Hi,

I have write down following query ..

select a.patientid, a.providerid
from PatientDrugList a
JOIN Admin..Loadinstance b on a.intLoadInstanceId = b.intLoadInstanceId
where a.MailReasonTypeId = -1
and b.SubClientId = 22
and b.StatusTypeId > 0

Now how could I get distinct patientid count and distinct providerid count

Reply soon

Reading Books Online makes me wanna try

select count(distinct a.patientid), count(distinct a.providerid)
from PatientDrugList as a
inner JOIN Admin..Loadinstance as b on b.intLoadInstanceId = a.intLoadInstanceId
where a.MailReasonTypeId = -1
and b.SubClientId = 22
and b.StatusTypeId > 0
