mysql timediff to hours
mysql, php
Solution
`TIMEDIFF(endDate, startDate)` outputs in DateTime format, so flat that to timestamp and devide by (60*60)
SELECT (UNIX_TIMESTAMP(TIMEDIFF(endDate, startDate))/(60*60)) AS hours_difference
FROM tasks
Edit: Alternatively,TimestampDiff may also provide a valid solution in more elegant way providing its example:
SELECT TIMESTAMPDIFF(MONTH,'2003-02-01','2003-05-01');
And your solution can be:
SELECT TIMESTAMPDIFF(HOUR, startDate, endDate) AS hours_different
FROM tasks
Problem
I'm Trying to get the timediff from my table and convert it to hours (it's for an hourly billed service) SELECT TIME_TO_SEC(TIMEDIFF(endDate,startDate))/3600 FROM tasks > where endDate and startDate are in datetime format is there another way (more efficient) to do this task? Thanks !
