Do you feel overwhelmed by the complicated jargon and tech stuff that comes with SQL? If so, this is the book you've been looking for. Each of the various commands and data types are explained thoroughly in an easy to understand way. In addition to that, every SQL statement has an example shown right after it to make the process of learning SQL as simple as possible. This book is not only to be used by beginners but also intermediates as a referencing tool when needed.
I had a bit of SQL exposure five years ago. This was easy to read and understand, however in my opinion more practicable examples would have been great.
