> Compute Current Time* expressions should be foldable
> ----------------------------------------------------

> Key: SPARK-47902
> URL: https://issues.apache.org/jira/browse/SPARK-47902
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 4.0.0
> Reporter: Aleksandar Tomic

> Priority: Major

> Fix For: 4.0.0

>
> Following PR - https://github.com/apache/spark/pull/44261 changed "compute
> current time" family of expressions to be unevaluable, given that these
> expressions are supposed to be replaced with literals by QO. Unevaluable
> implies that these expressions are not foldable, even though they will be
> replaced by literals.
> If these expressions were used in places that require constant folding (e.g.
> RAND()) new behavior would be to raise an error which is a regression
> comparing to behavior prior to spark 4.0.
