Description:
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 regessions
• Row pattern matching to group or distribute rows
• Using MATCH_RECOGNIZE as a row
