Hello, I have multiplayer card game in Flash/Perl/C and would like to add weekly tournaments/player ratings to it. This means I have to add a table which holds: player id, weekly score (which I update after each round) and the week number. Does anybody has an advice how to save the week number? If I save it as a timestamp then calculating realtime statistics (on a player profile click) will probably be CPU-intensive, because I have to calculate the week numbers each time. If I save it as string "2010/52" then it's difficult to show statistics for a period of time (like for the last 12 months) if there is a new year inbetween. Maybe there is a better way? I'm using postgresql-server-8.3.6 and OpenBSD 4.5 Regards Alex -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
