Problem with showing time diff?
I have the following select:
select to_char((Log_Fortrykk.SistePlate::time -
OrdreNew.SistePlate::time)::interval,'HH24:MI') as diff from Log_Fortrykk
I need the output to be HH:MM, e.g. 00:09... But my prb is when this diff is less than 0,
it shows as 00:-9 and not -00:09
How can I fix this?
Regards,
BTJ

The documentation deprecates to_char(interval, text) and the Release
Notes for 8.0 say that 8.1 will remove it.
You might be able to use substring():
SELECT substring('-00:09:10'::interval from '(.*):[0-9][0-9]$');
substring
-----------
-00:09
