#10152
You have been asked to find the employees with the highest and lowest salary.
Your output should include the employee's ID, salary, and department, as well as a column salary_type that categorizes the output by:
- 'Highest Salary' represents the highest salary
- 'Lowest Salary' represents the lowest salary
table name: worker

table name: title

Solution:
with cte as(
select w.worker_id,w.salary,w.department ,
(case when w.salary = (select max(salary) from worker) then 'Highest Salary'
when w.salary = (select min(salary) from worker) then 'Lowest Salary'
else null
end) as salary_type
from worker as w
left join title as t on w.worker_id = t.worker_ref_id
)select * from cte where salary_type is not null
Output:
