Hi There
I think it would be better if you could provide us the format of output required.
Anyway try this:
SELECT A.Area, B.DeliveryName, A.Item, A.Description
FROM
TableA A inner join TableB B ON (A.Area = B.ColId) or (A.Area is NULL)
order by A.Area desc
Output:
---------
AreaDeliveryNameItemDescription
A4Acme4B4352Whatits
A1Acme1B1232Thingymebobs
NULLAcme1B8769Dunno
NULLAcme4B8769Dunno
NULLAcme8B8769Dunno
NULLAcme9B8769Dunno
Not sure if this is what you need ! 🙂
