I have an app that uses exchangerates for different currencies that get updated once every day at 3pm from the european central bank. The exchangerates are stored in a table that is properly indexed and everything and this all works fine. However, since the exchangerates only change once a day and remain the same all through to the next day, it would have been alot more effective to have some kind of global constants to store these rates. The rates are looked up for every single transaction in the database and I find this to be somewhat of an "overhead"... Is there such a thing as global constants or something close that will do this for me? -- Frettmaestro "Real programmers don't document, if it was hard to write it should be hard to understand"
