Chapter 4. Commands

Every interaction between a client and a data source, whether it is to retrieve information, delete a record, or commit a change, is governed by a Command object. In this chapter, we introduce the Command object in detail. You'll learn how to define a command and use it to execute nonquery commands such as direct record updates, insertions, and deletions. You'll also learn how to use parameterized commands and commands that access stored procedures.
