Write a program in PL/SQL to retriev the records from the employees table and display them using cursors

DECLARE
  z_empid employees.employee_id%TYPE;
  z_empname employees.first_name%TYPE;
  z_salary employees.salary%TYPE;
  CURSOR employee_cursor IS  -- declaring a cursor
    SELECT employee_id,
           first_name,
           salary
    FROM   employees;

BEGIN
  OPEN employee_cursor;    -- opening the cursor
  LOOP
    FETCH employee_cursor  -- fetching records from the cursor
    INTO  z_empid,
          z_empname,
          z_salary;
    EXIT
  WHEN employee_cursor%NOTFOUND;
    IF (z_salary > 8000) THEN
      dbms_output.Put_line(z_empid
      || '   '
      || z_empname
      || '   '
      || z_salary);
    ELSE
      dbms_output.Put_line(z_empname
      || ' salary is less then 8000');
    END IF;
  END LOOP;
  CLOSE employee_cursor;  --closing the cursor
