## Which issue does this PR close? Related to #12733 We found another bug for aliased now() columns. ## Rationale for this change See the reproducer in the [first commit](https://github.com/apache/datafusion/commit/47f2a927b2ae3850ed8c0c00a3e967762593f27a). Both of the next two commits are required for the fix. ## What changes are included in this PR? `get_field_metadata` should handle aliased columns. Also, the `now()` udf is not nullable. ## Are these changes tested? Yes. ## Are there any user-facing changes? Not really. Only that the now() udf will return not-nullable (instead of the default impl). -- This is an automated message from the Apache Git Service.
