I have three tables..
1) Accounts
2) Orders
3) OrdersProcessed

I need to come up with all the Orders records that have a matching Accounts record (based on AccountNumber) but do not have a matching OrdersProcessed record (based on OrderID and AccountNumber) and AccountNumber is like 'B%'. I tried the following query and it's not returning what I expect, it returns all the rows from Orders even though they have a matching record in the OrdersProcessed table. Any ideas?

SELECT O.AccountNumber, O.OrderID, O.Quantity, O.BuySell
FROM PFX_Orders O
FULL OUTER JOIN PFX_OrdersProcessed P ON O.AccountNumber = P.AccountNumber
AND O.OrderID = B.OrderID
INNER JOIN PFX_Accounts A ON A.AccountNumber = O.AccountNumber
WHERE O.AccountNumber like 'B%'

[code]
SELECT
O.AccountNumber,
O.OrderID,
O.Quantity,
O.BuySell
From PFX_Orders O
Inner Join PFX_Accounts A
On A.AccountNumber = O.AccountNumber
Left JOIN PFX_OrdersProcessed P
On O.AccountNumber = P.AccountNumber
and O.OrderID = B.OrderID
WHERE O.AccountNumber like 'B%'
and P.AccountNumber is null
[/code]
