---------------------------------------
Summary: window functions that involve TIME columns generate wrong
results
Key: DRILL-3281
URL: https://issues.apache.org/jira/browse/DRILL-3281
Project: Apache Drill
Issue Type: Sub-task
Reporter: Deneche A. Hakim
Assignee: Deneche A. Hakim
Computing a MAX or MIN of a TIME column using the OVER clause seem to generate
wrong results compared to Postgres. Example of such queries:
{noformat}
SELECT MIN(cast( columns[8] as TIME )) OVER(PARTITION BY cast( columns[2] as
CHAR(2)) ORDER BY cast( columns[0] as INT )) FROM `allData.csv`;
{noformat}
SELECT MAX(cast( columns[8] as TIME )) OVER(PARTITION BY cast( columns[2] as
CHAR(2)) ORDER BY cast( columns[0] as INT )) FROM `allData.csv`;
{noformat}
{noformat}
