Re: Date addition/subtraction

[Franco Bruno Borghesi <fborghesi@xxxxxxxxx>]

It's easy. You have to know that INTERVAL data type exist, so:

SELECT current_date - '30 days'::interval
SELECT current_timestamp - '1 hour'::interval

Hi

How in postgres can I do date/time subtraction or addition.
e.g. If I want to get today's date - 30 days? or current_timestamp - 1 hour?

Thanks
Craig
