Hey Colin,
why don't you just list all the data you need in the SELECT section and the
tables that are necessary for the select in the FROM section?
What I mean is to write:
SELECT DISTINCT C.id,
C.name,
C.parent_channel AS parent_id,
C.label AS channel_label,
(SELECT COUNT(P.package_id)
FROM rhnChannelPackage P
WHERE P.channel_id = C.id
) AS package_count,
CA.name AS arch_name
FROM rhnChannel C
inner join rhnChannelArch CA ON CA.ID = C.channel_arch_id
inner join rhnUserChannel UC ON UC.channel_id = C.id
left join rhnChannel C2 ON C2.parent_channel = C.id
WHERE UC.user_id = :user_id AND
(C.org_id = :org_id OR ( C2.id IS NOT NULL AND C2.org_id = :org_id
))
instead of:
select Distinct C.id,
C.name,
C.parent_channel as parent_id,
C.label as channel_label,
(SELECT COUNT(P.package_id)
FROM rhnChannelPackage P
WHERE P.channel_id = C.id
) AS package_count,
(select CA.name from rhnChannelArch CA where CA.ID =
C.channel_arch_id) arch_name
from rhnChannel C inner join
rhnUserChannel UC on UC.channel_id = C.id left join
rhnChannel C2 on C2.parent_channel = C.id
where UC.user_id = :user_id AND
(C.org_id = :org_id or ( C2.id is not null AND C2.org_id = :org_id
))

Tomas
