Date Tue, 26 May 2015 21:58:18 GMT
Victoria Markman created DRILL-3189:
---------------------------------------

             Summary: Disable ALLOW PARTIAL/DISALLOW PARTIAL in window function grammar
                 Key: DRILL-3189
                 URL: https://issues.apache.org/jira/browse/DRILL-3189
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
    Affects Versions: 1.0.0
            Reporter: Victoria Markman
            Assignee: Jinfeng Ni
            Priority: Critical


It does not seem to be implemented on the drill side. Looks like Calcite specific grammar.
Don't see it SQL Standard.

Looks like wrong result:
{code}
0: jdbc:drill:schema=dfs> select a2, sum(a2) over(partition by a2 order by a2 rows between
1 preceding and 1 following disallow partial) from t2 order by a2;
+-----+---------+

+-----+---------+
| 0   | null    |
