I need to roll up my data to the ORG level. There are multiple physicians per ORG. every physician has names and datapoints associated with it. The result that I want is the sum of all datapoints per names rolled up to the org level.
Can someone please get me started on this?
here's what i tried:
select o.org,p.names,sum(p.datapoint)
from OrgPhysicianMappingtbl o
join PhysicianDatatbl p
on o.physician=p.physician
group by o.org,p.names

Answer 1

You can use GROUPING SETS:
select o.org, p.names, sum(p.datapoint)
from OrgPhysicianMappingtbl o
inner join PhysicianDatatbl p
on o.physician = p.physician
GROUP BY GROUPING SETS((o.org), (p.names))
see SQL Fiddle with Demo

Answer 2

Well!
SELECT o.org, p.names, sum(p.datapoint)
FROM OrgPhysicianMappingtbl o INNER JOIN PhysicianDatatbl p
ON o.physician = p.physician
GROUP BY o.org, p.names

Answer 3

select o.org,p.names,sum(p.datapoint)
from OrgPhysicianMappingtbl o
join PhysicianDatatbl p
on o.physician=p.physician
group by o.org,p.names with ROLLUP

Answer 4

Even this should work
SELECT org,names,TotalDP
FROM(
SELECT
o.org
,p.names
,TotalDP = SUM(p.datapoint) OVER(PARTITION BY o.org,p.names)
,Rn = ROW_NUMBER() OVER(PARTITION BY o.org,p.names ORDER BY (SELECT 1))
FROM OrgPhysicianMappingtbl o
JOIN PhysicianDatatbl p on o.physician=p.physician)X WHERE X.Rn = 1
