I was blown away! . . . Most SQL books sit on my shelf. This one will live on my desk.” –Roger Carlson, Microsoft Access MVP (2006-2015) “Rather than stumble around reinventing wheels or catching glimpses of the proper approaches, do yourself a favor: Buy this book.” ―Dave Stokes, MySQL Community Manager, Oracle Corporation Effective SQL brings together practical solutions and insights so you can solve complex problems with SQL and design databases that simplify data management in the future. It’s the only modern book that brings together advanced best practices and realistic example code for all of these versions of SQL: IBM DB2, Microsoft Access, Microsoft SQL Server, MySQL, Oracle Database, and PostgreSQL. Drawing on their immense experience as world-class database consultants and instructors, the authors identify 61 proven approaches to writing better SQL. Wherever SQL versions vary, the authors illuminate the key nuances, so you can get the most out of whatever version you prefer. This full-color guide provides clear, practical explanations; expert tips; and plenty of usable code. Going far beyond mere syntax, it addresses issues ranging from optimizing database designs to managing hierarchies and metadata. If you already know SQL’s basics, this guide will help you become a world-class SQL problem-solver. Craft better logical data models, and fix flawed models Implement indexes that improve query performance Handle external data from sources you don’t control Extract and aggregate the information you need, as efficiently as possible Write more flexible subqueries Analyze and retrieve metadata using your database platform of choice Use Cartesian Products and Tally Tables to solve problems you can’t address with conventional JOINs Model hierarchical data: managing SQL’s tradeoffs and shortcomings Review “Given the reputation of the authors, I expected to be impressed. Impressed doesn’t cover it, though. I was blown away! Most SQL books tell you ‘how.’ This one tells you ‘why.’ Most SQL books separate database design from implementation. This one integrates design considerations into every facet of SQL use. Most SQL books sit on my shelf. This one will live on my desk.” ―Roger Carlson, Microsoft Access MVP (2006-2015) “It can be easy to learn the basics of SQL, but it is very difficult to build accurate and efficient SQL, especially for critical systems with complex requirements. But now, with this great new book, you can get up to speed and write effective SQL much more quickly, no matter which DBMS you use.” ― Craig S. Mullins, Mullins Consulting, Inc., DB2 Gold Consultant and IBM Champion for Analytics “This is a great book. It is written in language that can be understood by a relative beginner and yet contains tips and tricks that will benefit the most hardened workhorse. It will therefore appeal to readers across the whole range of expertise and should be in the library of anybody who is seriously concerned with designing, managing, or programming databases.” ―Graham Mandeno, database consultant and Microsoft MVP (1996-2015) “This book is an excellent resource for database designers and developers working with relational and SQL-based databases―it’s an easy read with great examples that combine theory with practical examples seamlessly. Examples for top relational databases Oracle, DB2, SQL Server, MySQL, and PostgreSQL are included throughout. The book walks the reader through sophisticated techniques to deal with things such as hierarchical data and tally tables, along with explanations of the inner workings and performance implications of SQL using GROUP BY, EXISTS, IN, correlated and non-correlated subqueries, window functions, and joins. The tips you won’t find anywhere else, and the fun examples help to make this book stand out from the crowd.” ―Tim Quinlan, database architect and Oracle Certified DBA “This booBooks >> Subjects >> Computers & Technology >> Databases & Big Data
