MySQL select formatted date from millisecond field

Try using the FROM_UNIXTIME function like this as given in the manual

SELECT FROM_UNIXTIME(1196440219); -> '2007-11-30 10:30:19'

You could also use formatting like this

mysql> SELECT FROM_UNIXTIME(UNIX_TIMESTAMP(),    ->                      '%Y %D %M %h:%i:%s %x');    -> '2007 30th November 10:30:59 2007'

If you want to get the microsecond from a field, use %f,

select FROM_UNIXTIME(DATE_COLUMN/1000,'%Y-%M-%d %H:%i:%s %f') from TABLE_NAME;+-------------------------------------------------------+| FROM_UNIXTIME(CREATETIME/1000,'%Y-%M-%d %H:%i:%s %f') |+-------------------------------------------------------+| 2016-March-18 16:02:54 342000                         |+-------------------------------------------------------+
