[SQL] What day is it - when it isn't NOW()?

[tomg]

Hi,

SELECT to_char(now(), 'Day');  returns Friday as I'd hoped.
But how do I return the day of the week for a specific date other
than now()?  I'm looking for something along the lines of:
SELECT to_char('2003-08-04', 'Day') without much success.

Can anyone point me to the right function/combination of functions
to achieve this?

Thanks!

Hey Josh, how goes...yeah I bumbled around date/time functions for awhile but
couldn't find the right syntax...maybe I need new glasses? ;-)

I tried this but I don't need an integer returned so I went with the
to_char() approach.  Thanks for tip - and thanks to Rod as well.

This is what I went for as it is the closest to the MySQL/Oracle syntax
I use for the same purpose, particularly Oracle:

$query = qq |SELECT DATE_FORMAT('$start_date', '%W')| if ($dbtype eq 'mysql');
$query = qq |SELECT TO_CHAR('start_date'::date, 'Day') if ($dbtype eq 'postgres');
$query = qq |SELECT TO_CHAR(TO_DATE('$start_date'), 'Day') FROM DUAL| if ($dbtype eq 
'oracle');

Thanks again fellas - have a nice weekend!

Cheers

[SQL] pg_dump backwards compat issues

[tomg]

Hi all, anybody have a sed script (or flags for pg_dump) that
will make a pg_dump 7.4 dump load into a Pg 7.3.x backend?

TIA!
