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.
