Aman Sinha created DRILL-395:
--------------------------------
Summary: ORDER-BY on an expression gives CannotPlanException
Key: DRILL-395
URL: https://issues.apache.org/jira/browse/DRILL-395
Project: Apache Drill
Issue Type: Bug
Reporter: Aman Sinha
The following query works ok.. it has an expression in the SELECT list and we
are doing an ORDER-BY on that expression:
select N_NATIONKEY + 1 from dfs.`/tmp/parquet/nation.parquet` order by 1;
However, the following query which puts the same expression in the ORDER-BY
clause throws an error:
select N_NATIONKEY from dfs.`/tmp/parquet/nation.parquet` order by N_NATIONKEY
+ 1;
Error 2935dcfa-2b22-45ea-b74f-05d0133a0608: Failure while parsing sql.
