Oracle Database 11g SQL P1

Today’s database management systems are accessed using a standard language known as Structured Query Language, or SQL. Among other things, SQL allows you to retrieve, add, update, and delete information in a database. In this book, you’ll learn how to master SQL, and you’ll find a wealth of practical examples. You can also get all the scripts and programs featured in this book online (see the last section, “Retrieving the Examples,” for details).
