> Hive SQL does not support {{*ALTER FUNCTION*}} yet, we can refer to the {{*CREATE [OR REPLACE] FUNCTION*}} of [Spark|https://spark.apache.org/docs/3.1.2/sql-ref-syntax-ddl-create-function.html] to implement the alter function .
> {code:sql}
> CREATE [ TEMPORARY ] FUNCTION [ OR REPLACE ] [IF NOT EXISTS ]
>   [db_name.]function_name AS class_name
>   [USING JAR|FILE|ARCHIVE 'file_uri' [, JAR|FILE|ARCHIVE 'file_uri'] ];
> {code}
> * *OR REPLACE*
> If specified, the resources for the function are reloaded. This is mainly useful to pick up any changes made to the implementation of the function. This parameter is mutually exclusive to {{*IF NOT EXISTS*}} and can not be specified together.
