Finally a book for the true SQL Server beginner! Whether you are brand new to data bases and are thinking of getting your 70-461 certification or already a semi-pro working in the field and need some fingertip support, this is this is the book for you. Joes 2 Pros does not assume you already know anything about data bases or SQL server. The Author, Rick Morelan, started out as a true beginner after he decided he had had enough of working on a fishing boat in Alaska. Rick struggled for years to acquire the knowledge necessary just to get his foot in the door. Many years later as an instructor, who was not happy with the instructional material available for his SQL students, he began the process of creating his own material. In 2009 Rick released his first book, "Beginning SQL Joes 2 Pros: The SQL Hands-On Guide for Beginners" for SQL 2008. Due to its clear writing style, easy to follow images and free downloadable labs it quickly became a top seller on Amazon. This book builds on the success of the previous series and will help anyone transform themselves from a beginner "Joe" into a SQL 2012 "Pro". For those of you who have read the 2008 series for the 70-433 Exam you will find a lot of the same material from the SQL 2008 book in this SQL 2012 book. This is because much of the 70-461 test covers the same material as the 70-433. I have added material that is new to the test and removed material that is no longer relevant. If you have already read this series or have already passed the 70-433 exam you may choose to read my book which covers only the changes from 70-433 to 70-461 entitled "Joes 2 Pros SQL 2012 Queries 70-461 Exam for SQL 2008 Pros".
