             Summary: 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: Task
          Components: SQL
    Affects Versions: 3.0.0
            Reporter: Dylan Guedes


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.
