The Language of SQL, Second Edition
 
Many SQL texts attempt to serve as an encyclopedic reference on SQL syntax -- an approach that is often counterproductive, because that information is readily available in online references published by the major database vendors. 
 
For SQL beginners, it’s more important for a book to focus on general concepts and to offer clear explanations and examples of what various SQL statements can accomplish. This is that book.
 
A number of features make The Language of SQL unique among introductory SQL books.
 
First, you will not be required to download software or sit with a computer as you read the text. The intent of this book is to provide examples of SQL usage that can be understood simply by reading.
 
Second, topics are organized in an intuitive and logical sequence. SQL keywords are introduced one at a time, allowing you to grow your understanding as you encounter new terms and concepts. 
 
Finally, this book covers the syntax of three widely used databases: Microsoft SQL Server, MySQL, and Oracle. Special “Database Differences” sidebars clearly show you any differences in syntax among these three databases, and instructions are included on how to obtain and install free versions of the databases. 
 
This is the only book you need to gain a quick working knowledge of SQL and relational databases.

商品描述(中文翻譯)

《SQL語言（第二版）》

許多SQL書籍試圖作為SQL語法的百科全書參考資料——這種方法往往適得其反，因為這些資訊在主要資料庫供應商發布的線上參考資料中隨手可得。

對於SQL初學者來說，書籍更重要的是專注於一般概念，並提供清晰的解釋和各種SQL語句能達成的範例。本書正是這樣的書籍。

本書有幾個特點使其在入門SQL書籍中獨樹一幟。

首先，您不需要下載軟體或在閱讀時坐在電腦前。本書的目的是提供可以通過閱讀輕鬆理解的SQL使用範例。

其次，主題以直觀和邏輯的順序組織。SQL關鍵字一次介紹一個，讓您在遇到新術語和概念時逐步增進理解。

最後，本書涵蓋了三種廣泛使用的資料庫的語法：Microsoft SQL Server、MySQL和Oracle。特別的「資料庫差異」側邊欄清楚顯示這三種資料庫之間的語法差異，並包含如何獲取和安裝免費版本資料庫的指示。

這是您獲得SQL和關聯資料庫快速工作知識所需的唯一書籍。

學習如何...
