------------------------------------
Maybe we can use `insert as select` to achieve the same effect?
> current_user() is blocked from VALUES, but current_timestamp() is not

> URL: https://issues.apache.org/jira/browse/SPARK-42638
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 3.3.0
> Reporter: Serge Rielau
> Priority: Major
>
> VALUES(current_user());
> returns:
> cannot evaluate expression current_user() in inline table definition.; line 1
> pos 8
>
> The same with current_timestamp() works.
> It appears current_user() is recognized as non-deterministic. But it is
> constant within the statement, just like current_timestanmp().
> PS: It's not clear why we block non-deterministic functions to begin with....
