------------------------------------
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.
