Interval (days) in PostgreSQL with two parameters

Question

In this query:

Select * from table where future_date - CURRENT_DATE <= '10';

It returns the interval of 10 days or less.

How to add two parameters? Example:

Select * from table where future_date - CURRENT_DATE <= '10' AND >= '30';

I already tried:

Select * from table where future_date - CURRENT_DATE BETWEEN '10' AND '30'

But it doesn't work.

Answer 1

SELECT  *
FROM    mytable
WHERE   future_date BETWEEN CURRENT_DATE + '10 days'::INTERVAL AND CURRENT_DATE + '30 days'::INTERVAL
