| | | | Yes, indeed, John is (as evah) right. Let me weigh in here as well... Putting meaning in keys is a sign of not very well seasoned designers, IMHO. A pretty strong principle of database design is NOT to let your key have business meaning. Get keys (...) (25 years ago, 25-Aug-99, to lugnet.db.brictionary)
