Running Balance Trigger Update


With this Trigger :
ON dbo.Transactions
DECLARE @AccBalance money

UPDATE Transactions
      SET balance = (select sum(deposit) - sum(payment) FROM Transactions t2 where t2.TID <= Transactions.TID and t2.AccID = Transactions.AccID and t2.void = 0)
      WHERE Transactions.AccID = i.AccID
      AND Transactions.TID >= i.TID

I'm trying to capture the last 'balance' value updated by the trigger, store it in a local variable, then insert that value in another table.  

I'm not sure how/whether to integrate these require within this trigger or to write another to handle that.  
this is what i need to do.

DECLARE @AccBalance money
INSERT Accounts(Balance, LastUpdated) values (@AccBalance, GETDATE())
WHERE Transactions.AccID = i.AccID

It may be better to simply have a view over the Accounts & Transactions Table.
