Subject [jira] [Created] (HIVE-3194) implement the JDBC canonical/ISO-SQL 2012 scalar functions
Date Sun, 24 Jun 2012 18:22:42 GMT
N Campbell created HIVE-3194:
--------------------------------

             Summary: implement the JDBC canonical/ISO-SQL 2012 scalar functions
                 Key: HIVE-3194
                 URL: https://issues.apache.org/jira/browse/HIVE-3194
             Project: Hive
          Issue Type: Improvement
    Affects Versions: 0.8.0
            Reporter: N Campbell


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).
