> Fix Aggregate bug in RewriteWithExpression
> ------------------------------------------
>
> Key: SPARK-47839
> URL: https://issues.apache.org/jira/browse/SPARK-47839
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 4.0.0
> Reporter: Kelvin Jiang
> Priority: Major
> Labels: pull-request-available
>
> The following query will fail:
> ```
> SELECT NULLIF(id + 1, 1)
> from range(10)
> group by id
> ```
> This is because `NullIf` gets rewritten to `With`, then
> `RewriteWithExpression` tries to pull `id + 1` out of the aggregate,
> resulting in an invalid plan.
