DAD 220 Module Four Major Activity Database Documentation Template Complete these steps as you work through the directions for this activity. Replace the bracketed text with your screenshots and brief explanations of the work they capture. Each screenshot and its explanation should be sized to approximately one quarter of the page, with the description written below the screenshot. Follow these rules for each of the prompts and questions below. Review the example document for assistance. Follow steps 1 through 4 from the Module Three Major Activity only to generate tables for this assignment. 1. Import the data from each file into tables. a. Use the import utility of your database program to load the data from each file into the table of the same name. You will perform this step three times, once for each table. b. Provide the SQL commands you ran against MySQL to complete this successfully in your answer: a. LOAD DATA INFILE '/home/codio/workspace/orders.csv' INTO TABLE Orders FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 1 ROWS; i. Press Enter b. LOAD DATA INFILE '/home/codio/workspace/rma.csv' INTO TABLE RMA FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 1 ROWS; i. Press Enter c. LOAD DATA INFILE '/home/codio/workspace/customers.csv' INTO TABLE Customers FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n' IGNORE 1 ROWS; i. Press Enter 2. Write basic queries against imported tables to organize and analyze targeted data. For each query, include a screenshot of the query and its output. You should also include a brief, 1-3 sentence description of the output. a. Write an SQL query that returns the count of orders for customers located only in the city of Framingham, Massachusetts. a. select Customers.CustomerID, City, State FROM Customers inner join Orders on Orders.CustomerID = Customers.CustomerID WHERE City = 'Framingham' AND State = 'Massachusetts'; i. Press Enter

I was given the order ID’s of 505 customers who are all located in Framingham, Massachusetts. The inner join shows all these ID’s paired with the specified location. b. Write an SQL query to select all of the customers located in the state of Massachusetts. i. Use a WHERE clause to limit the number of records in the customers table to only those that are located in Massachusetts. ii. Record an answer to the following question: How many records were returned? a. select Customers.CustomerID, City, State FROM Customers inner join Orders on Orders.CustomerID = Customers.CustomerID WHERE State = 'Massachusetts'; i. Press Enter The commands I used give the order ID’s of 982 customers who are all located in Massachusetts. The inner join shows all these ID’s paired with the specified state. c. Write an SQL query to insert four new records into the orders and customers tables using the following data: i. Customers Table CustomerID FirstName Lastname StreetAddress City State ZipCode Telephone 100004 Luke Skywalker 17 Maiden Lane New York NY 10222 212-555-1234 100005 Winston Smith 128 Sycamore Street Greensboro NC 27401 919-555-6623 100006 MaryAnne Jenkins 2 Coconut Waay Jupiter FL 33458 321-555-8907 100007 Janet Williams 58 Redondo Beach Blvd Torrence CA 90501 310-555-5678

a. INSERT INTO Customers VALUES (100004, 'Luke', 'Skywalker', '17 Maiden Lane', 'New York', 'NY', '10222', '212-555-1234'), (100005, 'Winston', 'Smith', '128 Sycamore Street', 'Greensboro', 'NC', '27401', '919-555-6623'), (100006, 'MaryAnne', 'Jenkins', '2 Coconut Waay', 'Jupiter', 'FL', '33458', '321- 555-8907'), (100007, 'Janet', 'Williams', '58 Redendo Beach Blvd', 'Torrence', 'CA', '90501', '310-555- 5678'); i. Press Enter This command tells MySQL to insert new values into a table called Customers . Rather than perform 4 seperate queries to insert 4 rows of data, I used parenthesis to distinguish between each new attribute to be added into the table. ii. Orders Table OrderID CustomerID SKU Description 1204305 100004 ADV-24-10C Advanced Switch 10GigE Copper 24 port 1204306 100005 ADV-48-10F Advanced Switch 10 GigE Copper/Fiber 44 port copper 4 port fiber 1204307 100006 ENT-24-10F Enterprise Switch 10GigE SFP+ 24 Port 1204308 100007 ENT-48-10F Enterprise Switch 10GigE SFP+ 48 port a. INSERT INTO Orders VALUES (1204305, 100004, 'ADV-24-10C', 'Advanced Switch 10GigE Copper 24 Port'), (1204306, 100005, 'ADV-48-10F', 'Advanced Switch 10 GigE Copper/Fiber 44 port copper 4 port fiber'), (1204307, 100006, 'ENT-24-10F', 'Enterprise Switch 10GigE SFP+ 24 Port'), (1204308, 100007, 'ENT-48-10F', 'Enterprise Switch 10GigE SFP+ 48 port'); i. Press Enter This command works in the same way the previous one did. The only difference between these two queries (Aside from the values themselves) is which table these attributes are being added into. Rather than Customers , we have Orders to populate. d. In the customers table, perform a query to count all records where the city is Woonsocket, Rhode Island.

The answer is 7 customers are located in Woonsocket, Rhode Island. I used the COUNT function to select all customers with these conditions and return the numeric value without me having to count them myself. a. SELECT COUNT(*) FROM Customers WHERE City = 'Woonsocket' AND State = 'Rhode Island'; i. Press Enter i. How many records are in the customers table where the field “city” equals ‘Woonsocket’? The answer is still 7. This is beacuse there is only one state in the Customers table with a city named ‘Woonsocket’. a. SELECT COUNT(*) FROM Customers WHERE City = 'Woonsocket'; i. Press Enter e. In the rma database, update a customer’s records. i. Write an SQL statement to select the current fields of status and step for the record in the rma table with an orderid value of ‘5175’. 1. What are the current status and step?

The current status is ‘Pending’ and the step is ‘Awaiting Customer Documentation’. a. select status, step FROM RMA WHERE OrderID = 5175; i. Press Enter ii. Write an SQL statement to update the status and step for the orderid , 5175 to status = ‘Complete’ and step = ‘Credit Customer Account’ 1. What are the updated status and step values for this record? - Provide a screenshot of your work. a. UPDATE RMA SET status = 'Complete', step = 'Credit Customer Account' WHERE OrderID = 5175; i. Press Enter b. select status, step FROM RMA WHERE OrderID = 5175; i. Press Enter The UPDATE command is simple way to easily modify values stored in a table. The above query tells MySQL which table will be updated, what columns to look under, and what new values to include in their respective rows only where the OrderID = 5175. f. Delete rma records. i. Write an SQL statement to delete all records with a reason of ‘Rejected’. 1. How many records were deleted? Provide a screenshot of your work. According to MySQL, there are 0 rows with a reason of ‘Rejected’. Before performing the DELETE command, I used a select statement to ensure I would be deleting the correct rows and got a response

back of ‘Empty set’. I also tried lowercase ‘rejected’ and still got ‘Empty set’. I ran the delete query regardless to show that I know how to delete rows, but it seems as though there were never any ‘Rejected’ orders in RMA to begin with. I also only ran the DELETE query once. a. DELETE FROM RMA WHERE Reason = 'Rejected'; i. Press Enter 3. Create an output file of the required query results. Write an SQL statement to list the contents of the orders table and send the output to a file that has a .csv extension. a. select OrderID, CustomerID, SKU, Description FROM Orders into outfile'/home/codio/workspace/New_Orders_Table.csv' FIELDS TERMINATED BY','; i. Press Enter
