SQL Queries for Mere Mortals has earned worldwide praise as the clearest simplest tutorial on
writing effective queries with the latest SQL standards and database applications. Now author
John L. Viescas has updated this hands-on classic with even more advanced and valuable
techniques. Step by step Viescas guides readers through creating reliable queries for
virtually any current SQL-based database. He demystifies all aspects of SQL query writing from
simple data selection and filtering to joining multiple tables and modifying sets of data.
Building on the basics Viescas shows how to solve challenging real-world problems including
applying multiple complex conditions on one table performing sophisticated logical evaluations
and using unlinked tables to think outside the box.” In two brand-new chapters students learn
how to perform complex calculations on groups for sophisticated reporting and how to partition
data into windows for more flexible aggregation. Students can practice all they need with
downloadable sample databases for today's versions of Microsoft Office Access Microsoft SQL
Server and the open source MySQL and PostgreSQL databases. Instructor Resouces include an
Instructor Guide PowerPoint slides and a TestBank
