Subject [jira] Updated: (HIVE-48) Support JDBC connections for interoperability between Hive and RDBMS
Date Fri, 02 Jan 2009 09:25:44 GMT

     [ https://issues.apache.org/jira/browse/HIVE-48?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Raghotham Murthy updated HIVE-48:

    Attachment: hive-48.6.patch

I have added functionality to getByte, getBoolean, getDouble, getFloat, getInt, getLong, getObject,
getShort, and changed getString to do a toString.

Also added a single test to test getInt. Right now, anything other than select * uses MetaDataTypedColumnSetSerDe
- so, the result schema has all columns as strings. Will add more tests to jdbc once we start
using DynamicSerDe for all queries.

> In many DW and BI systems, the data are stored in RDBMS for now such as oracle, mysql,
postgresql ... for reporting, charting and etc.
> It would be useful to be able to import data from RDBMS and export data to RDBMS using
JDBC connections.
> If Hive support JDBC connections, It wll be much easier to use 3rd party DW/BI tools.
