ON CS.Client_Name = CL.Client_Name
//could you plz check my joins are accurate or not ,here are also distinct Facility_Name

(not images of data! data in a reusable format)

plz find the correct way something as below using row number and partition
INSERT INTO Patient (
Patient_Id ,MPI ,First_Name ,Middle_Name ,Last_Name ,
Patient_Suffix ,Age ,Birth_Date ,Gender ,SSN ,Upd_Date ,User_Id )
SELECT CCST.Patient_Id , CCST.MPI , CCST.First_Name , CCST.Middle_Name , CCST.Last_Name , CCST.Patient_Suffix , CCST.Age , CCST.Birth_Date , CCST.Gender , CCST.SSN , CCST.Upd_Date , CCST.User_Id
FROM (
SELECT Patient_Id ,MPI ,First_Name ,Middle_Name ,Last_Name ,
Patient_Suffix ,Age ,Birth_Date ,Gender ,SSN ,Upd_Date ,User_Id
ROW_NUMBER() OVER (PARTITION BY Patient_Id ORDER BY Upd_Date DESC
) rownumber
FROM CCareStageTbl
) CCST
WHERE rownumber = 1
it is a good lesson to have learned, nice job
