Beginning Oracle SQL 3rd下载

This is not a book about advanced SQL. It is not a book about the Oracle optimizer and diagnostic tools. And it is not a book about relational calculus, predicate logic, or set theory. This book is a SQL primer. It is meant to help you learn Oracle SQL by yourself. It is ideal for self-study, but it can also be used as a guide for SQL workshops and instructor-led classroom training. This is a practical book; therefore, you need access to an Oracle environment for hands-on exercises. All the software that you need to install Oracle Database on either Windows or Linux for learning purposes is available free of charge from the Oracle Technology Network (OTN).
