从 txt (MS Access 2013) 导入 SQL Server 2016 慢

Question

我的本地 PC 上有一个txt文件，必须对其进行检查，然后使用 ADODB 使用 MS Access 中的存储过程将其逐行上传到 SQL Server 2016。 看起来 Access 总是快速运行 2 行，然后短暂停止。

在 MS Access 中，我使用的是 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 & "', " & _

                     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

在 SQL 服务器上，我有一个如下所示的存储过程：

我必须上传大约 30000 条记录，目前需要一个多小时。

如果您有建议，请告诉我。

Answer 1

对于快速数据传输，请使用启用了批处理操作的断开连接的记录集。

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，这在 2 秒内执行，但它很大程度上取决于 SQL 服务器的位置。

然后，在上传时对数据集进行进一步处理。 基于每条记录的处理通常会很慢。
