CIS/336 iLab 6 of 7 - SQL Course
________________________________________

Oracle Single Row and Group Functions
L A B O V E R V I E W
Scenario/Summary
Lab #6 will introduce the various aspects of the Single-Row and Group Functions available in the Oracle Database. Most functions can be used in either the SELECT statement or the WHERE clause, but more commonly are used in the SELECT. Chapters 5 and 6 cover most all of the normal processing you use in these functions. In some cases, you will be asked to used more than one function within a single SELECT statement.
General Lab Information and Considerations
This lab will utilize the same set of tables found in the script file (LeeBooks.SQL) that were used for Labs 4 and 5.
Each query in the script file you will create must be numbered (use --1 comments for numbering) and in order. The SQL for the following exercises should be written using notepad and run in SQL*Plus. Read each problem carefully and follow the directions as stated.
A Clean Script File:
A script file is meant to be like a program. The file can be run every time the code needs to be executed without having to retype the code again each time. For this reason, it is important that there are no errors in the code inside the file. You can go back and forth between notepad and Oracle when creating your script file to check your queries and verify if they work or not. However, you do not want to create your final output file until after you have verified that everything in your script is correct by running it, in its entirety at least once and viewing the output. Once this has been done, you can create your final output file, with echo to create the…...

For instructions on how to use the Dropbox, please click here. L A B O V E R V I E W Scenario/Summary Lab #4 will introduce the various aspects of the SQL select statement and the methods of retrieving data from the database tables. The lab will utilize a set of tables found in the script file (LeeBooks.sql) found in the Doc Sharing area of the website. You will need to download the file, then run the script in your SQL*Plus session. These tables will be used for the remaining labs in this class. 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.......
