[jira] [Created] (DRILL-3292) SUM(constant) OVER(...) returns wrong
results
Deneche A. Hakim created DRILL-3292:
---------------------------------------
Summary: SUM(constant) OVER(...) returns wrong results
Key: DRILL-3292
URL: https://issues.apache.org/jira/browse/DRILL-3292
Project: Apache Drill
Issue Type: Bug
Components: Execution - Relational Operators, Query Planning & Optimization
Affects Versions: 1.0.0
Reporter: Deneche A. Hakim
Assignee: Deneche A. Hakim
The following query returns wrong results:
{noformat}
0: jdbc:drill:> select sum(1) over w sum1, sum(5) over w sum5 from cp.`employee.json` where position_id = 2 window w as (partition by position_id);
+-------+-------+
| sum1 | sum5 |
+-------+-------+
| 6 | 6 |
| 6 | 6 |
| 6 | 6 |
| 6 | 6 |
| 6 | 6 |
| 6 | 6 |
+-------+-------+
{noformat}
The second column should display 30 (5 x 6) instead of 6.
Here is the plan for the query:
{noformat}
00-00 Screen
00-01 Project(sum1=[$0], sum5=[$1])
00-02 Project(sum1=[$0], sum5=[$1])
00-03 Project($0=[$1], $1=[$2])
00-04 Window(window#0=[window(partition {0} order by [] range between UNBOUNDED PRECEDING and UNBOUNDED FOLLOWING aggs [SUM($1), SUM($2)])])
00-05 SelectionVectorRemover
00-06 Sort(sort0=[$0], dir0=[ASC])
00-07 Filter(condition=[=($0, 2)])
00-08 Scan(groupscan=[EasyGroupScan [selectionRoot=/employee.json, numFiles=1, columns=[`position_id`], files=[classpath:/employee.json]]])
{noformat}
