Question

I’m giving input to TIMESTAMPDIFF(HOUR,'29-10-2012','19-11-2012') but I’m getting output as 504 but the value should be 510.

The output is 510 because start value is 29/10/2012 05:13.

Is there alternative to this function which gives Day,Hour,Minute,Second difference between two dates?

Answer 1

You pass DATE values in TIMESTAMPDIFF function, all is correct –

• 3 days in october: 2012-10-29, 2012-10-30, 2012-10-31 = 3 * 24 = 72
• 18 days in november: 2012-11-01…2012-11-18 = 18 * 24 = 432

72 + 432 = 504

If you want to count hours, minutes or seconds, then you should pass two DATETIME values –

SELECT TIMESTAMPDIFF(HOUR,'2012-10-29 05:13:00','2012-11-19 00:00:00') hours;
