Greetings,
I've got an interesting problem. I have a table with a column full of
timestamps. I need a means of returning only the rows which have a
timestamp that falls after the last 16:00 and before the next 16:00
(on the clock), regardless of date.
For example, let's say I've got this in my table:
date_created
----------------------
10-05-2007 00:44:45
10-04-2007 17:59:43
10-04-2007 19:12:00
10-04-2007 17:59:54
10-03-2007 21:00:56
10-04-2007 19:12:00
10-03-2007 21:00:58
and let's say that the current timestamp (select now()) returns:
2007-10-05 15:18:54.133368-07
I need to get back just the following rows:
10-05-2007 00:44:45
10-04-2007 17:59:43
10-04-2007 19:12:00
10-04-2007 17:59:54
10-04-2007 19:12:00
The closest I've come is the following, which unfortunately only works
if its not yet after 16:00 on the current date:
select count(id) from footable0 where ('today'::timestamp - interval
'8 hours') < date_created::timestamp AND ('tomorrow'::timestamp +
interval '8 hours') > date_created::timestamp ;
thanks for all help, suggestions & input.
