Help w/ SQL Statement - Finding what's NOT on a table

I have 3 tables setup: admin, site, adminsite.

I use the unique id fom admin and site to populate the adminsite table. I am looking for a SQL statement that will allow me to pull all of admins that are NOT listed on the adminsite table.

Can anyone lend a hand with this?

Thanks
Marcus

Figured it out:

SELECT *
FROM ADMIN
WHERE not exists (select * from SITEADMIN Where ADMIN.A_ID = SITEADMIN.admin_id);

It would help to know how the tables are related, but you can try this

Code:

SELECT *
FROM Admin
WHERE AdminID NOT IN
(
   SELECT DISTINCT AdminID
   FROM AdminSite
)
