In this book, the authors share their knowledge of Oracle SQL, and show you many creative techniques that you can use to advantage in your own applications.This book shows you how to:
- Leverage Oracle's vast library of built-in SQL functions
- Query time-based data, and write joins involving date and time ranges
- Use Oracle SQL's hierarchical query features to deal with data best represented in a tree format
- Use DECODE and CASE to implement conditional logic in your queries
- Use Oracle's new, analytic SQL features to write ranking queries, lag and lead queries, windowing queries, and more
- Join data from two or more tables using the newly supported SQL92 join syntax
In addition, you'll see how SQL can best be integrated with PL/SQL. You'll also learn various best practices to help you write SQL queries that perform efficiently.Precious few books on the market today go beyond discussing syntax and the barest rudiments of using Oracle SQL.

Paid for itself in 10 minutes
By M. McLeod
A clear explaination of how to use multiple nested views has saved the day. I can now run a single query on my large table (the table has 83 Million rows in it) and it completes by in a few hours. I have enjoyed reading it and becoming more experienced in SQL. In the past I would use Perl/DBI to access the database but now I do it through sqlplus because of the large datasets I am working with. I wish I bought this book a loong time ago.

What can you do with Oracle SQL?
By Tracy Kingsley
Half of this 450 page book surveys basic SQL, and the other half is on features Oracle added to SQL in versions 9i and especially 10g. I bought the book because I believed the title, and the reviews here that said it was an excellent reference. But, to quote one of its authors, "This book is NOT a reference manual, and it is NOT an administrator's guide". It's an overview of SQL only. It is not an introduction; nor can it be used, reference book-fashion, all by itself.
So for my purposes, I was quite disappointed. But the book has some utility, in its explanations of what can be done with Oracle SQL. Especially in the explanations of analytic functions, regular expressions, and XML. It's like a series of magazine articles, with discussion and examples.
The book has some weaknesses:
* The index is very skimpy and incomplete. This is what you'd expect actually, in a book that isn't ever meant to be referred back to.
* The focus on SQL is diluted and inconsistent. For example, there is an explanation on how to set up partitioning. Another section compares Oracle's implementation of regular expressions to Perl's . Sometimes background and comparisons are present, sometimes they're not.
* There isn't much explanation of *why* you'd want to do some of the *whats* that can be done. Yes, it's possible to build classes and objects into a database, but why do it in SQL instead of Java? (Of course the *hows* would be quite inadequate, if this were a how-to book).
* There is too much explanation of how things used to be done in 8i. That version was five years old back when this edition was published. 8i shouldn't take up more than a paragraph or three in a book that purports to cover 9i and 10g.
In summary, if you don't read trade magazines, and you don't care to spend your time on Oracle websites and forums, and you know you won't have access to 11g anytime soon, you may find this book a decent (altho somewhat pricey) way to broaden your horizons of what you can do with Oracle SQL.
