I have a query that counts the number of training modules a user has sat. This works fine but I want it to be able to list the names aof all users who have not yet sat a course. Query I am using is:

SELECT pps_principals.name AS principals_name,
COUNT(*) AS coursecount
FROM (PPS_SCOS JOIN PPS_TRANSCRIPTS ON PPS_SCOS.SCO_ID = PPS_TRANSCRIPTS.SCO_ID)
JOIN PPS_PRINCIPALS ON PPS_TRANSCRIPTS.PRINCIPAL_ID = PPS_PRINCIPALS.PRINCIPAL_ID
AND PPS_TRANSCRIPTS.TICKET not like 'l-%'
and pps_scos.name like 'MT%'
GROUP BY pps_principals.name
HAVING COUNT(*) = 0

The principals.name is the user name. Scos.name being the course name. This query returns no rows at all.

SELECT
	pps_principals.name AS principals_name
FROM 
	PPS_PRINCIPALS join PPS_TRANSCRIPTS on PPS_TRANSCRIPTS.PRINCIPAL_ID = PPS_PRINCIPALS.PRINCIPAL_ID
	Left Join PPS_SCOS on PPS_SCOS.SCO_ID = PPS_TRANSCRIPTS.SCO_ID
Where
	PPS_SCOS.SCO_ID is NULL and
	AND PPS_TRANSCRIPTS.TICKET not like 'l-%'
	and pps_scos.name like 'MT%'
