商品描述
If you write programs to run against an Oracle database, you spend a lot
of time and mental energy writing queries to return the data your programs need.
Knowledge of SQL, and particularly of Oracle's implementation of SQL, is the key
to writing good queries in a timely manner. 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:
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. This book
changes that, showing you how to creatively leverage the full power of SQL to
write queries in an Oracle environment
