Title: RE: How Reliable is Explain Plan in 9.2

Thanks Wolfgang ... I understand your point ...

I was just trying to be a little cynical ... about these *facts* ... the very elements about which Oracle tells us to rely upon.

1. Who in their right mind would add/drop an index on a live production database without thinking 'A Ha ... dropping this unique key index shouldn't hurt my 10 gazillion row table at all.'?

2. I am now worried about optimizer taking past executions into account ... if you have a person consistently committing mistakes, and you expect this person to learn from his/her experience, what do you think will happen ??

(Stay with me ... it's been a bad morning so far ... a wrong DB was refreshed and someone decided last night to arrange a demo this afternoon.)
