MySQL select formatted date from millisecond field

Question

I have a column in a MySQL database that contains a date as milliseconds (epoch). I want to build an SQL query that formats the date as something human readable (day, month, year, hours, minutes, seconds in any format and time zone). Is there an SQL (or MySQL-specific) function to do this?

Solution 1

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'

Solution 2

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                         |
+-------------------------------------------------------+
