You could use unix_timestamp
for dates after 1970
:
您可以在unix_timestamp
以下日期之后使用1970
:
SELECT (unix_timestamp('2013-01-01 10:10:10')
- unix_timestamp('1970-01-01 00:00:00'))/60
- Convert both dates to seconds from
1970-01-01
- Substract them
- Divide by 60 to get minutes
- 将两个日期转换为秒
1970-01-01
- 减去它们
- 除以 60 得到分钟
EDIT:
编辑:
Adding Minutes: change date to unixtime -> add var * 60sec -> convert back to date
添加分钟: change date to unixtime -> add var * 60sec -> convert back to date
SELECT from_unixtime(unix_timestamp('2013-01-01 10:10:10') + 10 * 60) AS result
