Query: Nice in concept ....

I had to purchase this book for a class at Lansing Community College, and have had nothing but problems. The examples are unclear and overly wordy. The number of typo's and other errors in this book are unforgivable, and it appears to have been rushed to publication.It would have been a nice addition to see some kind of hints given for the end of chapter exercises, and the number of records you would find in a properly created query, especially since later exercises build off a query from Chap 2.If you have to use this book for a class, you may want to buy another book as an additional reference.
