assignment #3 solution
Unless prior arrangements are made, homework turned in late will not be accepted. However, homework turned in within 24 hours late will be graded at 50% credit.
Please note that only TEXT files will be accepted. All other file types (e.g., DOC, DOCX, RTF, PDF, JPG, or ZIP) will be rejected. In D2L, only the most recent submission is kept.
If you modified the DEPARTMENT and EMPLOYEE tables created in Assignment #1, you need to delete and re-populate them.
Do not try to use complicated joins or subqueries to get the results. You can solve the questions quickly by using multiple PL/SQL statements.
You are not allowed to create temporary tables, views, functions, or procedures.
The EXCEPTION section is NOT allowed in your programs.
Please review your file before submitting it to make sure you have the correct one. It is your responsibility to upload the correct file.

The table baby_name consists of some popular given names for male and female babies born during the years 1915-2014. Rank 1 is the most popular, rank 2 is the next most popular, and so forth.
Create and populate the baby_name table as described below.
CREATE TABLE baby_name
( RANK NUMBER(3),
SEX CHAR CONSTRAINT ck_sex CHECK (SEX in ('M', 'F')),
GIVEN_NAME VARCHAR2(20) NOT NULL,
NUMBER_OF_OCCURRENCES NUMBER NOT NULL,
CONSTRAINT pk_baby_names PRIMARY KEY (RANK, SEX));
/
INSERT INTO baby_name SELECT * FROM hchen.baby_name;
COMMIT;
/
SELECT COUNT(*) FROM baby_name;
/
Please make sure that there are 24 rows in your baby_name table.
You cannot change the definition of the baby_name table. You will receive 0 points if you use different tables.
Write a PL/SQL anonymous block that accepts a positive integer n from the user input and displays all rows (Sex, Rank, Given Name, and Number_of_Occurrences) having rank ≤ n in the baby_name table. Sort your output in ascending order by sex, and then rank.
The sex column (“M” or “F”) must be displayed as “Male” or “Female” in your output. You will lose 5 points if you fail to do so.
CSC 452: your program displays “Male” and “Female” only once in the Sex column.
To avoid complicating issues, you can assume that the user always enters input from keyboard that consists only of the digits 0 through 9, plus (+) or minus (-) sign, and Enter. But, you need to check whether the user input is a positive number or not.

Based on the tables created in Assignment #1, write a PL/SQL anonymous block to perform the following tasks:
Display the number of employees in the company.
Display the maximum/minimum/average total pay for the company.
For each department, perform the following steps:
Display the department ID, name and location.
Display 80% of the maximum total pay (maximum total pay * 0.80) for the department.
Display 111% of the minimum total pay (minimum total pay * 1.11) for the department.
Display the average total pay for the department.
If the department does not have any employees, (b), (c) and (d) will be $0.00.
If the average total pay for the department is greater than (b) and less than (c), the department name is marked with “***”.
Sort your output in ascending order by department ID.
Total Pay = Salary + Commission.
You must display the maximum/minimum/average total pay with a dollar ($) sign, a comma, and two decimal places (e.g., $1,234.56). You will receive 0 points if you use hard-coded department names (e.g., Accounting, Research).

The table auto_service consists of auto repair and maintenance information. Create and populate the auto_service table as described below.
CREATE TABLE auto_service
(
SERVICE_ID NUMBER(10) PRIMARY KEY,
VIN VARCHAR2(18) NOT NULL,
SERVICE_DATE DATE NOT NULL,
SERVICE_PRICE NUMBER(7, 2) NOT NULL,
NOTE VARCHAR2(200) NOT NULL
);
/
INSERT INTO auto_service SELECT * FROM hchen.auto_service;
COMMIT;
/
SELECT COUNT(*) FROM auto_service;
Please make sure that there are 20 rows in your auto_service table.
You cannot change the definition of the auto_service table. You will receive 0 points if you use different tables.
(A vehicle identification number, commonly abbreviated to VIN, is a unique code used by the automotive industry to identify individual motor vehicles.)
To avoid complicating issues, assume that:
For each VIN, there can be at most one service on any day.
For each VIN, the service price is unique.
Write a PL/SQL anonymous block that performs the following task:
For each VIN in the auto_service table, if 1) the first service date is in the period 02/01/2004 (01-FEB-04) to 03/31/2013 (31-MAR-13), 2) the last service date is in the period 03/01/2012 (01-MAR-12) to 03/31/2013 (31-MAR-13), and 3) the number of services is larger than 2, the following items along with the VIN are displayed:
The total number of services
The first service date and the service price for the first service
The last service date and the service price for the last service
The minimum service price and the service date for the minimum service price
The maximum service price and the service date for the maximum service price
Hard coding the VIN being displayed (e.g., ABC123), the number of VIN being displayed (e.g., 2), or the number of services being displayed (e.g., 3, 4) will receive 0 points.
You must display the service price with a dollar ($) sign, a comma, and two decimal places (e.g., $1,234.56). Sort your output in ascending order by VIN.
(This question should take less than 50 minutes to solve.)
Hints: First service date – MIN(SERVICE_DATE)
Last service date – MAX(SERVICE_DATE)
Minimum service price– MIN(SERVICE_PRICE)
Maximum service price– MAX(SERVICE_PRICE)
The output of your program must match the following (one VIN per line):
Please submit a text file containing all the source codes to D2L by the due date.
Optional Question
Just for fun (no credit, no extra credit, no need to submit, just for if you are a curious person and like database programming).
In a bug tracking database, there is a table called BUGS. The table has several columns: BUG_ID, REPORTED_DATE, DESCRIPTION, PRIORITY, ASSIGNED_TO, CLOSED_DATE, and NOTE.
Create and populate the BUGS table.
CREATE TABLE bugs
(
BUG_ID NUMBER PRIMARY KEY,
REPORTED_DATE DATE NOT NULL,
DESCRIPTION VARCHAR2(20),
PRIORITY NUMBER(2),
ASSIGNED_TO VARCHAR2(10),
CLOSED_DATE DATE,

“Open Bugs” - A bug is considered open on a given day if (1) its “REPORTED_DATE” is on or before that day, and (2) its “CLOSED_DATE” is on or after that day (or is unknown (NULL)). For example, we have 5 open bugs on 5/5/2014.
Write a PL/SQL anonymous block that generates a report to show the number of open bugs from 5/1/2014 through 5/31/2014. Sort your output by the number of open bugs in descending order and then by the date in ascending order. At the end of the report, the maximum number of open bugs on a single day is displayed. Assume that there were no open bugs on 4/30/2014.
The output of your program should match the following:
Number of Open Bugs Date
9 14-MAY-14
9 15-MAY-14
9 25-MAY-14

---------------------------------------
The maximum number of open bugs on a single day is 9.
There were 9 open bugs on 14-MAY-14.
There were 9 open bugs on 15-MAY-14.
