SQL Queries for Mere Mortals: A Hands-On Guide to Data Manipulation in SQL
Editorial Reviews

To the people who are accomplished in its use, Structured Query Language (SQL) is a highly capable, eminently flexible, even beautiful way of describing the data that you want from a database, or the changes that you want to make to a database. For the rest of us, however, SQL is a first-class nuisance that we do our best to avoid by relying on relatively user-friendly--but usually less powerful--tools. SQL Queries for Mere Mortals aims to bring SQL-phobes closer to the first camp by tutoring them carefully in what SQL can do.
The authors recognize that SQL queries usually come about as a result of questions from human beings, and so usefully spend a fair bit of time showing how to convert, say, "In what cities do our customers live?" into, "Select city from the customers table" and, finally, "SELECT city FROM customers" in SQL. They call this the "translation and clean up" process, and it's a fine approach. They don't press it too far, however, and are equally adept at presenting straight explanations of SQL syntax elements in prose. They spend a lot of energy graphically diagramming aspects of SQL syntax in a format that requires some up-front study. A particular reader might prefer text capsules to this arrow-intensive format, but other learners might like the graphical syntax diagrams. --David Wall
Topics covered: ANSI SQL/92 for people who need to use it to make queries against business databases. The authors introduce one or two syntax elements at a time--SELECT, WHERE, JOIN, UNION, and so on--and cover data extraction, data insertion, filtering, joins, calculations, and other capabilities of generic SQL.
