> Support order by ordinal in SQL

>                 Key: SPARK-12789
>                 URL: https://issues.apache.org/jira/browse/SPARK-12789
>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>            Reporter: zhichao-li
>            Priority: Minor
>
> 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.
