Bharathkrishna Guruvayoor Murali commented on HIVE-19370: --------------------------------------------------------- I do not think this is a bug, as it is mentioned in the add_months description in [LanguageManual UDF|https://cwiki.apache.org/confluence/display/Hive/LanguageManual+UDF] : {quote}start_date is a string, date or timestamp. num_months is an integer. The time part of start_date is ignored. {quote} > Issue: ADD Months function on timestamp datatype fields in hive > --------------------------------------------------------------- > > Key: HIVE-19370 > URL: https://issues.apache.org/jira/browse/HIVE-19370 > Project: Hive > Issue Type: Bug > Reporter: Amit Chauhan > Assignee: Bharathkrishna Guruvayoor Murali > Priority: Major > > *Issue:* > while using ADD_Months function on a timestamp datatype column the output > omits the time part[HH:MM:SS] part from output. > which should not be the case. > *query:* EMAIL_FAILURE_DTMZ is of datatype timestamp in hive. > hive> select CUSTOMER_ID,EMAIL_FAILURE_DTMZ,ADD_MONTHS (EMAIL_FAILURE_DTMZ , > 1) from TABLE1 where CUSTOMER_ID=125674937; > OK > 125674937 2015-12-09 12:25:53 2016-01-09 > *hiver version :* > hive> !hive --version; > Hive 1.2.1000.2.5.6.0-40 > > can you please help if somehow I can get below as output: > > 125674937 2015-12-09 12:25:53 2016-01-09 12:25:53 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
