Yes, regarding these 3, how can they be considered absolute do's or don'ts? I didn't take Cary's material to mean ignore physical IO's but rather to show the importance and impact of logical IO's. Too many PIOs could still be an issue. (I would say maybe Cary could speak to this, but I'd rather him spend that time on his book, which I'll be ordering as soon as it's available.) The others have their places as well. I wouldn't practice or preach that bind variables are always, always the right way (usually, but not always). Why not ASSM? Surely, there could be circumstances where ASSM is a good way, or at least ok. Do Use Bind Variables Do tune to Reduce Logical IO's Not Physical IO's. Don't Use ASSM
Please consider, Robert, that I'm not challenging your list as these may be very good rules to live by. I don't usually take any 'rule' as hard and fast until I can test it, but there may be others reading the list that would benefit greatly to understand why these things should or should not be done. Thanks for your input, it helps us all learn.
