cim.saddleback.edu has a MySQL/MariaDB database available for you. We hand in all assignment using the submit command. Pay attention to what each assignment query is asking, computers do what you say not what you want. Almost all assignments also have a corresponding Canvas quiz, the quiz and assignment name always match. In all pre-book assignment you also have a set of matching videos.

Each assignment description has three parts:

1. Objectives of Assignment
2. Synopsis concise steps with links for completing assignment
3. Checklist Completion Steps which is a detailed description of how to complete assignment.

To complete this class simply begin at the first assignment work top - down. The Canvas Welcome announcement has all key due dates; submit lists exact due dates of assignments. Quizzes expire on due dates, assignment have a 9 hour grace period. After that you can turn in assignments up to 7 days late with a 25% penalty, after that you can submit assignments at half credit. Exception, last day of class is last day of class. You cannot turn in assignments more than 9 hours after the last day of class. Key to success in any on-line course is too stay up with the work. In this logic oriented class whereby material builds on itself, you need to both stay up with the work and master the work. You need to understand the tutorial.sql videos before progressing to the next level.

I will be sending out e-mail reminders informing where you should be in the course. You can always complete the course early. Once again complete all assignments in order they listed (i.e., top down).

• phpMyAdmin is mapping all functions names to upper case but we use all lowercase function names for submit
• all function arguments have a space before and after (we use sum( price ) not sum(price)
• for fruit database all tables are lower case
• for fruit tables all field names are lower case except for ID, (i.e., fruitID)
• you should use accent marks to delimit table and field names
• never include database names in your queries, we will always first select a database.
• in checklist completion steps we use roman numbers to count identify Canvas videos.

If you have submit errors you can wait until you complete the next assignment select.sql, which goes into identifying submit errors.

Consistency notes:

• Nota Bene Premiere Database uses all Upper-Case letters for both table and field names.'
• Premiere Database is used in both the book and the corresponding book assignments.
• Fruit database tables are all lower-case letters. Fruit used medial caps, for table names consisting of two words, 2nd words start with capital letters.
• Premiere is using underscores to separate multi-word table or field names.
• Function names and arguments are lower case.
• all filenames for book start with p then page number then .sql

checklist:

• Watch Canvas Textbook webcast
• Read chapter 1
• Hand write the answers to the 10 updated questions extracted from page 21.
• Take chapter 1 Canvas quiz
• Take assignment one Canvas quiz
• Assignment one Canvas quiz has all SQL queries for submitting p21.sql, if you can submit p21.sql or wait until you cover chapter 3.

submit p58.sql (7 Points) phpMyAdmin
Read chapter 2, use one of your Databases for fruit (such as DBusername) and other database for Premiere (such as DB1username. Once you have selected your premiere database, delete all existing tables and use phpMyAdmin import tab, (aka Import Tab, premiere → premiereCreate.sql). You can also download the create script at /home/premiere/public_html/premiereCreate.sql (Right^Click to Save), and then import your local copy using phpMyAdmin It is also advantageous to use the phpMyAdmin designer tab to create a graphic schema. We have an existing schema at https://cim.saddleback.edu/~premiere. After you have created the premiere database, submit p58.sql consisting of these seven Queries:

1) Display names of all the premiere database tables;
2) Display the number of customers you have.
3) List the contents of the CUSTOMER table.
4) Describe the REP table.
5) List the contents of the ORDERS table.
6) List contents of REP table, sorted by highest commission first.
7) Display customer name with highest credit limit, hint select customer_name, order by, limit 1;

You should probably use phpMyAdmin to help you create the queries, especially the sorted ones.

checklist

• read chapter 2
• take Canvas chapter 2 quiz
• submit p58.sql

Read chapter 3, submit p87.sql phpMyAdmin

For p87.sql, tables already exists (pma import premiere) for submit complete these queries:

1. #Display the first five rows in ORDER_LINE table.
2. # Display all your customer names along with their city and state.
3. #How many salesman do you have?
4. # Display the contents of PART Table
5. # Describe the PART table
6. # display contents of PART table ordered by increasing price
7. # what is the total value of all orders, display as "Top Line Revenue"
8. what is price of most expensive part display as "Highest Priced Item"
9. # display REP Last Name, Customer Name, Balance and credit limit, for all customers sort lexicographically by reps last name, then by customer name
10. # display order number and order date of all orders associated with Juan Perez, order by order numbers descending

You can keep submitting until you have 10/10, if you don't fix one query at a time

checklist

• take Canvas chapter 3 quiz
• submit p87.sql
• submit p21.sql

Read Chapter 4; submit p125.sql. (21 Points) phpMyAdmin
Write MySQL commands to solve questions 1..21 on page 125. Proceed each command with a comment specifying the question number.

on Question 7 make sure you include both end points 10 and 25 and do this only one way.

Hint on question 20, you need to do a group by rep number right after the from table statement and then use a having clause with sum( balance ). Note the having clause enables the group by clause to be used as a where conditional, in this case sum(balance) refers to the sum of the balance relative to the group by REP_NUM. To sort the final output, just end the query with order by REP_NUM.

checklist

• read chapter 4
• take Canvas chapter 4 quiz
• submit p125.sql

phpMyAdmin

Read Chapter 5; Chapter 5 on multiple tables is one of the hardest chapters; submit p157.sql, (20 Points) this consists of all Premiere Database queries, questions 1..20 pages 157-158, the following questions have further clarification:

• Question 5 on all sub-queries you should return only one column, returning multiple columns is often logically incorrect. With the current version of MariaDB this mistake is causing both phpMyAdmin and submit to hang. You should be doing all initial testing in phpMyAdmin, submit is for submitting not debugging.
• Question 6 list customer number and customer name for all customers with active orders that were not placed on 2007-10-21.
• Question 8 the sort order becomes order by class, ORDERS.order_num and then ORDER_LINE.part_num;
• Question 9, find rep number, rep last name, and rep first name, of reps who represent a customer with credit limit of exactly 5000.
• Question 11 you may need to add order by CUSTOMER_NUM DESC.
• Question 12 # hint you will need to combine the part table with itself, look for the matching classes and display parts number in ascending order; Sort the output by the first part_num table, then by the second part_num table, You are displaying PART_NUM, DESCRIPTION from first table, then PART_NUM, DESCRIPTION, and CLASS from second table. If still stuck, reread the section "Joining a Table to Itself" pages 140-141 and pay special attention to the Q&A sidebar on page 141.
• Question 13, make sure you include the single quote.
• Question 15 order by order_num ASC; Hint put select after union in parentheses, then add order by clause
• Question 16 MySQL does not have the intersect operator just use an and in the where clause. You can also consider using or having.
• Questions 20 order by part number, then by order number both in ascending order.
• Preface each MySQL command with the question number comment line.

Hints Do not even attempt to try to join more than three tables, use sub queries first to determine customer_num from customer_name, and part_num from description.

checklist

• read chapter 5
• take Canvas chapter 5 quiz
• submit p157.sql
• Verify your quiz grades on Canvas by clicking quiz Grades button

Chapter 6 is relatively easy; submit p177.sql; - phpMyAdmin

Write a SQL query for questions 1-10; Question 8 is two queries, 8 and 8b; Also added four display content of Table:NONAPPLIANCE queries, 2a, 5a, 7a and 9a. Note #2a, #5a, #7a, #9a and #8b are the five additional queries added to this assignment, The final Query list is:

1. # 1 create table 'NONAPPLIANCE' do not prefix table name 'NONAPPLIANCE' with your database - table fields are PART_NUM, DESCRIPTION, ON_HAND, CLASS and PRICE. These will have the same types as other tables have for these columns.
2. # 2 insert into NONAPPLIANCE all items that are not class 'AP'; For this one you need to use insert select command., You will be inserting into the table NONAPPLIANCE, using a select from table: PART. Nota Bene submit cannot verify correct output for 1 and 2. Insert, create, update, delete have limited output so submit can not verify them. However, #2a (aka 3), will fail, if either 1 or 2 are wrong.
3. #2a Display contents of NONAPPLIANCE sort by ascending Price
4. #3 change description of PART_NUM AT94 to Deluxe Iron
5. #4 increase price of all items CLASS SG by 2%
6. #5 add Part number TL92 description Trimmer, units on hand 11, class HW, price 29.95
7. # 5a display contents of NONAPPLIANCE Table
8. # 6 delete every part in NONAPPLIANCE of class SG
9. # 7 in NONAPPLIANCE change PART_NUM FD21 to CLASS NULL
10. #7a display contents of NONAPPLIANCE Table
11. # 8 Add new last Column ON_HAND_VALUE seven digit number with 2 decimal points to NONAPPLIANCE table
12. # 8b set all values of column ON_HAND_VALUE to ON_HAND*PRICE in table:NONAPPLIANCE
13. # 9 in NONAPPLIANCE table increase column DESCRIPTION to 30 characters
14. # 9a display contents of NONAPPLIANCE Table
15. # 10 Remove NONAPPLIANCE Table
