Which interviewer asked you this question?

SET ROWCOUNT 1

SELECT * FROM Employees ORDER BY Salary DESC

SET ROWCOUNT 0

try this. It does not use TOP, any aggregate function, ORDER BY.


declare @salary int, @max_salary int
declare c cursor for select Salary from employee
open  c 
fetch next from c into @salary
set @max_salary = @salary
while @@fetch_status = 0
begin
	if @salary > @max_salary select @max_salary = @salary
	fetch next from  c into @salary
end 
close c
deallocate c
select	@max_salary as [max salary]
