Kelvin Jiang updated SPARK-47839:
---------------------------------
Description:
The following query will fail:
{code:SQL}
SELECT NULLIF(id + 1, 1)
from range(10)
group by id
{code}
This is because {{NullIf}} gets rewritten to {{With}}, then
{{RewriteWithExpression}} tries to pull common expression {{id + 1}} out of the
aggregate, resulting in an invalid plan.
was:
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.
