Hi all,
Could anyone please tell an easy way to get total hours or minutes from an
interval ?
SELECT SUM(stop_date_time - start_date_time) AS tot_time FROM work_times WHERE
user_id = 1;
tot_time
-----------------
2 days 14:08:44
I'd like to have this like ... AS tot_hours ...
tot_hours
-----------------
62
and ... AS tot_minutes ...
tot_minutes
-----------------
3728
Maybe even ... AS tot_hours_minutes_seconds
tot_hours_minutes_seconds
-----------------
62:08:44
start_date_time and stop_date_time are stored as timestamp without time zone,
using Pg 8.1.5 on CentOs 4.4
???
Thanks,
