A Step by Step Guide to Learning SQL

Written for readers who have little or no previous experience with databases, SQL, or Microsoft SQL Server database software, this book provides a systematic approach to learning SQL (Structured Query Language) using SQL Server database software. It starts with simple SQL concepts, and progresses to more complex query development. Each chapter is written in a step-by-step manner and has examples that can be executed using SQL Server. Using the sample database, readers can experience hands-on SQL programming in SQL Server. This text also presents exercises at the end of the chapters to help readers gain proficiency in SQL.
