my assumption that once a dataset is created and tables loaded I assume another datatable referencing tables within the dataset is only going to increase resource usage minimally

is it possible

FOR INSERT
AS

declare @IDVal as int
declare @nCount as int

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE

You should be able to put your MID functions in the JOIN clause:

SELECT
[DATE] as tblS_Date,
MID([2ND REFERENCE_],1,9) as tblS_CellNr,
MID([Cell Number],2,9) as tblB_CellNr,
[Total___] as tblB_Total
FROM
Statement as tblS
INNER JOIN
Billing as tblB
ON MID(tblS.[2ND REFERENCE_],1,9) = MID(tblB.[Cell Number],2,9)

How would the select/join statement look like

SELECT tblEmployees.*, tblLoanAmount.*
FROM [C:\costToCompany.mdb].tblEmployees 
LEFT JOIN [C:\Accounts.mdb].tblLoanAmount ON tblEmployees.EmployeeID = tblLoanAmount.EmployeeID
