Assignment : Troubleshooting SQL Statements

Assignment : Troubleshooting SQL Statements
In this assignment, you will delve deeply into Structured Query Language (SQL)
statements. You will review existing SQL statements and troubleshoot them. You would
need to determine why the given statements are not functioning properly. At the
conclusion of this assignment, you should be able to examine and troubleshoot basic
SQL statements.
A good friend of yours is starting a fantasy football league and has created a small
database to track the team owners, teams, players, and games. Your friend knows that
you are taking a database fundamentals class and has asked you to help. Your friend is
not able to figure out why the database is not getting modified in any way. Your friend has
given you a copy of the following: A database schema diagram. Click here to access the database schema
diagram. A Microsoft Access database. Click here to access the Microsoft Access
database. The following list of what he or she is trying to do:
1. Add a new owner named Alice Wonderland with an owner ID of 1205 and
a contact e-mail of [email protected]
VALUES (1205, 'Wonderland', 'Alice', '[email protected]') 2. Update player 323's salary to $1,800,000
salary = 1800000
WHERE player_id = 323 3. Display all players whose salary is greater than $1,000,000
WHERE salary 1000000 4. Delete owner Jerry Jones from the database
last_name = "Jones" AND first_name = "Jerry" 5. Update game 0105 with the final score
SET home_score = 17, visitors_score = 23 Note: For this assignment, you will use Microsoft Access 2010 to open the database file
provided. If you do not have Microsoft Access 2010, you may download a free trial
version of Microsoft Office 2010, which includes Microsoft Access 2010, from the
Microsoft website.
1. Open the Microsoft Access file "Football.accdb" by double-clicking on it. You will
see the small database created for the fantasy football league.
2. Familiarize yourself with the database by opening and examining the data in
each table.
3. There are two queries included with the database that will display some of the
information contained in the tables. Double-click each of these to see the results
of the query.
Once you are familiar with the database, proceed to the next section.
A. Examine and Correct the Faulty SQL Statements
1. For each SQL statement listed above, identify the SQL statement errors.
2. Once you have identified the errors, rewrite the SQL statements so that
they will work.
Note: Take special precautions with Statement 5 above. If you run the statement
as it is written above, you will overwrite the scores of all of the existing games in
the database.
B. Execute the Statements
1. On the Create tab, in the Queries group, click Query Design.
2. When prompted to add tables, click the Close button.
3. On the Query Tools Design tab, in the Results group, click on the down
arrow below the word View and select SQL View. This is where you will
compose your SQL statements. Feel free to type the statements above
into the SQL View window and run them (see Step 4) to view the errors.
(Note: Take special precautions with Statement 5 above. If you run the
statement as it is written above, you will overwrite the scores of all of the
existing games in the database.)
4. To run your SQL statements against the database, click the Run button in the Results group. You will be prompted to confirm that you want to
modify data in your database. Click Yes. Close the query and save it as
"Statement n", where n is the statement number listed above. For
example, you will save the first statement as "Statement 1".
5. Repeat this process for each SQL statement provided above.
6. Once you have completed correcting the SQL statements, save and exit
the database.
Save your database as M4_A2_Lastname_Firstname.accdb.
C. Explain the SQL Statement Errors
1. Create a Microsoft Word document explaining what was wrong with each
of the five originally written SQL statements. Include any additional
comments that you might have about the statements.
Save your document as M4_A2_Lastname_Firstname.doc.
Submission Details: Save your deliverables as By Wednesday, July 19, 2017, submit both the files to the M4 Assignment 2
Dropbox. Assignment 2 Grading Criteria Maximum
