Subject [jira] [Updated] (SPARK-12789) Support order by position in SQL
Date Thu, 17 Mar 2016 04:50:33 GMT

     [ https://issues.apache.org/jira/browse/SPARK-12789?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Reynold Xin updated SPARK-12789:
--------------------------------
    Description: 
This is to support order by position in SQL, e.g.

{noformat}
select c1, c2, c3 from tbl order by 1 desc, 3
{noformat}

should be equivalent to

{noformat}
select c1, c2, c3 from tbl order by c1 desc, c3
{noformat}

We only convert integer literals (not foldable expressions).

We should make sure this also works with select *.

This should be controlled by config option spark.sql.orderByOrdinal.
