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?

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!

I think this will work for you.

Have a nice day
