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? > create a function add_date as exists in mysql > ------------------------------------------------ > > Key: HIVE-5810 > URL: https://issues.apache.org/jira/browse/HIVE-5810 > Project: Hive > Issue Type: Improvement > Reporter: Anandha L Ranganathan > Assignee: Anandha L Ranganathan > Attachments: HIVE-5810.2.patch, HIVE-5810.patch > > Original Estimate: 40h > Remaining Estimate: 40h > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
