finding Datetime difference in seconds

[prileep]

Hi,
I want to find the the exact difference between two dates in seconds through MySQL query.
Version: 4.1
Platform: Linux
Source code:
>select datediff('2007-01-09 10:24:46','2007-01-09 10:23:46')
The datediff() function has only two datetime parameters and returns the difference in days.Instead if i want the value to be returned in seconds,what is the possible way??

Use the TIMEDIFF and TIME_TO_SEC functions, as in:

SELECT TIME_TO_SEC(TIMEDIFF('2007-01-09 10:24:46','2007-01-09 10:23:46'));

I am really thankful to u with the solution u given for this. I could achieve this by some other twisted method. But your solution helped me to calculate in subqueries itself,because iwanted to calculate in subquery.

SELECT TIME_TO_SEC(TIMEDIFF('2007-01-09 10:24:46','2007-01-09 10:23:46'));

Note that the solution only works when the datetimes are less than 35 days apart!
TIMEDIFF retuns a TIME datatype, and the max value for TIME is 838:59:59 hours (=34,96 days)
