>                 Key: SPARK-28064
>                 URL: https://issues.apache.org/jira/browse/SPARK-28064
>             Project: Spark
>          Issue Type: Sub-task
>          Components: SQL
>    Affects Versions: 3.0.0
>            Reporter: Dylan Guedes
>            Priority: Major

> Currently in Spark, we can't use a call to `rank()` in a order by; we need to first rename the rank column to, for instance, `r` and then, use `order by r`. For example:
>  This does not work:
> {code:sql}
>  SELECT depname, empno, salary, rank() OVER w FROM empsalary WINDOW w AS (PARTITION BY depname ORDER BY salary) ORDER BY rank() OVER w;
> {code}
> However, this one does:
> {code:sql}
>  SELECT depname, empno, salary, rank() OVER w as r FROM empsalary WINDOW w AS (PARTITION BY depname ORDER BY salary) ORDER BY r;
> {code}
> By the way, I took this one from Postgres behavior: postgres accept both ways.
