我想在几天内添加一个日期字符串,并从中减去几个小时和几分钟。也许它没有意义,但这就是我的意思......
INSERT INTO
publication (`city`, `open`, `close`, `show`, `hide`)
VALUES (
'pensacola', -- CITY
NOW(), -- OPEN
DATE_ADD(NOW(), INTERVAL '7 0:0:-1' DAY_SECOND), -- CLOSE
DATE_ADD(NOW(), INTERVAL '10 -3:0:0' DAY_SECOND), -- SHOW
DATE_ADD(NOW(), INTERVAL '17 -3:0:-1' DAY_SECOND) -- HIDE
)
+----+-----------+---------------------+---------------------+---------------------+---------------------+--------+
| id | city | open | close | show | hide | active |
+----+-----------+---------------------+---------------------+---------------------+---------------------+--------+
| 6 | pensacola | 2015-03-09 12:00:00 | 2015-03-16 12:00:01 | 2015-03-19 15:00:00 | 2015-03-26 15:00:01 | 0 |
+----+-----------+---------------------+---------------------+---------------------+---------------------+--------+
这不是我的意图,因为我在我的INTERVAL中指定了一个
+----+-----------+---------------------+---------------------+---------------------+---------------------+--------+
| 6 | pensacola | 2015-03-09 12:00:00 | 2015-03-16 11:59:59 | 2015-03-19 09:00:00 | 2015-03-26 08:59:59 | 0 |
+----+-----------+---------------------+---------------------+---------------------+---------------------+--------+
答案 0 :(得分:2)
添加天数,然后减去时间?
INSERT INTO
publication (`city`, `open`, `close`, `show`, `hide`)
VALUES (
'pensacola', -- CITY
NOW(), -- OPEN
NOW() + INTERVAL 7 DAY - INTERVAL 1 SECOND, --CLOSE
NOW() + INTERVAL 10 DAY - INTERVAL 3 HOUR, -- SHOW
NOW() + INTERVAL 17 DAY - INTERVAL '3:0:1' HOUR_SECOND -- HIDE
)
