Question

我正在尝试下面的LDAP查询。 “描述”字段通常为空，但如果存在数据，则会在RS.Fields（vFields（iCol））上出现类型不匹配错误。描述列的值。 ADO数据类型报告为12 - Variant。我试图将值赋给VBA Variant，但它没有用。

请原谅写入文件的无关行。如果您尝试重现，则需要参考Microsoft ADO 6。也改为你的OU

如何在VBA中使用ADP数据类型12？我可以修改SELECT语句以隐藏描述另一种数据类型吗？

             If Not IsNull(RS.Fields(vFields(iCol))) Then
                vData = RS.Fields(vFields(iCol)) ' vData is declared as a Variant
                wks.Cells(iRow, iCol) = vData(0) & "" ' only captures first array element

请参阅下面的文字，它会将您排除在外。这是从here

应该指出的是＆＃34;描述＆＃34;用户对象的属性实际上是多值的。但是，它只能有一个值。它被ADSI视为普通字符串，但不是ADO。 ADO返回Null（如果＆＃34;描述＆＃34;属性没有值）或一个字符串值的数组。您必须为此属性使用类似于BELOW的代码。

大多数Active Directory属性都具有字符串值，因此您可以直接回显值，或将值分配给变量。某些Active Directory属性不是单值字符串。 ADO将多值属性作为数组返回。示例包括属性memberOf，directReports，otherHomePhone和objectClass。在这些情况下，如果多值属性中没有值，则Fields集合的Value属性将为Null，如果有一个或多个值，则将为数组。例如，如果属性列表包含sAMAccountName和memberOf属性，则可以使用类似于以下的循环枚举Recordset对象：

Do Until adoRecordset.EOF
    strName = adoRecordset.Fields("sAMAccountName").Value
    Wscript.Echo "User: " & strName
    arrGroups = adoRecordset.Fields("memberOf").Value
    If IsNull(arrGroups) Then
        Wscript.Echo "-- No group memberships"
    Else
        For Each strGroup In arrGroups
            Wscript.Echo "-- Member of group: " & strGroup
        Next
    End If
    adoRecordset.MoveNext
Loop

使用ADO
