MySQL Programming Interview Question:

How To Calculate the Difference between Two Time Values?

Submitted by: Administrator

If you have two time values, and you want to know the time difference between them, you can use the TIMEDIFF(time1, time2) function as shown below:

SELECT TIMEDIFF(TIME('19:26:50'), TIME('09:26:50'))
FROM DUAL;
10:00:00

SELECT TIMEDIFF('1997-03-01 19:26:50.000123',
'1997-02-28 09:26:50.000000') FROM DUAL;
34:00:00.000123
