我在本地PC上有一个txt文件，必须对此进行检查，然后使用ADODB从MS Access使用存储过程逐行将其上载到SQL Server 2016。看起来Access总是总是快速运行2行，然后稍作停顿。
在MS Access中，我正在使用此功能：
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 & "', " & _

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
并且在SQL Server上，我有一个如下所示的存储过程：

我必须上传大约30000条记录，此刻需要花费一个多小时的时间。
如果有建议，请告诉我。
为了快速进行数据传输，请使用已启用批处理操作的断开记录集。
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()
对我来说，这将在2秒内执行，但这在很大程度上取决于SQL Server的位置。
然后，上传后对数据集进行进一步处理。按记录的处理通常会很慢。
