I would use EXCEPT to build a select SQL statement - example at link below:

Give this a whirl, renaming the obvious
-- names not in name.locations 
SELECT t1.name
FROM Table1 t1
   LEFT JOIN Table2 t2 ON t1.name_id = t2.name_id
WHERE t2.location_id IS NULL

-- names not in name.locations for all locations
SELECT t3.name_id, t3.location_id,
FROM Table3 t3
   LEFT JOIN Table2 t2 ON t3.name_id = t2.name_id AND t3.location_id = t2.location_id
WHERE t2.location_id IS NULL

SQL Server expert chapmandew has an excellent article called SQL Server: Table Joins Explained! that spells out joins.  Also, search images.google.com for 'SQL table join' to get a wompload of pictures that describe JOIN behavior very nicely.

Here is your exception report:

select names.nameid, locations.locid
from names
CROSS JOIN locations
EXCEPT
SELECT nameid, locid
FROM name.locations
ORDER BY nameid, locid

Here you go:
SELECT n.nameid, l.locid
FROM names n
	CROSS JOIN locations l 
WHERE NOT EXISTS (SELECT 1 
		FROM name_locations nl
		WHERE n.nameid = nl.nameid AND l.locid = nl.locid)
ORDER BY n.nameid, l.locid

yes i did - however, your join for t3 fails as it doesn't have the column for name_id.  when i used phillip's response, it worked the first time... therefore, i went with his response.
