Use a database schema with the seven case tables (see Appendix C of this book) to perform the following exercises. The answers are presented in Appendix D. 1. 2. 3. 4. 5. 6. For all employees, provide their last name, a comma, followed by their initials. For all employees, list their last name and date of birth, in a format such as April 2nd, 1967. On which day are (or were) you exactly 10,000 days old On which day of the week is (was) this Rewrite the example in Listing 5-23 using the NVL2 function. Rewrite the example in Listing 5-24 to remove the DECODE functions using CASE expressions, both in the SELECT clause and in the ORDER BY clause. Rewrite the example in Listing 5-20 using DATE and INTERVAL constants, in such a way that they become independent of the NLS_DATE_FORMAT setting.

In this chapter, you will learn how to change the contents of an Oracle database. The SQL commands to change the database contents are commonly referred to as Data Manipulation Language (DML) commands. The first four sections of this chapter cover the DML commands INSERT, UPDATE, DELETE, and MERGE. The first three commands have names that are self-explanatory. The fourth one, MERGE, allows you to perform a mixture of insertions, updates, and deletions in a single statement, which is especially useful in data warehousing environments without using a procedural language like PL/SQL.

Note Many of the commands in this chapter modify data that is used in later chapters. It is important to issue the ROLLBACK commands indicated in this chapter or to recreate the tables and data before continuing to 7.
In production environments, especially when dealing with high-volume transactions, data manipulation is mostly performed via database applications. In general, these database applications are built (or generated) with application development tools such as Oracle Forms and Oracle JDeveloper. Such applications offer a pleasant user-friendly interface to the database; however, they still use the basic INSERT, UPDATE, and DELETE commands under the hood to communicate with the database, so you should understand how these commands work. Additionally, sometimes manual data manipulation via SQL*Developer and SQL*Plus can be very efficient. For example, you may want to perform global updates (such as to change a certain column for all rows of a table at the same time) or to remove all rows of a table. Following are some of what we ll cover in this chapter: In the first section (Section 6.1) we will introduce the INSERT command, which is used to populate tables with data. The second section (Section 6.2) introduces the UPDATE command that modifies data that is already in a table. Section 6.3 explains how to remove data from tables using DELETE. Section 6.4 introduces the MERGE statement, which is used to either INSERT or UPDATE data depending on the rules you define. Section 6.5 explains the concept of transactions and introduces three transactionrelated SQL commands: COMMIT, SAVEPOINT, and ROLLBACK.This chapter is also the
