Import from txt (MS Access 2013) to SQL Server 2016 slow - sql-server

Question

I have a txt file on my local PC, this has to be check and then line by line uploaded into SQL Server 2016 using a Stored Procedure from MS Access using ADODB. It looks like Access is running always 2 rows fast and then making a short stop.
In MS Access I'm using this function:
Public Function ImportData(FileString As String)
Dim WholeLine As String
Dim cc As Variant
Dim sapPurchaseDocument As String
Dim sapPartNumber As String
Dim sapPartName As String
Dim sapDocumentDate As String
Dim sapSupplier As String
Dim sapPlant As String
Dim sapSLoc As String
Dim sapQuantity As Double
Dim sapUOM As String
Dim sapTargetQuantity As Double
Dim sapDeliveryDate As String
Dim sapPrevQuantity As Double
Dim sapReceivedQuantity As Double
Dim sapIssuedQuantity As Double
Dim sapDeliveredQuantity As Double
Dim sapPurchaseRequisition As String
Dim sapPurchaseRequisitionItem As String
Dim sapCreationIndicatior As String
Dim sapNoOfPositions As Double
Dim totalCount As Integer
Dim sapPurchaseDocumentItem As String
Dim rs As New ADODB.Recordset
Call GetConnection
Set rs.ActiveConnection = myCN
If Right(FileString, 3) = "txt" Then
totalCount = GetRowCount(FileString)
Open FileString For Input As #1
i = 0
Do While Not EOF(1)
Line Input #1, WholeLine
If Left(WholeLine, 3) = "| 4" Then
'Debug.Print WholeLine
cc = Split(WholeLine, "|")
sapPurchaseDocument = Trim(cc(1))
sapPartNumber = Trim(Replace(cc(2), ".", ""))
sapPartName = Trim(Replace(cc(3), "'", ""))
sapDocumentDate = Right(cc(4), 4) & "-" & Mid(cc(4), 4, 2) & "-" & Left(cc(4), 2)
sapSupplier = cc(5)
sapPlant = cc(6)
sapSLoc = cc(7)
sapQuantity = Replace(cc(8), ",", "")
sapUOM = Trim(cc(9))
sapTargetQuantity = Replace(cc(10), ",", "")
sapDeliveryDate = Right(cc(11), 4) & "-" & Mid(cc(11), 4, 2) & "-" & Left(cc(11), 2)
sapPrevQuantity = cc(12)
sapReceivedQuantity = Replace(cc(13), ",", "")
sapIssuedQuantity = Replace(cc(14), ",", "")
sapDeliveredQuantity = Replace(cc(15), ",", "")
sapPurchaseRequisition = Trim(cc(16))
sapPurchaseRequisitionItem = Trim(cc(17))
sapCreationIndicatior = cc(18)
sapNoOfPositions = cc(19)
sapPurchaseDocumentItem = Trim(cc(20))
strSQL = "spInsertUpdateSAPME2M '" & sapPurchaseDocument & "', '" & sapPartNumber & "', '" & sapPartName & "', '" & _
sapDocumentDate & "', '" & sapSupplier & "', '" & sapPlant & "', '" & sapSLoc & "', " & _
sapQuantity & ", '" & sapUOM & "', " & sapTargetQuantity & ", '" & sapDeliveryDate & "', " & _
sapPrevQuantity & ", " & sapReceivedQuantity & ", " & sapIssuedQuantity & ", " & _
sapDeliveredQuantity & ", '" & sapPurchaseRequisition & "', '" & sapPurchaseRequisitionItem & "', '" & _
sapCreationIndicatior & "', '" & sapNoOfPositions & "', '" & sapPurchaseDocumentItem & "'"
rs.Open (strSQL)
DoEvents
End If
i = i + 1
Debug.Print i
Forms!frm_Overview.lblStatus.Caption = "Record " & i & " of " & totalCount & " loaded. Please wait!"
DoEvents
'Refresh
Loop
MsgBox "Import done"
End If
Close #1
End Function
And on SQL Server I have a stored procedure which looks like this:
USE [MOBILEPRINT]
GO
/****** Object: StoredProcedure [dbo].[spInsertUpdateSAPME2M] Script Date: 5/25/2020 11:39:31 AM ******/
SET ANSI_NULLS OFF
GO
SET QUOTED_IDENTIFIER ON
GO

I have to upload around 30000 Records which takes more then an hour at the moment.
If you have suggestions, please let me know.

Answer 1

For fast data transfer, use a disconnected recordset with batch operations enabled.
Dim conn As ADODB.Connection
Call GetConnection
Set conn = myCN
Dim rs As New ADODB.Recordset
rs.CursorLocation = adUseClient
rs.Open "Table1", conn, adOpenForwardOnly, adLockBatchOptimistic
'Disconnect
Set rs.ActiveConnection = Nothing
Dim i As Long
For i = 1 To 3000
rs.AddNew
rs.Fields(1) = i
Next
'Reconnect
Set rs.ActiveConnection = conn
'Batch insert
rs.UpdateBatch
Debug.Print Now()
For me, this executes in 2 seconds, but it highly depends on the location of SQL server.
Then, process further on the data set when uploaded. Processing on a per-record basis is usually going to be slow.
