Select 'ONLY = TO'


A

ainese

I have a table with ESN and SERVICE TYPE and SUBSCRIBER TYPE. ESN can
appear more than once depending on the number of services associated.
Each service type has a charge.

To date I have the below code - where i'm trying to count esn where
service type is only = basic and not equal to data push or
tracking....


SELECT Count(F.ESN) AS ["Basic Activations"]
FROM Data AS F
INNER JOIN Data AS G ON (F.ESN= G.ESN AND F.SERVICE= "Basic" AND
G.SERVICE <>"Data Push" AND G.SUBSCR_TYPE = "Service Activation")
WHERE G.ESN NOT IN
(SELECT ESN FROM Data WHERE SERVICE = 'Tracking');


I added G.SERVICE <> "Data Push" but with the inner join I'm getting
some duplicates of 'Data Push' due to the
INNER JOIN


How do I omit them,


Can anyone advise me on how to do this please?


Thanks
