Also, if you are interested. NULL values in database tables, by the super DB guys like Date and Pascal, are frowned upon. They create "three way logic" which often yields unexpected results and is not part of boolean algebra and is outside of the theory that relational DB is based upon.
They would argue until they passed out that judicious use of default values is a far better way to go. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
