> Expression IDs shouldn't be present in grouping expressions when using
> grouping sets

> Key: SPARK-52007
> URL: https://issues.apache.org/jira/browse/SPARK-52007
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.1.0
> Reporter: Mihailo Aleksic
> Assignee: Mihailo Aleksic
> Priority: Major
> Labels: pull-request-available
> Fix For: 4.1.0
>
>
> In current version following query works:
> {code:java}
> select * from values(1,2) group by grouping sets (col1,col2,col1+col2) order
> by `(col1#x + col2#y)`
> {code}
> where #x and #y are expression IDs generated for related attributes. This
> isn't right as it leads to nondeterministic behavior (queries that pass would
> fail next time). In this issue I propose that we fix that.
