[jira] [Updated] (DRILL-2376) UNION ALL on Aggregates with GROUP BY
returns incomplete results
[ https://issues.apache.org/jira/browse/DRILL-2376?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Abhishek Girish updated DRILL-2376:
-----------------------------------
Description:
The following query fails to execute:
{code:sql}
select x
from
(SELECT Sum(ss_ext_sales_price) x
FROM store_sales
UNION ALL
SELECT Sum(cs_ext_sales_price) x
FROM catalog_sales) tmp
GROUP BY x;
Results from Drill:
+------------+
| x |
+------------+
| 3658019159.35 |
+------------+
1 row selected (3.474 seconds)
Results from Postgres:
x
---------------
5265207074.51
3658019159.35
(2 rows)
{code}
Removing GROUP BY returns the right results:
{code:sql}
select x
from
(SELECT Sum(ss_ext_sales_price) x
FROM store_sales
UNION ALL
SELECT Sum(cs_ext_sales_price) x
FROM catalog_sales) tmp;
Results from Drill:
+------------+
| x |
+------------+
| 5265207074.51 |
| 3658019159.35 |
+------------+
{code}
