Query: A severe disappointment

I really expected much more than this from O'Reilly. Almost half of the book is just cut-and-pasted in from the Oracle online documentation (which is available free online!)! Oracle should be getting half the royalties, or the book should cost 50% less. Plus, it doesn't cover 8i so its coverage of Oracle8 topics is incomplete and incorrect. I can't believe this is the best these authors and O'Reilly can do. I rate it 0 stars and plan to send my copy to O'Reilly with comments.
