Обсуждение: compare month

Hi all of you PostGreSQL fans,

I need to run a query like

SELECT users from userlog where lastlogindate is less than one month
or
SELECT users from userlog where lastlogindate is less than 15 days

Can any one help with sql example?

Hey, read my answer in #postgresql ;-)

08:48 < shakil> i neeed to compare days in sql query like "SELECT users from userlog where lastLoginDate is 7 days old"
08:48 < shakil> can any one help?
08:49 < shakil> or SELECT users from userlog where lastLoginDate is one month old
08:51 < akretschmer> shakil: select .... where lastLoginDate > current_date - '7days'::interval

True fans spell it PostgreSQL :)

select users
from userlog
where lastlogindate > current_timestamp - 1 * interval '1 month';

select users
from userlog
where lastlogindate > current_timestamp - 15 * interval '1 day';

You can also use current_date instead of current_timestamp, depending
on your desired data type.

Hope this helps!

Hi,
SELECT users from userlog where lastlogindate > CURRENT_DATE-'1
month'::interval;
or
SELECT users from userlog where lastlogindate > CURRENT_DATE-'15
days'::interval;


I think this will work for you.

Have a nice day
