Part II(60 points)

Your SQL statements can only reference the DEPARTMENTtable and/or EMPLOYEE table. You are not allowed to create/access other tables/views.

1)  (CSC 352 – 20 points | CSC 452 – 10 points)

Write a SQL SELECT statement to display all jobs,the maximum salary for each job, the maximumtotal pay (salary + commission) for each job, and the total number of employees in each job. You must display the maximumsalary and total pay with a dollar ($) sign, a comma, and two decimal places (e.g., $1,234.56).(You will lose 5 points if you fail to do so.) Sort your outputin ascending orderby job. (Submitting more than one SQL statement will receive 0 points.)

Your statement’s output should match the following format:

JOB                                                MAXIMUM SALARY MAXIMUM TOTAL PAY TOTAL NUMBER OF EMPLOYEES

————————————————– ————– —————– ————————-

ANALYST                                            $3,000.00      $3,000.00                                 3

……

2)  (CSC 352 – 20 points | CSC 452 – 10 points)

If an employee does not have a manager, the manager’s name is shown as “——” and the manager’s hire date is shown as 01-JAN-3000in your output. The hire date must be displayed in the DD-MON-YYYY format (4-digit year). Sort your outputin ascending order by employee name.(Submitting more than one SQL statement will receive 0 points.)

Hints:   1) You may need to use an OUTER JOINand aSELF-JOIN.

     2) NVL(TO_CHAR(column_x, ‘DD-MON-YYYY’), ’01-JAN-3000′)

You cannot use hard-coded employee names (e.g., WHERE employee_name = ‘KING‘) in your programs.

Your statement’s output should match the following format:

EMPLOYEE ID EMPLOYEE NAME        EMPLOYEE JOB                                       EMPLOYEE HIRE DATE MANAGER NAME         MANAGER HIRE DATE

———– ——————– ————————————————– —————— ——————– —————–

       7876 ADAMS                PROGRAMMER                                         15-JAN-2003        SMITH                20-DEC-2001
