Karen Morton and her team help you master powerful aspects of Oracle SQL not found in competing databases. Youll learn analytic functions, the MODEL clause, and advanced grouping syntaxfeatures thatÂ will helpÂ in creating good queries for reporting and business intelligence applications. Pro Oracle SQL also helps you minimize parsing overhead, read execution plans, test for correct results, and exert control over SQL execution in your database. Youll learn when to create indexes, how to verify that they make a difference, how to use SQL Profiles to optimize SQL in packaged applications, and much more. YoullÂ also understandÂ how SQL is optimized for working in sets, and that the key to getting accurate results lies in making sure that queries ask clear and precise questions.
