I'm new to SQL, but not new to databases. The author does a decent job of starting out in Chapter 1 with a discussion explaining databases. At the end of the chapter, he strongly encourages the reader to "create the sample database and run the examples in the book."

The database model is extensive, and it would take considerable time to replicate the database. This is time that I am not learning about SQL, which is why I started the book in the first place. He gives a link to the publishers website to download the SQL code to do his exercises, but the database is not there.

Readers expect that learning SQL requires a a sample database, and that database should be included with the book. That the database is not provided, and is not downloadable, is unacceptable.

There are MANY other choices where the databases are included with the book. I have abandoned "SQL Demystified" and will start over with another book that doesn't expect the database to be re-created.

我是SQL的新手，但对数据库并不陌生。作者在第1章中做得很好，一开始就对数据库进行了讨论解释。在这一章的末尾，他强烈鼓励读者 "创建样本数据库并运行书中的例子"。

数据库模型很广泛，要复制数据库需要相当多的时间。这是我没有学习SQL的时间，而这正是我开始阅读这本书的初衷。他给出了一个出版商网站的链接，可以下载SQL代码来做他的练习，但数据库并不在那里。

读者期望学习SQL需要一个样本数据库，而这个数据库应该包括在书中。没有提供数据库，也不能下载，这是不可接受的。

有很多其他的选择，数据库都是随书提供的。我已经放弃了 "SQL解密"，并将从另一本不期望重新创建数据库的书开始
