我有这三个表 [ Orders, order_Items, order_comment ]

|    -Orders-    |     |  -Order_Items-   |     | -Order_comment- |
|    order_id    |     |  order_RegCode   |     |    order_id     |
| order_RegCode  |

如您所见，这三个表通过 2 个唯一键关联在一起！order_id和order_RegCode。

ps：order_RegCode不是主键，是字符串！

我想当我删除任何订单时order_id，删除存储在另外两个表中的所有相关信息。但是当我使用 Do While 我得到error Operation is not allowed when the object is closed.

请指导我。

该代码是：

Dim Order_ID
    Order_ID = Int(Request.Form("ID"))

Set Conn = server.createobject("adodb.connection")
Conn.open StrConn
Set Rs = Conn.execute("SELECT * From orders WHERE order_id="& Order_ID &"")
If NOT Rs.EOF then

    RegCode = Rs("order_RegCode")

    '//== Delete Order
    Set Rs = Conn.execute("Delete From orders where order_id = "& orderID &"")

    '//== Delete All Comments Belong to Order
    Set Rs = Conn.execute("Select * From order_comment where order_id = "& Order_ID &"")
    If NOT Rs.EOF then
        Do While NOT Rs.EOF
            Set Rs = Conn.execute("Delete From order_comment where order_id = "& Order_ID &"")
        Rs.MoveNext
        Loop
    End if

    '//== Delete All Items Belong to Order
    Set Rs = Conn.execute("Select * From order_items where order_code = '"& RegCode &"'")
    If NOT Rs.EOF then
        Do While NOT Rs.EOF
            Set Rs = Conn.execute("Delete From order_items where order_code = '"& RegCode &"'")
        Rs.MoveNext
        Loop
    End if

End if

您不得将记录集用于操作查询。这些行：

Set Rs = Conn.execute("Delete ...

应该：

Conn.execute("Delete ...

您不能对所有记录集使用相同的对象。您将需要一个记录集用于外部循环，另一个用于内部循环。不过，我建议：

Dim Order_ID
Order_ID = Int(Request.Form("ID"))

Set Conn = server.CreateObject("adodb.connection")
Conn.Open StrConn
Set rs = Conn.Execute("SELECT * From orders WHERE order_id=" & Order_ID)
If Not rs.EOF Then

    RegCode = rs("order_RegCode")

    '//== Delete Order
    Conn.Execute ("Delete From orders where order_id = " & orderID)
    Conn.Execute ("Delete From order_comment where order_id = " & Order_ID)
    Conn.Execute ("Delete From order_items where order_code = '" & RegCode & "'")

End If
