SQL Select where not exists?

(Simplified)
I have a view with the following 4 fields

ClientID   ContactID    ContactType   FullName


I want to do a UNION all and
Select  ClientID, ContactID,ContactType,FullName
From ClientContacts

Where the ClientCOntacts record doesn't exist in the View

The similar fields are of course ClientID and ContactID

select  ClientID, ContactID, ContactType, FullName
from ClientContactsView C
union all
select  ClientID, ContactID, ContactType, FullName
from ClientContacts C
where not exists (
  select 1
  from ClientContactsView C1
  where C.ClientID = C1.ClientID and C.ContactID = C1.ContactID
)

Open in new window
