    [ https://issues.apache.org/jira/browse/HIVE-5810?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13993757#comment-13993757 ] 

Alan Gates commented on HIVE-5810:
----------------------------------

Hive already has DATE_ADD.  Why not add functionality to that rather than add a different function that does nearly the same thing?

> MySQL has ADDDATE(date,INTERVAL expr unit).
> Similarly in Hive we can have  (date,unit,expr). 
> Here Unit is DAY/Month/Year
> For example,
> add_date('2013-11-09','DAY',2) will return 2013-11-11.
> add_date('2013-11-09','Month',2) will return 2014-01-09.
> add_date('2013-11-09','Year',2) will return 2014-11-11.
