Practical Oracle SQL: Mastering the Full Power of Oracle Database
by Kim Berg Hansen (Author)
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 complex statements 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.
