I haven't heard any replies from this, so in the meantime I've found a
hacky way to get the output I desire. I'm basically calculating the
hours on the fly and piecing together a formatted string with
concatenations like this:
SELECT
(((EXTRACT(day from time_idle)*24)+EXTRACT(hour from time_idle)) || ':' ||
EXTRACT(minute from time_idle) || ':' || EXTRACT(second from
time_idle))::interval AS myinterval
FROM
( SELECT ('2006-09-15T23:59:00'::timestamp - '2006-09-01
09:30:41'::timestamp) AS time_idle) FROM_TABLE;
If anyone knows a better/proper way to get this result, let me know.
Thanks,
Graham.

Hi,
I'm trying to format the output of a time interval so that it displays
as HH:MM:SS no matter how many days it spans. So for instance, an
interval of 2 days 4 hours and 0 minutes would look something like
"52:00:00". The documentation for to_char states that:
"|to_char(interval)| formats HH and HH12 as hours in a single day,
while HH24 can output hours exceeding a single day, e.g. >24."
However I can not get it to work with time intervals that span more
than 1 day. For instance, the following query returns this time
interval:
Query:
select ('2006-09-15T23:59:00'::timestamp - '2006-09-01
09:30:41'::timestamp);
Result:
14 days 14:28:19
But when I run to_char on this with HH24, it doesn't take into effect
the number of days:
Query:
select to_char(('2006-09-15T23:59:00'::timestamp - '2006-09-01
09:30:41'::timestamp), 'HH24:MI:SS');
Result:
14:28:19
It just gives me the offset of hours, min, seconds on that 14th day.
The result I'm looking for is: 350:28:19
What am I doing wrong, or how can I get this desired output? Thanks,
