Greetings,
I have the following tables:
Table A
UUID
Computer_Name

Table B
UUID
ProcedureUUID

Table C
ProcedureUUID
SW_Name

I have the following query which shows me all instances where SoftwareX is install on a system:

SELECT * 
FROM A JOIN B ON A.UUID = B.UUID 
JOIN C ON B.ProcedureUUID= C.ProcedureUUID
WHERE SW_Name like 'SoftwareX'

I would like to be able, in one result set, to identify not only those systems that have SoftwareX installed but also system that do not.

[code]
SELECT *
FROM A JOIN B ON A.UUID = B.UUID
LEFT JOIN C ON B.ProcedureUUID= C.ProcedureUUID
AND SW_Name like 'SoftwareX'
[/code]

I appreciate the help but that is not a solution to this query. That does not necessarily identify all records from Table A that may not be in Table B or Table C.

What I have come up w/ however that does appear to work is the following:

SELCT *
(SELECT * 
FROM A JOIN B ON A.UUID = B.UUID 
JOIN C ON B.ProcedureUUID= C.ProcedureUUID
WHERE SW_Name like 'SoftwareX') AS DRV1
RIGHT OUTER JOIN A on DRV1.Name = A.Name
