Date Sun, 24 Jun 2012 23:41:42 GMT


Carl Steinbach updated HIVE-3194:

    Component/s: UDF
> implement the JDBC canonical/ISO-SQL 2012 scalar functions
> ----------------------------------------------------------
>                 Key: HIVE-3194
>                 URL:
>             Project: Hive
>          Issue Type: Improvement
>          Components: JDBC, SQL, UDF
>    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).
