Practical SQL: The Sequel - Tapa blanda

Sinopsis

In the real world, the SQL challenges you're likely to face go far beyond the "generic" basics taught by most books. Whether you're maintaining existing SQL code, enhancing it, or writing entirely new applications, you need to review all kinds of SQL, understand what's going on "under the hood," and translate SQL's features into real tools for solving problems. In Practical SQL: The Sequel, Judith Bowman builds on her best-selling Practical SQL, delivering techniques and code you can use right now to write queries that solve even your most complex problems. Organized around categories of problems -- not abstract SQL features -- Practical SQL: The Sequel includes extensive proven code that has been tested against multiple leading RDBMS systems. Bowman offers detailed solutions for controlling data displays using character, number, and date functions; cleaning dirty data; and translating values using a variety of methods. There's a full chapter on managing multiples. Finally, Bowman presents numbering solutions, and techniques for tuning queries. An extensive sample database is included, along with a single source reference containing information about leading SQL dialect variants. For every intermediate-to-advanced level database and business professional who wants to use SQL more effectively.
