Exercise 7

Write a PL/SQL block that declares and uses two cursorsone without a parameter and one with a parameter. The first cursor retrieves the department number and the department name from the departments table for all departments whose ID number is less than 100. The second cursor receives the department number as a parameter, and retrieves employee details for those who work in that department and whose employee_id is less than 120.

Exercise 8

Declare a cursor dept_cursor to retrieve department_id and department_name for those departments with department_id less than 100. Order by department_id. Open dept_cursor and use a simple loop to fetch values into the variables declared.

Exercise 9:

Based on Exercise 8, display the department number and department name. Use the appropriate cursor attribute to exit the loop.
