使用Excel VBA将数据导出到MS Access表

时间:2022-04-17 23:50:18

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.

我目前正在使用以下代码将数据从工作表导出到MS Access数据库,代码循环遍历每一行并将数据插入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?

上面的代码适用于几百行记录,但显然它将导出更多数据,如25000条记录,是否可以在不循环遍历所有记录的情况下导出,只需一个SQL INSERT语句即可将所有数据批量插入到Ms.Access表一气呵成?

Any help will be much appreciated.

任何帮助都感激不尽。

EDIT: ISSUE RESOLVED

编辑:问题已解决

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!!!!):

只是为了获取信息,如果有人寻求这个,我已经做了很多搜索,并发现以下代码对我来说工作正常,并且由于SQL INSERT,它是真正的快速,(仅在3秒内27648条记录! ):

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.

仍在努力添加特定字段名称而不是使用“Select *”,尝试了各种方法来添加字段名称,但现在无法使其工作。

is it possible to export without looping through all records

是否可以导出而不循环遍历所有记录

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

对于具有大量行的Excel中的范围,如果在Excel中创建Access.Application对象,然后使用它将Excel数据导入Access,则可能会看到一些性能改进。下面的代码位于包含以下测试数据的同一Excel文档中的VBA模块中

Option Explicit

Sub AccImport()
    Dim acc As New Access.Application
    acc.OpenCurrentDatabase "C:\Users\Public\Database1.accdb"
    acc.DoCmd.TransferSpreadsheet _
            TransferType:=acImport, _

    acc.CloseCurrentDatabase
    acc.Quit
    Set acc = Nothing

Below is code that specifies fields from a named range for insertion into MS Access. The nice thing about this code is that you can name your fields in Excel whatever the hell you want (If you use * then the fields have to match exactly between Excel and Access) as you can see I have named an Excel column "Haha" even though the Access column is called "dte".

下面是代码,用于指定插入MS Access的命名范围中的字段。关于这段代码的好处是,无论你想要什么,你都可以在Excel中命名你的字段(如果你使用*那么字段必须在Excel和Access之间完全匹配),你可以看到我已经命名了一个Excel列“Haha”即使Access列被称为“dte”。

Sub test()
    dbWb = Application.ActiveWorkbook.FullName
    dsh = "[" & Application.ActiveSheet.Name & "$]" & "Data2"  'Data2 is a named range


sdbpath = "C:\Users\myname\Desktop\Database2.mdb"
sCommand = "INSERT INTO [main] ([dte], [test1], [values], [values2]) SELECT [haha],[test1],[values],[values2] FROM [Excel 8.0;HDR=YES;DATABASE=" & dbWb & "]." & dsh

Dim dbCon As New ADODB.Connection
Dim dbCommand As New ADODB.Command

dbCon.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & sdbpath & "; Jet OLEDB:Database Password=;"
dbCommand.ActiveConnection = dbCon

dbCommand.CommandText = sCommand
dbCommand.Execute

dbCon.Close


End Sub
