Hi,

I have two tables:

Contact (id,name) Link (id, contact_id, source_id)

I have the following query which works that returns the contacts with the source_id of 8 in the Link table.

SELECT name FROM `Contact` LEFT JOIN Link ON Link.contact_id = Contact.id WHERE Link.source_id=8;

However I am a little stumped on how to return a list of all the contacts which are NOT associated with source_id of 8. A simple != will not work as contacts without any links are not returned.

Thanks.
