Table of Contents
In this Chapter, you will learn about:
PL/SQL Programming Fundamentals
In the first two chapters you learned about the difference between machine language and a programming language. You have also learned how PL/SQL is different from SQL and about the PL/SQL basic block structure. This is similar to learning the history behind a foreign language and in what context it is used. In order to use the PL/SQL language, you will have to learn the key words, what they mean, and when and how to use them. First, you will encounter the different types of key words and then their full syntax. Finally, in this chapter, you will expand on simple block structure with an exploration of scope and nesting blocks.
