使用Excel VBA 獲取Access數據庫中表(TableDefs)的字段(Fields)名稱(Name)和類型(Type)

使用DAO和ADODB 2中方法獲取，結果顯示在Debug中，以”,“分開，方便復制到Excel中處理。

附上常用對應關系。

'DAO ADO Type
'1   11  Yes/No
'2   17  Number byte
'3   2   Number Integer
'4   3   Number LongInteger
'4   3   AutoNumber
'5   6   Currency
'6   4   Number Single
'7   5   Number Double
'15  72  Number Replication ID
'20  131 Number Decimal
'8   7   Date/Time
'10  202 Short Text
'11  205 OLE Object
'12  203 Hyperlink
'12  203 Long Text
'16  20  Large Number
'26  135 Date/Time Extended
'101 203 Attachement

程序如下：

Sub GetDatabaseType()
    
    Dim DBE As Object, DB As Object, Tbl As Object, TbName As String
    Dim Rst As Object, SQL As String
    Dim i As Long
    
    TbName = "Hand" '表名
    
    SQL = "SELECT * FROM " & TbName
    Set Rst = CreateObject("ADODB.RecordSet")
    
    Set DBE = CreateObject("DAO.DBEngine.120")
    Set DB = DBE.OpenDatabase(PathBas & "\Database\xxxxx.accdb")'路徑
    Set Tbl = DB.TableDefs(TbName)
    
    Rst.Open SQL, "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & PathBas & "\Database\xxxxx.accdb", 1, 1
    
    With Tbl
        For i = 0 To .Fields.Count - 1
            Debug.Print .Fields(i).Name & "," & .Fields(i).Type & "," & Rst.Fields(i).Type
        Next
    End With

    Rst.Close
    DB.Close
    
    Set Rst = Nothing
    Set Tbl = Nothing
    Set DB = Nothing
    Set DBE = Nothing

End Sub
