Hi Guys
We are migrating to Postgres. In the current system, we use datediff()
function to get the difference between two dates, e.g. datediff
(month, cast('2013-01-01' as timestamp), cast('2013-02-02'
as timestamp) returns 1.
I understand that Postgres h

I need to be able to sort a query by column A, then B or C (which one
is smaller, both are of the same type and table but on different left
joins) and then by D.
How can I do that?
Thanks in advance,

Contrary to my earlier advice assigning a sequential ID (thus using a
numeric TYPE) is one of the exceptions where you can use a number even

Hi,
I have a special need to create a sequence like function.
"O-20110704 -2" which is
"O" for order (there are other types)
"20110704" is for July 4, 2011
'2' the second order of the day for July 4, 2011
I of course can get the type and date. What I do
How about this (that does not require special functions nor triggers:
DROP TABLE IF EXISTS val;
CREATE TABLE val
(
id int,
ts timestamp
);
INSERT INTO val
