>
> The Hive driver does not return any canonical JDBC scalar functions (per JDBC
> 3.0/4.0). Similarly, while Hive has various 'similar' scalar functions their
> signature (name etc) is not the same as ISO-SQL equivalent. It would be
> better for portable dynamic SQL applications to see more alignment by Hive
> etc to both standards. In some cases it is small syntactic changes/tweaks
> (i.e. see mod, substring etc).
