I have these tables

MANAGEMENT.PAYMENTS
PaymentID
PatientID
AdvancePayment
FinalPayment
PaymentStatus

FACILITIES.WARDDETAILS
WardID
WardName
Ward_Charge

PATIENTS.PATIENTDETAILS
PatientID
Discharge_Date
Admit_Date
Ward_ID

Pls how do i validate

1)FinalPayment should store the final amount chargeable and must be calculated as
Total Bill - AdvancePayment
3)The total bill will be calculated at time of discharge by adding the ward charges for the number of days the patient was admitted to the ward

Hello
I guess about ManagementPayment, is one per patient per session.

not tested


select patientID
, datediff(d,discharge_Date,Admit_date) * Ward_Charge as [Total Bill]
, datediff(d,discharge_Date,Admit_date) * Ward_Charge-coalesce(AdvancePayment,0) as FinalPayment
from Patients.PatientDetails as PD
inner join Facilities.WardDetails as WD
on PD.Ward_ID=WD.Ward_ID
inner join Management.Payments MP
on PD.PatientID=MP.PatientID
