Quite disappointed. It is unfortunate that mySQL/mSQL is probably the best printed material on this subject. As a newcomer to mySQL, but with solid backgrounding in dbase and other database software, I expected little difficulty in picking this up. Based on my experience with other OReilly publications, this book offered the promise of being a useful learning tool. However, after running into multiple indecipherable typographical errors, and example programs that didn't work, I've given up on using this as anything but a highly questionable reference.
