Answer 1

你可以看一下FROM_UNIXTIME()

mysql> SELECT FROM_UNIXTIME(1196440219); 
    -> '2007-11-30 10:30:19' 
mysql> SELECT FROM_UNIXTIME(1196440219) + 0; 
    -> 20071130103019.000000 
mysql> SELECT FROM_UNIXTIME(UNIX_TIMESTAMP(), '%Y %D %M %h:%i:%s %x'); 
    -> '2007 30th November 10:30:59 2007' 

要查看可以使用的符，有一个在this location.

Answer 3

SELECT FROM_UNIXTIME(your_column, '%Y-%m-%d') as formatted_time FROM your_table; 

返回your_column格式化为'2017-08-10';
