> Prevent Multiple SortOrders for an Expression
> ---------------------------------------------
>
> Key: SPARK-46349
> URL: https://issues.apache.org/jira/browse/SPARK-46349
> Project: Spark
> Issue Type: Bug
> Components: PySpark, SQL
> Affects Versions: 4.0.0
> Reporter: Majid Hajiheidari
> Priority: Minor
>
> Hello everyone,
> This is my first contribution to the project. I welcome any feedback and
> edits to improve this pull request.Currently, it's possible to create
> redundant sort expressions in both Scala and Python APIs, leading to
> potentially incorrect and confusing SQL statements. For example:
> Scala:
> {code:java}
> spark.range(10).orderBy($"id".desc.asc).show(){code}
> Python:
> {code:java}
> spark.range(10).orderBy(f.desc('id'), ascending=False).show(){code}
>
> Such usage generates SQL like order by id DESC NULLS LAST DESC NULLS LAST,
> causing non-descriptive error messages.
>
> I look forward to your feedback and thank you for considering this
> contribution.
