HIVE-4144 Add "select database()" command to show the current database
A recent hive-user mailing list conversation asked about having a command to
show the current database.

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.
