I have a table to that is updated from a history table. The update happens because on a join of tables linked by patient id and order number shown below. In a perfect world this works.
update
pharm.dbo.cms_dcmedorderimport
set cms_dcmedorderimport.rxno =
h.rxno,
cms_dcmedorderimport.rono =
h.rono
from rx..hrxs h
where cms_dcmedorderimport.cms_order_number =
h.orderid
and cms_dcmedorderimport.patientid = h.patid
Now the complex part, and orderid and a patient id are only unique within a group of locations. Both of the tables ablove have a 3rd field which is a facility id which joins to a facility table. And since some of these patients can move around within a location there is no 1 to 1 match for the facility id, just that the facility is part of that contract.
On the facility table there is a contractid if which several facilities will belong to. So I need my update where clause to also include to make sure that the orderid and patientid for the first table (cms_dcmedorderimport) link to the hrxs table and that for both tables the contractid would be the same

A little hard to help you. It would help if you could provide the DDL for the tables, sample data that is representative (made up) of your actual data, expected results based on this data.
As this appears to be medical related, I will emphasize using data that you make up but is representative of your problem.
If you need some help with this request, please read the first article in my signature block regarding asking for assistance.

No problem I get the HIPPA world.
patient table
patid
facid
hrxs table
patid
facid
rxno
orderid
facilities table
facid
contractid
in patients you could have
patid facid
122 100
122 234
facilities
facid contract
122 OKL
234 MIC
100 OKL
HRXS
patid facid orderid rxno
122 122 100 555
122 234 100 444
update
pharm.dbo.cms_dcmedorderimport
set cms_dcmedorderimport.rxno =
h.rxno,
cms_dcmedorderimport.rono =
h.rono
from rx..hrxs h
where cms_dcmedorderimport.cms_order_number =
h.orderid
and cms_dcmedorderimport.patientid = h.patid

Please read the article I suggested. Unless I want to take the time to write CREATE TABLE and INSERT statements, there really isn't much in your latest post that I can use directly.

If I've pieced this all together it looks like you want update a table using orderid and patientid however this give erroneous results due to the fact that combination (orderid/patientid) is only unique under a facilityid. In addition the facilityid has it's own issues because a patient could be moved to other facilities under a contractid.
So you couldn't you add the contractid to both your dcmedorderimport and hrxs tables, thereby updating the correct records?
If that's not a possibility, then you could cross join the facilities table to itself where the contractids are equal get all valid intracontract facility move combinations and add that table to your update statement.
With little to go on in the way of table structures and no final values of what you're expecting from your update statement; this is what I came up with.
