> Key: SPARK-43980
> URL: https://issues.apache.org/jira/browse/SPARK-43980
> Project: Spark
> Issue Type: New Feature
> Components: SQL
> Affects Versions: 3.4.0
> Reporter: Yash Kothari
> Priority: Major
>
> I'm looking for a way to incorporate the {{select * except(col1, ...)}}
> clause provided by Databricks into my workflow. I don't use Databricks and
> would like to introduce this {{select except}} clause either as a
> spark-package or by contributing a change to Spark.
> However, I'm unsure about how to begin this process and would appreciate any
> guidance from the community.

> Thank you for your assistance.
