Subject: Re: [SQL] subtract a day from the NOW function
I just figured it out. The solution is:
select to_char((now() - interval '1 day'), 'YYYYMMDD');
Thanks,

Table
Field "some_timestamp" is a timestamp.
In a "WHERE" statement I need to compare a timestamp field in a table
"some_timestamp" to now() - one day.
Example:
SELECT some_timestamp WHERE to_char(some_timestamp, 'YYYYMMDD') >
(to_char(now(), 'YYYYMMDD') - 1 day);
The statement "to_char(now(), 'YYYYMMDD') - 1 day)" is obviously
incorrect. I just need to know how to form this in a way that will
work.
If there is an entirely different solution I am all for it. Do note
that I started down this path because I want to exclude the hour,
minutes and seconds found in the field "some_timestamp" and in the
function now().
