Title: A Useless Reference
Review: This books does not make sense. It attempts to provide a reference to various "dialects" of SQL, but it does a poor job on all of them. I (like most developers) only use a single vendor's SQL (Oracle in my case), so I can't comment too much on the accuracy of the others, but there are so many errors and ommissions in the Oracle SQL that the book is less than useless. As an alternative, if you use Oracle I strongly recommend Oracle SQL: The Essential Reference (also from O'Reilly) by Kreines - it is exactly what it claims to be and is what this book should have been! If you don't use Oracle - I guess there are still of few of you out there :) - there must be something better.
Is the review positive or negative?
