Yes, I agree perfectly... I never thought of that! I would really like it if some more info was added to the docs
regardinginfo on rules and triggers. The section on update rules is quite good, but some more would never hurt. One
pointin the trigger vs rules section which at least to me is very important is the simple fact that you cannot have a
triggeron a select... Ok I understand why - but it took some time...
Thank you for answering my questions!
regards,
Aasmund.
