Sql Ebook: A Primer on SQL

Sql Beginners Ebook

Author's personal note

Welcome to the second edition of A Primer on SQL. The first edition was more popular than I had initially imagined. The overwhelming response and the many readers who wrote back with comments or a simple thanks, led me to putting efforts into making the second edition. There are many corrections and clarifications throughout the chapters, alongiwth two major changes. The introduction of using SQLite as an alternative DBMS in the text, and a new chapter on calculated fields. I hope that old and new readers find this text even more useful now in its presentation. I have tried to keep the spirit of the original text, a short introduction to the basics. As always, your questions, comments, criticism, encouragement and corrections are most welcome and you can e-mail me at rhlbatra[aht]hotmail[dot]com. Rahul Batra (24th February 2014) Preface to the first edition Welcome to the first edition of A Primer on SQL .
As you would be able to see,the book is fairly short and is intended as an introduction to the basics of SQL. No prior experience with SQL is necessary, but some knowledge of working with computers in general is required. My purpose of writing this was to provide a gentle tutorial on the syntax of SQL,so that the reader is able to recognize the parts of queries they encounter and even be able to write simple SQL statements and queries themselves.
Your questions, comments, criticism, encouragement and corrections are most welcome and you can e-mail me at rhlbatra[at]hotmail[dot]com. I’ll try answering all on-topic mails and will try to include suggestions, errors and omissions in future editions. Rahul Batra (8th October 2012)
