Subject: [GENERAL] extracting time from a timestamp with time zone field
I have the following view
CREATE OR REPLACE VIEW VoIP AS
SELECT RadAcctId AS ID, NASIPAddress AS GWIP, AcctSessionTime AS
Call_Seconds, EXTRACT(YEAR FROM (h323setuptime AT TIME ZONE 'UTC')) AS
Year, EXTRACT(MONTH FROM (h323setuptime AT TIME ZONE 'UTC')) AS Month,
EXTRACT(DAY FROM (h323setuptime AT TIME ZONE 'UTC')) AS Day,
h323ConnectTime AT TIME ZONE 'UTC' AS Time, CalledStationId AS Number,
H323RemoteAddress AS Remote_IP, h323ConfID AS CondID
FROM StopVoIP;
but I wish the "Time" column to display time only, not date and time. I have
read everything I can find in the postgres docs regarding formatiing and
extracting info from timestamp fields, and I cannot figure out how to do
this. Sure someone else has done this before!!
h323setuptime is: h323SetupTime timestamp with time zone NOT NULL
Can someone help?
(I would recomend that if postgres has some easy way of doing this, that the
info be added to
http://www.postgresql.org/docs/view.php?version=7.3&idoc=1&file=functions-da
tetime.html
for others to find)
Thanks in advance.
