Using Excel VBA to export data to MS Access table

Question

I am currently using following code to export data from worksheet to MS Access database, the code is looping through each row and insert data to MS Access Table.

Public Sub TransData()

Application.ScreenUpdating = False
Application.EnableAnimations = False
Application.EnableEvents = False
Application.DisplayAlerts = False

ActiveWorkbook.Worksheets("Folio_Data_original").Activate

Call MakeConnection("fdMasterTemp")

For i = 1 To rcount - 1
    rs.AddNew
    rs.Fields("fdName") = Cells(i + 1, 1).Value
    rs.Fields("fdDate") = Cells(i + 1, 2).Value
    rs.Update

Next i

Call CloseConnection

Application.ScreenUpdating = True
Application.EnableAnimations = True
Application.EnableEvents = True
Application.DisplayAlerts = True

End Sub

---

Public Function MakeConnection(TableName As String) As Boolean
'*********Routine to establish connection with database

   Dim DBFullName As String
   Dim cs As String

   DBFullName = Application.ActiveWorkbook.Path & "\FDData.mdb"

   cs = "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & DBFullName & ";"

   Set cn = CreateObject("ADODB.Connection")

   If Not (cn.State = adStateOpen) Then
      cn.Open cs
   End If

   Set rs = CreateObject("ADODB.Recordset")

   If Not (rs.State = adStateOpen) Then
       rs.Open TableName, cn, adOpenKeyset, adLockOptimistic
   End If

End Function

---

Public Function CloseConnection() As Boolean
'*********Routine to close connection with database

On Error Resume Next
   If Not rs Is Nothing Then
       rs.Close
   End If


   If Not cn Is Nothing Then
       cn.Close
   End If
   CloseConnection = True
   Exit Function

End Function

Above code works fine for few hundred lines of records, but apparently it will be more data to export, Like 25000 records, is it possible to export without looping through all records and just one SQL INSERT statement to bulk insert all data to Ms.Access Table in one go?

Any help will be much appreciated.

EDIT: ISSUE RESOLVED

Just for information if anybody seeks for this, I've done a lots of search and found the following code to be work fine for me, and it is real fast due to SQL INSERT, (27648 records in just 3 seconds!!!!):

Public Sub DoTrans()

  Set cn = CreateObject("ADODB.Connection")
  dbPath = Application.ActiveWorkbook.Path & "\FDData.mdb"
  dbWb = Application.ActiveWorkbook.FullName
  dbWs = Application.ActiveSheet.Name
  scn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & dbPath
  dsh = "[" & Application.ActiveSheet.Name & "$]"
  cn.Open scn

  ssql = "INSERT INTO fdFolio ([fdName], [fdOne], [fdTwo]) "
  ssql = ssql & "SELECT * FROM [Excel 8.0;HDR=YES;DATABASE=" & dbWb & "]." & dsh

  cn.Execute ssql

End Sub

Still working to add specific fields name instead of using "Select *", tried various ways to add field names but can't make it work for now.

Solution

is it possible to export without looping through all records

For a range in Excel with a large number of rows you may see some performance improvement if you create an Access.Application object in Excel and then use it to import the Excel data into Access. The code below is in a VBA module in the same Excel document that contains the following test data

Option Explicit

Sub AccImport()
    Dim acc As New Access.Application
    acc.OpenCurrentDatabase "C:\Users\Public\Database1.accdb"
    acc.DoCmd.TransferSpreadsheet _
            TransferType:=acImport, _
            SpreadSheetType:=acSpreadsheetTypeExcel12Xml, _
            TableName:="tblExcelImport", _
            Filename:=Application.ActiveWorkbook.FullName, _
            HasFieldNames:=True, _
            Range:="Folio_Data_original$A1:B10"
    acc.CloseCurrentDatabase
    acc.Quit
    Set acc = Nothing
End Sub
