Question

我正在尝试使用DAO（在MS-Access中）将记录插入到表中，并且这样做，我收到错误3022（表示违反了唯一索引）。错误是正确的，因为实际上，尝试插入的记录具有已在表中找到的值。

现在，我想找出违反的唯一索引的名称。有人知道我怎么做到这一点？

感谢任何指针勒

以下是一些注释：

Sub WithADO()
''Reference: Microsoft ADO Ext x.x For DLL and Security
Dim catTables As ADOX.Catalog
Dim cn As ADODB.Connection
Dim ndx As Object

Set catTables = CreateObject("ADOX.Catalog")

Set cn = CreateObject("ADODB.Connection")
dbfile = "C:\Docs\LTD.mdb"

    cn.Open "Provider=Microsoft.Jet.OLEDB.4.0;" & _
              "Data Source=" & dbfile & ";"

Set catTables.ActiveConnection = cn

For Each ndx In catTables.Tables("Table1").Indexes
    strlist = ndx.Name & " " & ndx.Properties("Primary Key") & vbCrLf & strlist
Next
MsgBox strlist

Set catTables = Nothing

End Sub

Sub WithDAO()
''Reference: Microsoft DAO x.x Object Library
Dim db As DAO.Database
Dim tdf As TableDef
Dim ndx As Object

Set db = CurrentDb
Set tdf = db.TableDefs("Table1")

For Each ndx In tdf.Indexes

    If ndx.Primary = True Then
        MsgBox ndx.Name
    End If
Next
End Sub

您也可以使用模式。
