Chapter 14: Fundamentals of Using Access SQL
IN THIS CHAPTER
Understanding basic SQL
Getting fancy with advanced SQL
Using SQL specific queries
Structured Query Language (SQL) is the language that relational database management systems (such as Access) use to perform their various tasks. In order to tell Access to perform any kind of query, you have to convey your instructions in SQL. Don't panic — the truth is, you've already been building and using SQL statements, even if you didn't realize it.
In this chapter, you'll discover the role that SQL plays in your dealings with Access and learn how to understand the SQL statements generated when building queries.

The basics you learn here will lay the foundation for your ability to perform the advanced techniques you'll encounter throughout the rest of this book.
