>>Now, comes the complication. They have multiple branches or locations each with its own database but they want to merge the databases, hence we'll end up with multiple transactions with the same ID. They do have a location code for each branch so each transaction can be identified by the location code and transaction ID.

and then use OPENXML()? Could you give me a quick example of how to use the XML in the update query?

Something like this:

CREATE procedure [dbo].[uspAssignTransactions] 
	@DepositVoucherID int = null, 
	@xmlDocument xml
as

DECLARE @docHandle int;

EXEC sp_xml_preparedocument @docHandle OUTPUT, @xmlDocument;

UPDATE CaseTransactions
SET DepositVoucherID = @DepositVoucherID
FROM OPENXML(@docHandle, N'/ROOT/Transactions') 

-- here's where I am lost, how to join?
