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’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. Above are the commands used to enter the .csv files into the already established tables I had. The FIELDS TERMINATED and LINES TERMINATED BY statements both give the tool the guidelines for how it input the data, making sure two values or more don’t end up in one column.

Above I used the SELECT COUNT() statement with each tables primary key in order to pull the total amount of records in each table without having duplicates because of using the primary key. 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?

I got 505 records using the SELECT COUNT clause I was able to just be returned a total number rather than all 505 rows of data. From there I just put the WHERE clause to narrow my results to the city and state that I wanted results for. 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 Record an answer to the following question: How many records were returned? I got 982 records here using the same clause from before, but instead of specifying the city I only did the state to get me everyone in that 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 Way Jupiter FL 33458 321-555-8907 100007 Janet Williams 58 Redondo Beach Blvd Torrence CA 90501 310-555-5678 I just used our basic INSERT INTO clause we have been using in the previous labs to input all of these values into the already established 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

Again using the same INSERT INTO clause from previous labs I just added the values given into the already established table. 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”? I got 7 records back for customers in Woonsocket. I again used the SELECT COUNT clause to be retuned the number of customers who’s city = Woonsocket. 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 step is Awaiting customer Documentation. I used again a SELECT statement here with only the two columns of information I wanted returned and then put the WHERE clause to narrow it down to only that OrderID I was looking for. 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. After using the UPDATE RMA Set clause I was able to update both the status and step of orderID 5175. From there I used a SELECT clause again to pull the record to make sure that I correctly updated it. 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.

Here using the DELETE FROM clause I was able to delete all records with the specific parameter of WHERE Reason = Rejected. Which deleted 595 records from RMA. 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. Here I used the SELECT * to capture all records in Orders and from there I outputted into a .csv. Then I put the parameters with FIELDS TERMINATED BY and LINES TERMINATED BY to make sure each value is separated by commas and that there is only 1 record in each row.
