Hive - month and year from timestamp column

I'd prefer to use Hive date_format() (as of Hive 1.2.0). It support Java SimpleDateFormat patterns.

date_format() accepts date/timestamp/string. So your final query will be

select date_format(upd_gmt_ts,'yyyyMM') from abc.test;

Edit:

SimpleDateFormat acceptable patterns examples.

You can use CONCAT and FROM_UNIXTIME like below:

SELECT CONCAT(YEAR(FROM_UNIXTIME(1468215093)), MONTH(FROM_UNIXTIME(1468215093))) AS YEAR_MONTH

In your query:

SELECT CONCAT(YEAR(FROM_UNIXTIME(upd_gmt_ts)), MONTH(FROM_UNIXTIME(upd_gmt_ts))) AS YEAR_MONTHFROM abc.test;

date hadoop hive sql-timestamp

Please use the following query

SELECT YEAR(FROM_UNIXTIME(unix_timestamp()))*100 + MONTH(FROM_UNIXTIME(unix_timestamp()))
