[jira] [Created] (DRILL-2094) Drill has problems with reading json
fields when used in a subquery
Rahul Challapalli created DRILL-2094:
----------------------------------------
Summary: Drill has problems with reading json fields when used in a subquery
Key: DRILL-2094
URL: https://issues.apache.org/jira/browse/DRILL-2094
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Reporter: Rahul Challapalli
Assignee: Jinfeng Ni
git.commit.id.abbrev=3e33880
Data Set :
{code}
{
"id" : 1,
"list" : [1,2]
}
{code}
The below query works
{code}
0: jdbc:drill:schema=dfs.drillTestDir> select id from `temp1.json` order by list[0];
+------------+
| id |
+------------+
| 1 |
+------------+
1 row selected (0.146 seconds)
{code}
However when I used the same exact query as part of a sub-query, I get an error from drill
{code}
0: jdbc:drill:schema=dfs.drillTestDir> select s.id from (select id from `temp1.json` order by list[0]) s;
Query failed: SqlValidatorException: Table 'list' not found
Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}
Explain plan also does not work and it returns the same problem
