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.
