The employees are not in PRESIDENT designated and salary is more than the highest paid employee of PERTH where no MANAGER and SALESMAN are working under KAYLING. Return complete information about the employees.

Sample table: employees

Sample table: department

Sample table: salary_grade

Sample Solution:

SELECT *
FROM employees
WHERE dep_id IN
    (SELECT dep_id
     FROM department
     WHERE department.dep_location ='SYDNEY')
  AND emp_id IN
    (SELECT emp_id
     FROM employees e,
          salary_grade s
     WHERE e.salary BETWEEN s.min_sal AND s.max_sal
       AND s.grade IN (3,
                       4,
                       5) )
  AND job_name != 'PRESIDENT'
  AND salary >
    (SELECT max(salary)
     FROM employees
     WHERE dep_id IN
         (SELECT dep_id
          FROM department
          WHERE department.dep_location = 'PERTH')
       AND job_name IN ('MANAGER',
                        'SALESMAN')
       AND manager_id NOT IN
         (SELECT emp_id
          FROM employees
          WHERE emp_name = 'KAYLING'));

Sample Output:

 emp_id | emp_name | job_name | manager_id | hire_date  | salary  | commission | dep_id
--------+----------+----------+------------+------------+---------+------------+--------
  67832 | CLARE    | MANAGER  |      68319 | 1991-06-09 | 2550.00 |            |   1001
