通过带查阅列的VBA从Access导入到Excel [英] Import to Excel from Access via VBA with lookup columns

问题描述

我正在将数据从Access表导入Excel。我拥有的导入代码在拉入数据方面起作用，但是当Access表中的列是从另一个表中查找的值时，我对拉入的数据有问题。例如，我将EmployeeID存储在一个单独的表中，该表在我正在提取的表中进行查找。提取提取数据，但它只提取Employee表中分配给Employee表中的Employee的自动编号，而不是员工姓名。员工姓名存储在EMPLOYEE表的第三列中，运行提取时需要该值，而不是自动编号。但是，我不知道如何指定通过VBA在SQL中提取的列。有人能帮帮忙吗？以下是我目前掌握的信息：

Sub getAccessData()

Dim DBFullName As String
Dim Connect As String, Source As String
Dim Connection As ADODB.Connection
Dim Recordset As ADODB.Recordset
Dim Col As Integer
Dim lngLastColumn As Long
Dim lngLastRow As Long
Dim OXLSheet As Worksheet

Set OXLSheet = Worksheets("WorksheetName")

Worksheets("WorksheetName").Cells.Clear

'Datebase path info
DBFullName = "C:UsersmynameDesktopDatabase Backupsdatabase.accdb"

'Open the connection for the database
Set Connection = New ADODB.Connection
Connect = "Provider=Microsoft.ACE.OLEDB.12.0;"
Connect = Connect & "Data Source=" & DBFullName & ";"
Connection.Open ConnectionString:=Connect


'Create RecordSet
Set Recordset = New ADODB.Recordset
With Recordset

    'Data Filter
    Source = "SELECT EmployeeID FROM tblRetirements WHERE AllowEnteredInPayroll]Is Null AND ApplicationCancelled = 'No'"
    .Open Source:=Source, ActiveConnection:=Connection


    'Write field Names
    For Col = 0 To Recordset.Fields.Count - 1
        Worksheets("WorksheetName").Range("A5").Offset(0, Col).Value = Recordset.Fields(Col).Name
    Next

    'Write Recordset
    Worksheets("WorksheetName").Range("A5").Offset(1, 0).CopyFromRecordset Recordset
End With
ActiveSheet.Columns.AutoFit
Set Recordset = Nothing
Connection.Close
Set Connection = Nothing



With OXLSheet
    lngLastColumn = .Cells(5, .Columns.Count).End(xlToLeft).Column
    lngLastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
    .ListObjects.Add(xlSrcRange, .Range(.Cells(5, 1), .Cells(lngLastRow, lngLastColumn)), , xlYes).Name = "Table1"

    ActiveSheet.ListObjects("Table1").TableStyle = "TableStyleMedium16"
End With

End Sub

您在查阅列中看到的实际上是联接的产物，因此要获得名称而不是ID，您需要定义一个推荐答案查询并导出其结果，而不是表本身。要包括主表中的所有记录，您需要使用LEFT JOIN。如果您使用INNER JOIN，则您将获得相同的结果，除非您的主表中存在其Employee表中的相关记录已被删除的记录：

Sub getAccessData()

    Dim DBFullName As String
    Dim Connect As String, Source As String
    Dim Connection As ADODB.Connection
    Dim Recordset As ADODB.Recordset
    Dim Col As Integer
    Dim lngLastColumn As Long
    Dim lngLastRow As Long
    Dim OXLSheet As Worksheet

    Set OXLSheet = Worksheets("WorksheetName")

    Worksheets("WorksheetName").Cells.Clear

    'Datebase path info
    DBFullName = "C:UsersmynameDesktopDatabase Backupsdatabase.accdb"

    'Open the connection for the database
    Set Connection = New ADODB.Connection
    Connect = "Provider=Microsoft.ACE.OLEDB.12.0;"
    Connect = Connect & "Data Source=" & DBFullName & ";"
    Connection.Open ConnectionString:=Connect


    'Create RecordSet
    Set Recordset = New ADODB.Recordset
    With Recordset

        'Data Filter
        Source = "SELECT tblEmployeeID.Name FROM tblRetirements " & _
        "LEFT JOIN tblEmployeeID on tblRetirements.EmployeeID = tblEmployeeID.Name " & _
        "WHERE [AllowEnteredInPayroll] Is Null AND ApplicationCancelled = 'No'"
        .Open Source:=Source, ActiveConnection:=Connection


        'Write field Names
        For Col = 0 To Recordset.Fields.Count - 1
            Worksheets("WorksheetName").Range("A5").Offset(0, Col).Value = Recordset.Fields(Col).Name
        Next

        'Write Recordset
        Worksheets("WorksheetName").Range("A5").Offset(1, 0).CopyFromRecordset Recordset
    End With
    ActiveSheet.Columns.AutoFit
    Set Recordset = Nothing
    Connection.Close
    Set Connection = Nothing



    With OXLSheet
        lngLastColumn = .Cells(5, .Columns.Count).End(xlToLeft).Column
        lngLastRow = .Cells(.Rows.Count, "A").End(xlUp).Row
        .ListObjects.Add(xlSrcRange, .Range(.Cells(5, 1), .Cells(lngLastRow, lngLastColumn)), , xlYes).Name = "Table1"

        ActiveSheet.ListObjects("Table1").TableStyle = "TableStyleMedium16"
    End With

End Sub
