Write a SELECT statement that returns all rows with salary, last name, street address and ZIP code (SALARY, LAST_NAME, STREET, ZIP_CODE) from the EMPLOYEE and ADDRESS tables, sorted by SALARY from largest to smallest. STREET and ZIP_CODE are in the ADDRESS table, while the other fields are in the EMPLOYEE table. The common key is EMPLOYEE_ID.
3. Write a SELECT statement that joins the Departments, Courses, and Instructors tables. This statement should return these columns: DepartmentName, CourseDescription, FirstName, and LastName.
Use aliases for the tables and return only those courses with three units. Each course description should only be listed once.
Sort the result set by DepartmentName and then by CourseDescription in ascending sequence.
