5.1. Introduction

Previous chapters provided tables in the examples that had already been created and populated with data. But what if you need to create a table, populate it with data, or delete rows of data or tables that are no longer needed or wanted?

In this chapter, the numerous discussions and examples focus on the way tables are created, populated and deleted. These are important operations and essential elements in PROC SQL, especially if you want to increase your comprehension of SQL processes and improve your understanding of this powerful language.
