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. Had to redo the entire module three assignment, even though when I would use the command select databases; the QuantigrationRMA would show up on there, but it showed that I had no tables, even though I had completed the tables before. I think due to the issues that I am having with the “access denied”, and being unable to change permissions my previous assignments aren’t fully saving. I’ve been having to redo previous assignments for every module. & it is taking me significantly longer to get any assignments done. 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. 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'; LOAD DATA INFILE '/home/codio/workspace/rma.csv' INTO TABLE RMA FIELDS TERMINATED BY ',' LINES TERMINATED BY '\r\n'; B. Provide the SQL commands you ran against MySQL to complete this successfully in your answer.

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. i. How many records were returned? 505 records were returned. Used the command: Select COUNT(*) from Customers where City = 'Framingham' AND State = 'Massachusetts';

Running the command to select the count from the customers. Included the city and state to get an exact location of what I was looking for which was to find the customers in a specific location. By combining the need of what I was looking for with the city and state I was able to get the query that 505 records came from Framingham, Massachusetts. 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? 982 Records returned. I used the command: SELECT COUNT(*) FROM Customers WHERE UPPER(Customers.state) = 'MASSACHUSETTS'; I wrote the sql to determine the number of customers in a state. In order to do this I had to make sure to specify the exact state I was searching the records for. Since I was looking in Massachusetts as a whole state I took out the city from the sql from the previous command. The end result gave me 982 customer records for the state of Massachusetts. 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 Way Jupiter FL 33458 321-555-8907 100007 Janet Williams 58 Redondo Beach Blvd Torrence CA 90501 310-555-5678 INSERT INTO Customers (CustomerID, FirstName, LastName, Street, City, State, ZipCode, Telephone) VALUES (100004, 'Luke', 'Skywalker', '15 Maiden Lane', 'New York', 'NY', '10222', '212-555-1234'), (100005, 'Winston', 'Smith', '123 Sycamore Street', 'Greensboro', 'NC', '27401', '919-555-6623'), (100006, 'MaryAnne', 'Jenkins', '1 Coconut Way', 'Jupiter', 'FL', '33458', '321-555-8907'), (100007, 'Janet', 'Williams', '55 Redondo Beach Blvd', 'Torrence', 'CA', '90501', '310-555-5678'); Followed the usual command to insert information into a table. Made sure to put in the same order as the customers table was sorted in originally. By checking this before I used the command show Customers; which did populate every customer and I had to scroll all the way up to make sure the information I was entering was accurate. Since in the table above it says to StreetAddress I made sure to change it to street only in the command since that is what it shows on that table. Then proceeded to

add the new customers into the table. Selected customers using their individual ID’s to make sure they populated 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 INSERT INTO Orders (OrderID, CustomerID, SKU, Description) VALUES (1201305, 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');

To be able to enter the correct command again I double checked to make sure I described the orders to know what information to gather and make sure it was accurate with the descriptions above. Since I was OrderID, CustomerID, SKU, and Description I was able to use that to write the command needed. I then carefully entered the information in. At first I put ‘ ‘ around the CustomerID and had to redo it and take ‘ ‘ out from around the customer ID to get the right results. I then used the select Orders command with the OrderID numbers to make sure that they were inserted and populated correctly. D. In the Customers table, perform a query to count all records where the city is Woonsocket, Rhode Island. i. How many records are in the customers table where the field “city” equals “Woonsocket”? Used Command: Select COUNT(*) from Customers where City = 'Woonsocket' AND State = 'Rhode Island'; Used the command that I also used in step 2 but changed the state and city. Since the city and state were different, I changed the information in the command to reflect what I was looking for. The result that I got was 7 records. 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?

Using the Command: SELECT * FROM RMA WHERE OrderID = 5175; Which populated the RMA and OrderID stating that it is awaiting customer documentation the status is pending and the reason is that it is defective. 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.

Used the first Command UPDATE RMA SET Status = ‘Complete’, Step = ‘Credit Customer Account’ WHERE OrderID = 5175; to change the status of both the status and the step. Then used the command SELECT FROM * RMA WHERE OrderID = 5175; to check to make sure that the status and step changed. 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

Used the command DELETE FROM RMA WHERE Reason = ‘Rejected’; Using this command, selected all the RMA sets that had been rejected which was 596 rows and removed them from this database. In order to check to see if there was anymore rejected RMA’s I used the command SELECT(*) COUNT FROM RMA WHERE Reason = ‘Rejected’; This showed me that there was a 0 count on rejected RMA’s. 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.

Using this command which we had used in a previous model to get a CSV file I was able to save this table with each row of the orders. This way I am able to pull up just a csv file of all orders vs having to write a command for each order to get the information that may be needed for a business.
