Default Excel 2007 VBA ADODB Append Query

Hello All!

So - I have been beating my head against the wall with the following ADODB macro.

Here is what is what I am trying to do, and what is happening:

1) I have a Access 2007 DB sitting on a mapped drive. It is linked to a SharePoint list, and every day it needs to have the data pulled from the list into the "main" storage table in order to be available for other uses - namely for another query to run against the main table - via an append query.

2) The main table has a unique primary key index in it to prevent duplicates. When I run the append query in Access itself I can just click through the warnings, and Access will only insert records that are unique. This works great but I need to be able to help the end users of the spreadsheet be control when that query runs. But I cannot allow them to access the DB directly.

3) So - I created a macro with a ADODB connection that calls this stored query, via an onclick event. It runs - it just will not insert any of the records into to the Access table. At all. Gives me an error that no records were created due to key violations, ect.

Help!!! I will buy you dinner if you can help me figure out a work around that will not entail undoing the primary key (which would create literally THOUSANDS!! of duplicates).

Is there a way to tell Access (via the ADODB connection in Excel) to go ahead and just insert the records that do not violate the primary key - and ignore the ones that do?

Here is the macro:

Sub ADO_AppendQRY_Data()

Dim Cn As ADODB.Connection      ' Connection Object

Dim oCm As ADODB.Command        ' Command Object
Dim CnStr As String             ' Connection String
Dim param As ADODB.Parameter    ' Command Parameter

Dim iRecAffected As Integer

' Dim strSQL As String  ' This will set up the command string

On Error GoTo ADO_ERROR     ' Error Handler

Set Cn = New ADODB.Connection

' Setting up the connection string.  Provider must be Microsoft.ACE.OLEDB.12.0
' Data source string to the S: drive is okay
' Persist Security Info=False (there is no password)

CnStr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=S:mydata_DB.accdb;Persist Security Info=False"

' Connection timeout @ 30 seconds

Cn.ConnectionTimeout = 30

Cn.Open CnStr

Set oCm = New ADODB.Command

oCm.ActiveConnection = Cn

' set the param to run the Append procedure stored in the database

' Set param = New ADODB.Parameter

' With oCm
    oCm.CommandType = adCmdStoredProc
    oCm.CommandText = "appQRY_ImportSP_Data"
    ' .Parameters.Append param
' End With

oCm.Execute iRecAffected

If iRecAffected = 0 Then

MsgBox "No records inserted"

End If

' close connection and set to nothing to free system memory

If Cn.State <> adStateClosed Then

Set Cn = Nothing

End If

Application.StatusBar = False

Set oCm = Nothing
Set param = Nothing
Set rs = Nothing
Set Cn = Nothing

' Error Handler


If Err <> 0 Then

' Debug.Assert Err = 0

MsgBox Err.Description


Resume Next

End If

End Sub
