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

NOTE the most voted up answer in this chain is INCORRECT! Using HOUR will only return hours as an integer. Below would correct the most popular answer to return hours as an integer and minutes as a decimal (ie 6.5 hours).

TIME_TO_SEC(TIMEDIFF(endDate, startDate))/3600 as hours
