Yuming Wang updated SPARK-28064:
--------------------------------
Issue Type: Sub-task (was: Task)
Parent: SPARK-27764
> Order by does not accept a call to rank()
> -----------------------------------------
>
> 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.
