----------------------------------------
Summary: Projecting '*' returns all nulls when we have flatten in
a filter and order by
Key: DRILL-2228
URL: https://issues.apache.org/jira/browse/DRILL-2228
Project: Apache Drill
Issue Type: Bug
Components: Functions - Drill
Reporter: Rahul Challapalli
Assignee: Jason Altekruse
git.commit.id.abbrev=3d863b5
The below query returns all nulls currently :
{code}
0: jdbc:drill:schema=dfs_eea> select * from `data.json` where 2 in (select
flatten(lst_lst[1]) from `data.json`) order by flatten(lst_lst[1]);
+------------+
| * |
+------------+
| null |
| null |
| null |
| null |
| null |
| null |
| null |
| null |
| null |
| null |
+------------+
{code}
There seems to be another issue here since the no of records returned also does
not look right. I will raise a separate JIRA for that.
The issue goes away, if we do an order by without the flatten. Below query works
{code}
select * from `data.json` where 2 in (select flatten(lst_lst[1]) from
`data.json`) order by uid;
{code}
Attached the data files
