________________________________________
Lab 5 of 7: Retreiving data from Multiple Tables (28 points)
L A B O V E R V I E W
Scenario/Summary

Lab 5 deals with writing queries using multiple tables as covered in the reading and lecture material this week. In some cases, you will be given the option to write a query using either the TRADITIONAL method of joining tables or using the JOIN key word. In some cases, you will be asked to use a specific approach. Using the incorrect process when the process is specified will result in points being taken off for that problem.

The SELECT statement is the primary means of extracting data from database tables, and allows you to determine exactly which data you want to extract by means of different comparison operators used in the WHERE clause. This includes the use of specific "wild card" characters which allow you to search for character or number patterns within the data. You can also perform mathematical expressions within the SELECT statement to create derived output. The ORDER BY clause allows you to sort the output data in either ascending (the default) or descending order. Lab #5 will explore all of these applications of the SELECT statement.
General Lab Information and Considerations
This lab will utilize a set of tables found in the script file (LeeBooks.sql) found in the Doc Sharing area of the website. If you have not yet downloaded this file from Doc Sharing then do so now. Once you have downloaded the script file, import and run the script in SQL*Plus.
Each query in the script file you will create must be numbered (use --1 comments for numbering) and in…...

The editor interface to the Oracle server is SQL*Plus, and by now you have received your logon ID and password and should have at least made sure you can connect. If for any reason you have not done so, please do so now before continuing any further. If for any reason you cannot connect then you need to let the instructor know ASAP so that any problems can be resolved. Before attempting Lab #3, you need to be sure you have read through the SQL*Plus tutorial which can be found in Doc Sharing as well as under the SQL*Plus Tutorial tab in Week 3. This tutorial describes the functionality of the editor and will take you through the process of setting up and using the SQL*Plus in the iLab environment so that it will best serve your needs for the remainder of the labs required for this course. The lab for this week addresses taking a logical database design (data model) and now transforming that into a physical model (tables, constraints, and relationships). As part of the lab, you will need to download the Zip file titled “Lab 3 Support Documents” from Doc Sharing. This Zip file contains three......
