DAD 220 Module Four Major Activity Database Documentation 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’ll 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. Commands: LOAD DATA INFILE '/home/codio/workspace/rma.csv' INTO TABLE RMA FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'; LOAD DATA INFILE '/home/codio/workspace/customers.csv' INTO TABLE Customers FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'; LOAD DATA INFILE '/home/codio/workspace/orders.csv' INTO TABLE Orders FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'; 2. Write basic queries against imported tables to organize and analyze targeted data . 3. For each query, include a screenshot of the query and its output. You should also include a 1- to 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. Commands: SELECT COUNT(*) FROM Customers INNER JOIN Orders on Customers.CustomerID = Orders.CustomerID WHERE UPPER(Customers.city) = 'FRAMINGHAM' AND UPPER(Customers.state) = 'MASSACHUSETTS'; Explanation:

The reason for this query was to find all customers located in Framingham, Massachusetts. I found that 505 orders populate with the provided command. An INNER JOIN ensures only customers with orders in the provided city and state are in the result. 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. Commands: SELECT COUNT(*) FROM Customers WHERE UPPER(Customers.state) = 'Massachusetts'; ii. Record an answer to the following question: How many records were returned? 982 records were returned. Explanation: This query required me to select all the customers from Massachusetts. The UPPER function changes all state names to upper case eliminating upper/lower case issues. Utilizing a WHERE clause I was able to limit the number of records from the table Customers to those only located in Massachusetts. C. Write an SQL query to insert four new records into the Orders and Customers tables using the following data: INSERT INTO Customers (CustomerID, FirstName, LastName, Street, City, State, ZipCode, Telephone) Values (100004,'Luke','Skywalker','17 Maiden Lane','New York','NY','1022','212-555-1234'), (100005,'Winston','Smith','128 Sycamore Street','Greensboro','NC','27401','919-555-6623'), (100006,'MaryAnne','Jenkins','2 Coconut Way','Jupiter','FL','33458','321-555-8907'), (100007,'Janet','Williams','58 Redondo Beach Blvd','Torrance','CA','90501','310-555-5678'); SELECT * from Customers where CustomerID IN (100004, 100005, 100006, 100007);

I utilized ‘street’ in my command and was able to add four new customers records to the table. Orders Table OrderID CustomerID SKU Description 1204305 100004 ADV-24-10C Advanced Switch 10GigE Copper 24 port 1204306 100005 ADV-48-10F Advanced Switch 10GigE 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

INSERT INTO Orders (OrderID, CustomerID, SKU, Description) VALUES (1204305, 100004, 'ADV-24-10C','Advanced Switch 10GigE Copper 24 port'), (1204306, 100005, 'ADV-48-10F','Advanced Switch 10GigE 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'); SELECT * from Orders where OrderID IN (1204305, 1204306, 1204307, 1204308); Explanation: In this question I was asked to add four Orders to the Orders table. D. In the Customers table, perform a query to count all records where the city is Woonsocket, Rhode Island. Explanation: Utilizing SELECT COUNT from the table Customers and the WHERE clause for city and state helped me achieve my solution. i. There are 7 records in the customers table where the field “city” equals “Woonsocket”.

E. In the RMA database, update a customer’s records. 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 status is Pending and the step is Awaiting customer Documentation. Explanation: The results from order 5175 show that progression of the process is dependent on the customer providing the required Documentation. the customer must provide the required information. Command: SELECT * FROM RMA WHERE OrderID = 5175; ii. Write an SQL statement to update the status and step for the OrderID , 5175 to status = “Complete” and step = “Credit Customer Account.” Command: UPDATE RMA SET Status = 'Complete', Step = 'Credit Customer Account' WHERE OrderID = 5175; 1. What are the updated status and step values for this record? The updated status is now Complete, and the Step is Credit Customer Account. Commands: UPDATE RMA SET Status = 'Complete', Step = 'Credit Customer Account' WHERE OrderID = 5175; SELECT * FROM RMA WHERE OrderID = 5175;

Explanation: To update the status and step of record 5175 an UPDATE statement was used. ‘Credit Customer Account’ and ‘Complete’ are the new step and status. This is verified with a SELECT command from the RMA table WHERE OrderID is 5175. Commands: UPDATE RMA SET Status = 'Complete' 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. The total number of records deleted is 596. Explanation: The DELETE command deletes all records from the RMA table WHERE ‘Rejected’ is the Reason. This deleted 596 records. My second command verifies deletion of the records by searching for records whose Reason is ‘Rejected’ returning with zero records. Commands: DELETE FROM RMA WHERE Reason = ‘Rejected’; SELECT COUNT(*) FROM RMA WHERE Reason = 'Rejected';

4. Create an output file of the required query results . 5. Write an SQL statement to list the contents of the orders table and send the output to a file with a .csv extension. Command: SELECT * INTO OUTFILE '/home/codio/workspace/quantigrationrma-data.csv' FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n' FROM Orders; Explanation: With this command I was able to create a file where this data will have structured data with easier to lien breaks. This is for use in applications such as Excel. The quantigrationrma-data.csv is now in the filetree.
