Solution 1

Your query might be something like

SQL

select * from employees A where salary > (select max(salary) from employees where employeeType = 'clerk')

Probably correct as OP is not very precise in expressing himself. 5+
See my my comment on gaurav's answer. :)

Saw it Manfred :).

From what the OP has asked Gaurav's answer appears correct - honestly though, I too doubt that was what he meant to ask.

Solution 2

I think the requirement is Salary higher than all clerk's

So it should be

Select * From Employees where Salary > (Select Sum(Salary) From Employees where EmployeeType = 'Clerk')

Reading OP's question I tend to agree with you (5+) eventhough OP probably meant to say "... than the salaray of any clerk ...".
Cheers!
