While I appreciate the style and find it pretty useful, I am a bit disappointed for the choice of title (hence the 4 stars).
"Refactoring" is usually succinctly described as "improving quality without changing the behaviour of a given piece of code" - and in this sense the title is more or less adequate. The problem is that the only concept of "quality" in this case regards query efficiency.
I suppose this is more or less what a DBA or SQL expert really cares about, but if you expected patterns (and anti-patterns), the concept of code smells or - maybe more appropriately - how to incrementally redesign your tables to make them "better"... well, this book is not for you.
In fact you are probably looking for "Agile Database Techniques" or some other title. This one is 99% about query rewriting and maybe 1% of other techniques like change indexes or even restructure tables. But always and only in order to improve throughput.
If this is the type of "quality" you are concerned about, I doubt you can find something better. For a more balanced concept of "Refactoring" you should probably check some other book. (
