Above query is syntactically correct and kindly explain why you mentioned it is not working either it is not returning the expected results or something else..

FYI, above query is trying to get list of all professor names whose salary is higher than 4 times the minimum salary across all professors.
If you want to calculate something else, kindly let us know so that we can help modify the query..

a query which returns no rows works
a query which gives a syntax error doesn't work

if it didn't work, what error did you get ?

It appears you want anyone making more than 4 times the minimum salary.

Every time you think you need to select from the same table again, especially in an inline query, stop and rethink it.

See if this works for you:
SELECT Professor_Name, Salary from (
	SELECT Professor_Name, Salary, min(salary) over() * 4 four_time_min FROM SALARIES
) salaries
where salary > four_time_min

With all the new questions, I understand you are learning SQL.  The WINDOW functions are very powerful once you understand the syntax and what they are doing.

I suggest spending some time in the documentation and other online examples.
