Practical Oracle SQL

Write powerful queries using as much of the feature-rich Oracle SQL language as possible, progressing beyond the simple queries of basic SQL as standardized in SQL-92. Both standard SQL and Oracle’s own extensions to the language have progressed far over the decades in terms of how much you can work with your data in a single, albeit sometimes complex, SQL statement. If you already know the basics of SQL, this book provides many examples of how to write even more advanced SQL to huge benefit in your applications, such as: Pivoting rows to columns and columns to rows Recursion in SQL with MODEL and WITH clauses Answering Top-N questions Forecasting with linear regressions Row pattern matching to group or distribute rows Using MATCH_RECOGNIZE as a row processing engine The process of starting from simpler statements in SQL, and gradually working those statements stepwise into more complexstatements that deliver powerful results, is covered in each example. By trying out the recipes and examples for yourself, you will put together the building blocks into powerful SQL statements that will make your application run circles around your competitors. What You Will Learn Take full advantage of advanced and modern features in Oracle SQL Recognize when modern SQL constructs can help create better applications Improve SQL query building skills through stepwise refinement Apply set-based thinking to process more data in fewer queries Make cross-row calculations with analytic functions Search for patterns across multiple rows using row pattern matching Break complex calculations into smaller steps with subquery factoring Who This Book Is For Oracle Database developers who already knowsome SQL, but rarely use features of the language beyond the SQL-92 standard. And it is for developers who would like to apply the more modern features of Oracle SQL, but don’t know where to start. The book also is for those who want to write increasingly complex queries in a stepwise and understandable manner. Experienced developers will use the book to develop more efficient queries using the advanced features of the Oracle SQL language.

Mastering Oracle PL/SQL

Do you need more from a PL/SQL book than just the correct keywords and some pretty syntax diagrams? Have you been searching in vain for real-world examples and genuine strategies for maximizing the benefits of PL/SQL within your organization? You'll find them here in Mastering Oracle PL/SQL: Practical Solutions, the inaugural title of the pioneering OakTable Press series from Apress. This isn't a tutorial on how to code PL/SQL. It's designed to show you how to code PL/SQL well. It shows you how to write code that will run quickly and wont break in high-load, multiuser environments. It covers the vast array of the functionality that PL/SQL provides, including effective handling of relational and abstract data, security, triggers, dynamic web content presentation from within the database, creation of a DBA toolkit, and effective debugging techniques. This book sets out to redress the unjust criticism leveled at PL/SQL in years gone by. It gives you the tools and techniques to ensure that, whatever your needs are, the PL/SQL you build will run as efficiently as possible. The practical solutions provided in this book will help you to realize the true power and functionality PL/SQL can offer your projects. If you're brand-new to PL/SQL, then you'll want to take some time to get familiar with the language before tackling this book. It's not for the total beginner. But once youre up and running, you'll find this book an invaluable guide for ensuring that the PL/SQL solutions you build are robust, perform well, and are easy to maintain.
