Krystal created DRILL-1302:
------------------------------
Summary: Order by using table.col in subquery fails with
ArrayIndexOutOfBoundsException
Key: DRILL-1302
URL: https://issues.apache.org/jira/browse/DRILL-1302
Project: Apache Drill
Issue Type: Bug
Components: Query Planning & Optimization
Reporter: Krystal
git.commit.id.abbrev=687b9b0
The following query runs successfully:
select cast(student.name as varchar(30)) name, cast(voter.registration as
varchar(20)) registration from voter full outer join student on (student.name =
voter.name) where student.age < 20 order by student.name;
If I put the above query in a sub-select, it fails:
0: jdbc:drill:schema=dfs> select tbl.name, tbl.registration from (select
cast(student.name as varchar(30)) name, cast(voter.registration as varchar(20))
registration from `dfs`.`default`.`./voter` voter full outer join
`dfs`.`default`.`./student` student on (student.name = voter.name) where
student.age < 20 order by student.name) tbl;
Query failed: Failure while parsing sql. -1
[fe42e70f-cf5b-4389-b879-5b1598ab887f]
Error: exception while executing query: Failure while trying to get next result
batch. (state=,code=0)
If I change the query using "order by name" without specifying the student
table, the query runs fine:
0: jdbc:drill:schema=dfs> select tbl.name, tbl.registration from (select
cast(student.name as varchar(30)) name, cast(voter.registration as varchar(20))
registration from `dfs`.`default`.`./voter` voter full outer join
`dfs`.`default`.`./student` student on (student.name = voter.name) where
student.age < 20 order by student.name) tbl;
The student.name in the order by clause should work.
