The backport PR: #28299 |

backport #28281 to 2.4 This backport has one difference: there is no `EXTRACT(... FROM ...)` SQL syntax in 2.4, so this PR just uses the common function call syntax. Closes#28299 from cloud-fan/pick. Authored-by: Wenchen Fan <wenchen@databricks.com> Signed-off-by: Dongjoon Hyun <dongjoon@apache.org>
