SQL Pocket Guide
The complexity of developing database queries with SQL is a challenge often requiring frequent documentation searches. The best feature of this guide is its breadth of detail offered. It provides a high-level view of database structures and provides useful details for taking strategies available in one implementation and possibly using it in another database engine. An example of thi. An example of this are the references from custom database function naming of Oracle's "analytic functions" and DB2's "OLAP functions" to the standard's name of "windowing functions". This allows you to take the naming you are familiar with, have been taught, or overheard and refer to it using that name and finding an appropriate redirection.

Post a Comment. Surely this book was quite an undertaking for the author. The book provides a good amount of platform-specific detail when necessary. This is good detail that shows the author clearly has experience and insight which provide value to the reader. Regularly, the author breaks a topic down by platform, which is helpful in navigation. While the book provides syntax and examples on standard ANSI SQL statements in each platform, it avoids comparing and contrasting usage except when necessary. This is a good thing, I can't see why the author need to include full cross references of simple syntax.
