我喜欢

I like the INTERVAL expr unit notation. It feels more readable to me:

SELECT NOW(),
       NOW() + INTERVAL 10 MINUTE;


+--------------------------------+-------------------------------+
|             NOW()              |  NOW() + INTERVAL 10 MINUTE   |
+--------------------------------+-------------------------------+
| August, 12 2013 14:12:56+0000  | August, 12 2013 14:22:56+0000 |
+--------------------------------+-------------------------------+

如果要选择现有行并在结果中添加10分钟:

If you want to select existing rows and add 10 minutes to the result:

SELECT the_date + INTERVAL 10 MINUTE FROM tbl;

如果要更改表中存储的现有行，可以使用:

If you want to alter existing rows stored in a table, you could use:

UPDATE tbl SET the_date = the_date + INTERVAL 10 MINUTE;

如果要在插入时通过 force 值增加10分钟，则需要一个触发器:

If you want increase by force a value by 10 minutes while inserting, you need a trigger:

CREATE TRIGGER ins_future_date BEFORE INSERT ON tbl
FOR EACH ROW
  SET NEW.the_date = NEW.the_date + INTERVAL 10 MINUTE
