Overview
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 the screenshots capture. Size each screenshot and its explanation to fit approximately one-quarter of the page with the description written below the screenshot. Review the Template Screenshot Example linked in the guidelines and rubric for this assignment to see how screenshots for your assignment should look.
Before you begin, follow steps one through four from the Module Three Major Activity Guidelines and Rubric only
to generate tables for this assignment. Then follow the steps below to complete the activity.
Organize and Analyze Data in Tables
1.
Import the
data from each file
into tables. A.
Use the Quantigration RMA database, the three tables you created, and the three CSV files preloaded into Codio.
B.
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.
i.
Reference notes for this step: Import the CSV File into the MySQL table. Use the following line terminators when importing: \r\n. Do not use IGNORE 1 LINES for data that does not have column headers in the first row.
C.
Provide the SQL commands you ran against MySQL to complete this step successfully.
EXPLANATION: In this picture, I started by using the ‘
mysql’
command in order to run the code asked in this assignment. It is seen that I have forgotten to select the Quantigration RMA by using ‘
use
QuantigrationRMA
;’ I then used the import utility tool to load the data onto the code to perform this step successfully three different times.
2.
Write basic queries against imported tables to organize and analyze targeted data. For each query you run in this step, include a screenshot of the query and its output. Also, include a one- to three-sentence explanation.
A.
Write a SQL query that returns the count of orders for customers located only in Framingham, Massachusetts. i.
This query will use a table join between the Customers and Orders tables. The query will also use a WHERE clause.
ii.
Record an answer to the following question: How many records were returned?
EXPLANATION: I have ran the following in order to get this result: “
select * FROM Customers INNER JOIN Orders ON Orders.CustomerID = Customers.CustomerID where City = 'FRAMINGHAM' AND State = 'MASSACHUSETTS'\G”. At the end, the total number of records that were returned were 505. To organize the data into a neater output, I ended my command with \G instead of;
B.
Write a SQL query to select all of the customers located in Massachusetts.
i.
Use a WHERE clause to limit the number of records in the Customers table to only those who are located in Massachusetts.
ii.
Record an answer to the following question: How many records were returned?

EXPLANATION: 982 rows of records were returned. As seen in the code written: “select * FROM Customers where State = 'Massachusetts'\G;” The ‘INNER JOIN’ has been removed as well as ‘City =’ as neither were asked for this section. I have once again used ‘\G;’ To organize my response
C.
Write a SQL query to insert four new records into the Orders and Customers tables using
the data below.

EXPLANATION: I wrote my command by trying to add the 4 different customers from the assignment. Everything went smooth until I go to MaryAnne. It seems that it didn’t match anything so I left it as it is. Pretty weird. The last one went as smooth as the first 2.
Orders Table
OrderID

Enterprise Switch 10GigE SFP+ 48 port
EXPLANATION: Same procedure as before, but this time everything went smooth. Instead of ‘Customers’
wrote instead ‘Orders’.
D.
In the Customers table, perform a query to count all records where the city is Woonsocket and the state is Rhode Island.
i.
How many records are in the Customers table where the field "city" equals "Woonsocket"? EXPLANATION: From all the records I got to pulled from this, 7 records were pulled.
E.
In the RMA database, update a customer's records.
i.
Write a 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?

EXPLANATION: Reached a roadblock for some reason. I couldn’t load the desired command to get a result, and I have tried this in different ways as well.
UPDATE: After some tries, I figured out the name of the column was OrderID, not Order_ID. The status is
set to pending and the step is Awaiting customer Documentation. I also noticed I accindently had ‘step’ as ‘stop’. A typo was made.
ii.
Write a 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.
EXPLANATION: The typo has been confirmed, ‘step’ is ‘stop’. I had to first updated the account information by changing the status to complete. After this was accomplished, I used the same code to pull the account information, but this time with the updated information.
F.
Delete RMA records.
i.
Write a SQL statement to delete all records with a reason of "Rejected".
1.
How many records were deleted? Provide a screenshot of your work.
EXPLANATION: After running this query, 596 rows were affected/deleted.
3.
Create an output file of the required query results
. 4.
Write a SQL statement to list the contents of the Orders table and send the output to a file that has a .csv extension.
EXPLANATION: The output was created, which I have labeled “orders2.cvs”. I then quit out of the ‘mysql’ and returned to the Linux command prompt. Since it would be a lot of files, I just pulled the output name to see if it existed or not, which now does.
