Chapter 7 Simple Data Manipulation
Simple data manipulation is a programming technique used to SELECT or
INSERT a single row. It can also be used to INSERT, DELETE, or UPDATE
one or more rows based on a specific criterion. These types of data
manipulation operations are considered simple because they can be done
with SQL data manipulation commands that:
* Are not executed in conjunction with a cursor. Therefore
additional SQL commands such as FETCH and OPEN are not required.
* Are not dynamically preprocessed. Therefore the amount of code
required to execute them is minimized.
This chapter reviews how to use the SELECT, INSERT, DELETE, and UPDATE
commands for simple data manipulation. It then examines transaction
management considerations that are relevant to simple data manipulation.
Finally, this chapter examines two programs that illustrate simple data
manipulation.
