Hope that helps, Bill Grant Hi, thanks for all the info: The VB Code is the following: ' mod Copy Tables: Module ' ' Functions for storing data in SQL Tables ' ' Project: ' CR100860 Telephone Data Warehouse ' Author: ' Matt Hayes ' SOUTHAMPTON February 2004 ' Current Version: ' V0.0.1 ' ' Objects affected: ' SQL Server Data repository ' ' Version history: ' 2004-02-29 0.0.1 MH Created ' 2004-05-07 0.0.2 MH Updated Error Trapping ' Option Explicit ' Copytable: Void ' ' Copies tables ' ' Input: ' str Source Table: String name of source table ' str Source DSN: String source connection string ' str SQL_Where: String SQL Where clause used when selecting source data ' str Dest Tbl: String name of destination table ' str Dest DSN: String destination connection string ' int Source Tbl ID: Integer source table unique identifier ' dbl Update Per: Double table update period in hours ' dte Last Updated: Date date table was last updated ' int Perf Log Level: Integer performance logging level (1,2,3) ' Outputs: ' NONE ' Returns ' N/A ' Public Function Copy Table( _ str Source Tbl As String, _ str Source DSN As String, _ str SQL_Where As String, _ str Dest Tbl As String, _ str Dest DSN As String, _ int Source Tbl ID As Integer, _ dbl Update Per As Double, _ int Perf Log Level As Integer, _ dte Last Updated As Date, _ str Custom1 As String, _ gint Tbls Written As Integer) As Boolean Dim str Source SQL As String Dim str Rec Count SQL As String Dim intx As Integer Dim int Err Count As Integer Dim dbl Rec Count As Double Dim lng Data Size As Long Dim lng Defined Size As Long Dim int Recs Skipped As Integer Dim int Recs Written As Integer On Error Go To ERR_PROC Set gconn Source = New ADODB. In either event, you could strip down the VB program to just make the call (UPDATE or EXEC PROC), not have to worry about concurrency, and get a very nice speed improvement at the same time. Bill I know what you mean, If it was up to me I would do the whole thing in DTS! DTS is kind of another external program not unlike VB.

How would you logically go about coding an UPDATE/INSERT statement in VB? It does not run in the context of the database and it is record based instead of set based so you have much more overhead than you do with a stored procedure.
