SQL Problem

[Tony Evans]

This is a SQL not a java problem, if someone could point me towards a SQL website similar to this i would be happy or if you can solve this problem I would be even happier.
I have two tables EMPLOYEE and WORKING, I want to display all employees mot working. I use the folling SQL Code>
select emp.employeeID, emp.name
from EMPLOYEE emp,WORKING wk
where wk.employeeID != emp.employeeID

What it returns is all employees not working plus all the employees. So I am getting two lots of data returned.
e.g if Tom Smith is working, James Thomas and Sara Hall are not I get returned
James Thomas
Sara Hall
Tom Smith
James Thomas
Sara Hall
I used to know how to solve this problem but I have forgotten.
Thanks for any help.

Tony,
You need a subquery:

select emp.employeeID, emp.name
from EMPLOYEE emp
where emp.employeeId not in 
(select wk.employeeId from WORKING wk where wk.employeeId = emp.employeeId)
