Thanks Edward,
But that gives me ALL records in persons that have any ONE record in phone.
What I want is ONLY those records in persons that do NOT have a
corresponding 'PHN' record in phone?
Thanks again.

SELECT * FROM person, phone
WHERE person.id = phone.id
AND phone.type != 'PHN';

Hi,
I'm not sure how to write this. Can you help pls?
I have 2 tables
persons & phone
persons has a 1->M with phone on personID.
phone can contain 3 'type' records relating to a person; 'EML', 'PHN', 'FAX'
I want to select _only_ those records in person which do NOT have a 'type'
'PHN' record in phone. Do I need a "NOT HAVING" or a "NOT IN" or...
Basically I don't know how to write the WHERE section of the call.
Can you help pls?
