Re: Timestamp with timezone query

Hm?  Works for me:

postgres=# select time with time zone '00:30:00-05' at time zone 'utc';
  timezone
-------------
 05:30:00+00
(1 row)

What are you trying to do with the query?

Thanks, that does it.
select * from table where column = '2006-02-10 19:30:00' AT TIME ZONE
'utc';

I also have a TIME WITH TIMEZONE column that I have to do the same thing
with but AT TIME ZONE can't be used directly. I tried several approaches
but I either get incorrect results or syntax errors. Is there a way to
do the same thing with TIME columns?

Use the AT TIME ZONE construct:

Subject: [GENERAL] Timestamp with timezone query

Hello,

I have a table with TIMESTAMP WITH TIMEZONE column. I would like to
query for a timestamp using a different timezone.

For example if a column contains '2006-02-11 00:30:00-05'
select * from table where column='2006-02-10 19:30:00+00' would return
the column containing '2006-02-11 00:30:00-05'.

From section 8.5.1.3 "To ensure that a literal is treated as timestamp
with time zone, give it the correct explicit type: TIMESTAMP WITH TIME
ZONE '2004-10-19 10:23:54+02'"

So I tried:

select * from table where column = TIMESTAMP WITH TIME ZONE '2006-02-10
19:30:00+00'

But it did not returned the desired result.

I am getting the timestamp as UTC and want to use to build a query, but
I don't want Postgres convert the timestamp. Is there anyway to do this?

Thanks
