> 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).
