Обсуждение: Date Formatting
I am writing timestamps to file and the formatting is currently 2002-06-06 00:00:00.0. Is there a function to only write the date and also to format it something like MM/dd/yyyy ? Thanks Tom

This may give you what you need:
date("M d Y H:i:s",$timestamp)
On another note, is there a builtin command to change
time display from 19:00 to 7:00 pm?

Hi Tom -
select cast (now() as date) as date;
date
------------
2002-05-03
Depending on your application (e.g. perl/php script), that output is easy
enough change it around to what you want or you could certainly write a
function to do it -- something I have yet to do! I think such a function
would be fairly easy to do since you're just rearranging the
output, but doesn't everything look easy at the outset? You didn't
mention the context of what you need this for, so there are lots of ways
to do this.

You might need to manipulate the output using sed/awk/Perl to get exactly what you want To get back to the default use 'ISO' or 'European' depending on where you started from. HTH Richard A Lough
Is there a builtin function in Postgres to display the time as XX:XX am or XX:XX pm? Cheers, Tom Hodges

I have 3 queries and some php to run them. What I need is
to display the time in a HH:MM am format. Doesn't need to
be stored that way in the table?
These two add or update records:
insert into feasts (timestamp, date, time, address, direction,
host, phone)
values ('current_timestamp', '$date', '$time','$addr',
'$directions','$host','$phone');
update feasts set date='$date', time='$time', host='$host',
phone='$phon', address=$addr','direction='$directions'
where feast_id='$feast_id';
These retrieve and display records:
select * from feasts;
$time = $result->fields[3];
and in a form,
print ("<INPUT TYPE= \"text\" NAME=\"time\" VALUE= \"$time\"><BR>\n");
and
print ("<INPUT TYPE= \"text\" NAME=\"time\">\n");
So I am not sure how to do this.
Thanks,
Tom

Right, so instead of: SELECT timestamp_field FROM mytable; you want: SELECT to_char( timestamp_field, 'HH12:MI am') FROM mytable; And for lots more information, look at the docs: > > On 9 May 2002 at 20:55, Larry Rosenman wrote: > > > look at the to_char function on > > http://www.lerctr.org/postgresql/functions-formatting.html > > Regards, Andrew. -- -------------------------------------------------------------------- Andrew @ Catalyst .Net.NZ Ltd, PO Box 11-053, Manners St, Wellington WEB: http://catalyst.net.nz/ PHYS: Level 2, 150-154 Willis St DDI: +64(4)916-7201 MOB: +64(21)635-694 OFFICE: +64(4)499-2267 Are you enrolled at http://schoolreunions.co.nz/ yet?
SELECT to_char( timestamp, 'HH12:MI am') FROM feasts; or time from psql prompt gives Function 'to_char(time, unknown)' does not exist Unable to identify a function that satisfies the given argument types you may need to add explicit typecasts time has the type of time Any idea?

SELECT to_char( mytimefield::timestamp, 'HH12:MI am') FROM feasts;
And I can't recommend strongly enough that you read the manual, which is
quite clear on this sort of thing.

Problem solved.
I read the manual. The to_char function doesn't work
with type time. When I cast it to type timestamp the
database library I am using (php_lib_login and ADODB)
objects.
So I solved it with the php date and strtotime functions.
$time = $result->fields[3];
$time2 = (date("h:i a",strtotime($time)));
This allows flexible time display. My update and add
buttons both store correct data in the table.
Thanks for all the helpful suggestions,
Tom
