    Description

      A recent hive-user mailing list conversation asked about having a command to show the current database.
      http://mail-archives.apache.org/mod_mbox/hive-user/201303.mbox/%3CCAMGr+0i+CRY69m3id=DxthmUCWLf0NxpKMCtROb=uauH2vAHng@mail.gmail.com%3E

      MySQL seems to have a command to do so:

      select database();

      http://dev.mysql.com/doc/refman/5.0/en/information-functions.html#function_database

      We should look into having something similar in Hive.
