[GENERAL] Date addition/subtraction
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?

Re: [GENERAL] Date addition/subtraction

You have to know that INTERVAL data type exist, so: SELECT current_date - '30 days'::interval SELECT current_timestamp - '1 hour'::interval 2005/5/3, Craig Bryden [EMAIL PROTECTED]: HiHow 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?ThanksCraig---(end of broadcast)--- TIP 3: if posting/reading through Usenet, please send an appropriatesubscribe-nomail command to [EMAIL PROTECTED] so that yourmessage can get through to the mailing list cleanly
