select * from employee
where salary > all (select salary from employees where departmen_id = 50);

this query gives us the records of having the salary greater than the maximum salary of subquery

Hi Sir, one request, once you explain a topic give a small exercise problem like homework on that topic.

In this case, if you select greater than all, it will mean that the salary should be greater than all three (provided we are using sub query for salary) !
