Query: Simply awful

I just picked up this book yesterday and have already found numerous errors in the code samples.I was expecting advanced material but most of this is pretty elementary introductory stuff.On top of that, some of their designs are just plain stupid. For example, their "technique" of paging through large record sets using ranges of the primary key ID is just wrong wrong wrong. The technique won't work unless your entire record set consists of perfectly continuous IDs! It's absolutely incredible that they would foist such (...) upon us.Stay away from this one.
