[jira] [Created] (SPARK-4487) Fix attribute reference resolution
error when using ORDER BY.
Kousuke Saruta created SPARK-4487:
-------------------------------------
Summary: Fix attribute reference resolution error when using ORDER BY.
Key: SPARK-4487
URL: https://issues.apache.org/jira/browse/SPARK-4487
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.2.0
Reporter: Kousuke Saruta
Priority: Critical
When we use ORDER BY clause, at first, attributes referenced by projection are resolved (1).
And then, attributes referenced at ORDER BY clause are resolved (2).
But when resolving attributes referenced at ORDER BY clause, the resolution result generated in (1) is discarded so for example, following query fails.
{code}
SELECT c1 + c2 FROM mytable ORDER BY c1;
{code}
The query above fails because when resolving the attribute reference 'c1', the resolution result of 'c2' is discarded.
