 20;
Error: UNSUPPORTED_OPERATION ERROR: This type of window frame is currently not supported 
See Apache Drill JIRA: DRILL-3188
{noformat}

But when defining the same window using a WINDOW AS, Drill doesn't throw any error:
{noformat}
0: jdbc:drill:zk=local> select sum(salary) over w from cp.`employee.json` window w as (partition
by position_id order by salary rows unbounded preceding) limit 20;

The results are, of course, incorrect
