Subject [jira] [Commented] (HIVE-4144) Add "select database()" command to show the current database
Date Thu, 04 Jul 2013 18:03:48 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4144?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13700265#comment-13700265

Edward Capriolo commented on HIVE-4144:
---------------------------------------

Navis. This is cool. I will review this soon. I did notice that there is already a Dummy input
format like yours that was added to hive a while back. I think it was added to support queries
only on meta-data. In any case we probably do not need two dummy Input formats in the project.
