Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Didn't appeal to me - I wish I hadn't bought it!

I can't understand why this book has been so highly rated. I bought it on the basis of the other reviews. I have found it lacking in all the areas I have needed to look up. I have found one or two useful things as well; but it seems to lack some basic (and I don't mean beginner) coverage. For example INSERTs are covered; yet there isn't any coverage about how to return an id from the INSERT. I believe the book could be improved just by addressing some of the questions being asked on SQL/VB sites. I also did not like the layout of the book. I have used SQL since the early days (1983).
