You could try something like
<cfquery name="combined" dbtype="query">
SELECT firstName, lastName
FROM query1
WHERE NOT EXISTS (
SELECT firstName, lastName
FROM query2
WHERE firstName = query1.firstName
AND lastName = query1.lastName
)
</cfquery>
No guarantees - this is standard SQL and would work with MySQL, but I'm not
sure it will work with a query-of-queries.
