问题描述
我想将MYSQL数据库表中的日期时间更新为15分钟.
I want to update the datetime round to 15 minutes in a MYSQL database table.
例如:
如果dateTime为2013-10-08 10:36:00，我想将其转换为2013-10-08 10:30:00同样，2013-10-08 10:22:00至2013-10-08 10:15:00
If the dateTime is 2013-10-08 10:36:00, I want to convert it into 2013-10-08 10:30:00Similarly,2013-10-08 10:22:00 to 2013-10-08 10:15:00
我已经看到此答案但是它将datetime转换为秒并仅返回时间，我也希望获得日期.
I have seen this answer but it converts datetime into seconds and return time only, I want date as well.
谢谢
推荐答案
您看到的答案非常有用，请尝试
The answer you have seen is quite useful, try this
SELECT SUBSTRING_INDEX(datetime_field, ' ', -1) AS old_time,SEC_TO_TIME((TIME_TO_SEC(datetime_field) DIV 900) * 900) AS rounded_time, datetime_field FROM yourtable
您可以从datetime_field中获取时间作为子字符串，并将其替换为四舍五入的时间.
You can get time from the datetime_field as substring and replace it with the rounded time.
如果您想更新日期时间，可以回复并使用update功能对其进行更新:
If you want to update the datetime you can reply it and update it with update function:
UPDATE yourtable SET `datetime_field` = REPLACE(datetime_filed,SUBSTRING_INDEX(datetime_field, ' ', -1),SEC_TO_TIME((TIME_TO_SEC(datetime_field) DIV 900) * 900))
