> 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;
