mysql timediff to hours

Question

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,startDa

Answer 1

you can use mysql funcion timestampdiff like below

TIMESTAMPDIFF(HOUR, '2018-06-01 00:00:00', '2018-06-01 12:00:00') 

Answer 2

for getting Diffrence in Hour :

Hour(TIMEDIFF(date1,date2)) as Hour1

for getting Diffrence in Minute :

Minute(TIMEDIFF(date1,date2)) as Minute1

for getting Diffrence in Second :

Second(TIMEDIFF(date1,date2)) as Second1

Answer 3

HOUR(TIMEDIFF(endDate, startDate))

might work—if I'm reading the docs correctly.

Answer 4

select hour(timediff('2017-01-01 00:00:00', '2017-01-01 00:01:00'));
 return 1

select hour(timediff('2017-01-01 00:01:00', '2017-01-01 00:00:00'));
 return 1 

select time_to_sec(timediff('2017-01-01 00:00:00', '2017-01-01 00:00:05'));
return -5

select time_to_sec(timediff('2017-01-01 00:00:00', '2017-01-01 00:00:05'))/60 as 'minutes' ;
return -0.0833  

if you have the seconds you can convert it as you want or what and hours(..) will not use it when i compare because it's always postive value
