Especially well done are the short solutions. These make for a good foundation for developing quite complicated SQL code.

I can see why a downloadable 'package' would be nice. However, since the solutions are short and the text that accompanies the solution is very to the point, I found it not particularly necessary for a downloadable set of source. Ah, but it would be nice...

The coverage of the many many aspects SQL is quite amazing. The explanation of the 'window' functions is clear. I especially like the use of 'advanced' features early in the book and then seeing the explanations.
The book does really help generate ideas--As I am sure the author intended.

I will confess that I have two copies -- one a work and one at home. Overkill? I did not think so when I could grab the book for an solution/idea just about anywhere I happened to be.
