PostgreSQL, checking date relative to "today"

Was wondering if someone could assist with some Postgres. I have a table which has a column called mydate which is a postgres date type. I want to do something like:

SELECT * FROM MyTable WHERE mydate > [Today-1year]

I've never used Postgres before and I'm sure I just need to know the name of some functions- I'll gladly look up the reference myself. Can anyone point me in the right direction?

Thanks!

Solution 1:

select * from mytable where mydate > now() - interval '1 year';

If you only care about the date and not the time, substitute current_date for now()

select * from mytable where mydate > current_date - interval '1 year';

Solution 2:

I think this will do it:

SELECT * FROM MyTable WHERE mydate > now()::date - 365;

Solution 3:

This should give you the current date minus 1 year:

select now() - interval '1 year';
