I want to update the datetime round to 15 minutes in a MYSQL database table.
If the dateTime is
2013-10-08 10:36:00, I want to convert it into
2013-10-08 10:22:00 to
I have seen this answer but it converts datetime into seconds and return time only, I want date as well.
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
You can get time from the
datetime_field as substring and replace it with the rounded time.
If you want to update the datetime you can reply it and update it with
UPDATE yourtable SET `datetime_field` = REPLACE(datetime_filed,SUBSTRING_INDEX(datetime_field, ' ', -1),SEC_TO_TIME((TIME_TO_SEC(datetime_field) DIV 900) * 900))
