Sean Hsuan-Yi Chu updated DRILL-3183:
-------------------------------------
Summary: Query that uses window functions returns NPE (was: When Group By
clause is present, the argument in window function should not refer to any
column outside Group By)
> Query that uses window functions returns NPE
> --------------------------------------------
>
> Key: DRILL-3183
> URL: https://issues.apache.org/jira/browse/DRILL-3183
> Project: Apache Drill
> Issue Type: Bug
> Components: Query Planning & Optimization
> Affects Versions: 1.0.0
> Environment: faec150598840c40827e6493992d81209aa936da
> Reporter: Khurram Faraaz
> Assignee: Sean Hsuan-Yi Chu
> Labels: window_function
> Fix For: 1.1.0
>
>
> Test was run on 4 node cluster on CentOS. We see NPE for a query that uses
> window functions. Data was from CSV file (headers were ignored).
> To enable window functions,
> alter session set `window.enable`=true;
> These two queries work
> {code}
> SELECT count(salary) OVER w, count(salary) OVER w FROM cp.`employee.json` t
> WINDOW w AS (PARTITION BY store_id ORDER BY position_id DESC);
> SELECT count(columns[0]) OVER(PARTITION BY columns[1] ORDER BY columns[0]
> DESC), count(columns[0]) OVER(PARTITION BY columns[1] ORDER BY columns[0]
> DESC) FROM `airports.csv`;
> {code}
> These two queries do not work and in the second query we see a NPE
> {code}
> 0: jdbc:drill:schema=dfs.tmp> SELECT count(*) OVER w, count(*) OVER w FROM
> `airports.csv` WINDOW w AS (PARTITION BY columns[1] ORDER BY columns[0] DESC);
> Error: PARSE ERROR: From line 1, column 87 to line 1, column 93: Table
> 'columns' not found
