How to determine the time 'amount' between two times?


I have a table which contains time management data. We have:

R = Registration
A = Arrival
D = Departure

Time information for A and D can be in the table multiple times for one of our employees. What I would like to do is show the amount of time between the R and the last D of the day.

So R = 08:00 and the last D = 18:30 so the time amount would be 10 hours and 30 minutes.

Is there any way to do this in MySQL?

You may use the timediff() function:

SELECT MAX(TIMEDIFF(D, R)) FROM thetable WHERE condition
