Effective SQL: 61 Specific Ways to Write Better SQL(Effective Software Development Series)

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-colour guide provides clear, practical explanations; expert tips; and plenty of usable code. Going far beyond mere syntax, it addresses issues ranging from optimising database designs to managing hierarchies and metadata.

John L. Viescas is an independent database consultant with more than 45 years of experience. He began his career as a systems analyst, designing large database applications for IBM mainframe systems. He spent six years at Applied Data Research in Dallas, Texas, where he directed a staff of more than 30 people and was responsible for research, product development, and customer support of database products for IBM mainframe computers. While working at Applied Data Research, John completed a degree in business finance at the University of Texas at Dallas, graduating cum laude.

John joined Tandem Computers, Inc., in 1988, where he was responsible for the development and implementation of database marketing programs in Tandem’s U.S. Western Sales region. He developed and delivered technical seminars on Tandem’s relational database management system, NonStop SQL. John wrote his first book, A Quick Reference Guide to SQL (Microsoft Press, 1989), as a research project to document the similarities in the syntax among the ANSI-86 SQL standard, IBM’s DB2, Microsoft’s SQL Server, Oracle Corporation’s Oracle, and Tandem’s NonStop SQL. He wrote the first edition of Running Microsoft® Access (Microsoft Press, 1992) while on sabbatical from Tandem. He has since written four editions of Running, three editions of Microsoft® Office Access Inside Out (Microsoft Press, 2003, 2007 and 2010—the successor to the Running series), and Building Microsoft® Access Applications (Microsoft Press, 2005). He is also the best-selling author of SQL Queries for Mere Mortals®, Third Edition (Addison-Wesley, 2014). John currently holds the record for the most consecutive years being awarded MVP from Microsoft, having received the award from 1993-2015. John makes his home with his wife of more than 30 years in Paris, France.

Douglas J. Steele has been working with computers, both mainframe and PC, for almost 45 years. (Yes, he did use punch cards in the beginning!) He worked for a large international oil company for more than 31 years before retiring in 2012. Databases and data modeling were a focus for most of that time, although he finished his career by developing the SCCM task sequence to roll Windows 7 out to over 100,000 computers worldwide.

Recognized by Microsoft as an MVP (Most Valuable Professional) for more than 16 years, Doug has authored numerous articles on Access, was co-author of Access Solutions: Tips, Tricks, and Secrets from Microsoft Access MVPs (Wiley Publishing, 2010), and has been technical editor for a number of books.

Doug holds a master’s degree in systems design engineering from the University of Waterloo (Ontario, Canada), where his research centered on designing user interfaces for non-traditional computer users. (Of course, this was in the late ’70s, so few people were traditional computer users at the time!) This research stemmed from his background in music (he holds an associateship in piano performance from the Royal Conservatory of Music, Toronto). He is also obsessed with beer, and is a graduate of the brewmaster and brewery operations management program at Niagara College (Niagara-on-the-Lake, Ontario).

Doug lives with his lovely wife of more than 34 years in St. Catharines, Ontario. Doug can be reached at AccessMVPHelp@gmail.com.
