You can just save it as timestamp and try the following query. select * from table where date < (now() - interval '1 hour'); Regards Chandra Sekhar Surapaneni -----Original Message----- From: pgsql-general-owner@xxxxxxxxxxxxxx [mailto:pgsql-general-owner@xxxxxxxxxxxxxx] On Behalf Of Brandon Metcalf Sent: Thursday, February 23, 2006 1:56 PM To: pgsql-general@xxxxxxxxxxxxxx Subject: [GENERAL] subtracting minutes from date What is the best way to store a timestamp if all I need to do is select rows where this timestamp is less than 60 minutes prior to the current time? If I have a column called date with data type timestamp without time zone I know I can use SELECT * FROM table WHERE date < (now()::DATE - 7)::TIMESTAMP; to select rows where date is older than seven days. I'm not quite sure how to interpret now()::DATE::TIMESTAMP since I'm not able to answer my own question. I've tried things like: SELECT * FROM table WHERE date < now()::DATE::(TIMESTAMP - 60); but this gives a syntax error.
