I have two tables:
Allowance [Account ID] key Claims [Account ID], [Claim #] key
I am querying the two via a inner join. I am using account ID to complete the join.The allowance table stores the alowance dollar amount [allowance amount] allocated for the account. There is one record per account. The claim table has the [dollar transactions] that has posted to the account. There are multiple transactions [dollar transactions] in the second table in relationship to the first [account].
How do I sum the [dollar transaction] by [Account Id] in the claims table? And display the difference (varaice) between the [dollar transaction] in the second table table and [account amount] in the fisrt table?
Here you go:
SELECT Allowance.AccountID, MAX(Allowance.AllowanceAmount) as AllowanceAmount, SUM(Claims.Amount) as ClaimsTotal, MAX(Allowance.AllowanceAmount) ? SUM(Claims.Amount) as Variance FROM Allowance, Claims WHERE Allowance.AccountID = Claims.AccountID GROUP BY Allowance.AccountID
