用 压缩并修复数据库 調試過後後，可以更新了，再第二次再更新之後，問題又來了，還是老樣的問題，有請各位大虾指點指點！

数据库的索引是用 （有重复）

<%
If (CStr(Request("MM_update")) = "form1") Then
  If (Not MM_abortEdit) Then
    ' execute the update
    Dim MM_editCmd

    Set MM_editCmd = Server.CreateObject (")
    MM_editCmd.ActiveConnection = MM_connms_STRING
    MM_ = "UPDATE MS_productspdf SET mctl_id = ?, ctl_id = ?, cp_id = ?, p_name = ?, p_nameeng = ? WHERE pdf_id = ?"
    MM_editCmd.Prepared = true
    MM_editCmd.Parameters.Append MM_editCmd.CreateParameter("param1", 5, 1, -1, MM_IIF(Request.Form("s1"), Request.Form("s1"), null)) ' adDouble
    MM_editCmd.Parameters.Append MM_editCmd.CreateParameter("param2", 5, 1, -1, MM_IIF(Request.Form("s2"), Request.Form("s2"), null)) ' adDouble

    MM_editCmd.Parameters.Append MM_editCmd.CreateParameter("param6", 5, 1, -1, MM_IIF(Request.Form("MM_recordId"), Request.Form("MM_recordId"), null)) ' adDouble
    MM_editCmd.Execute     '这里是40行
    MM_editCmd.ActiveConnection.Close

    ' append the query string to the redirect URL
    Dim MM_editRedirectUrl
    MM_editRedirectUrl = "in_zpdf.asp"
    If (Request.QueryString <> "") Then
      If (InStr(1, MM_editRedirectUrl, "?", vbTextCompare) = 0) Then
        MM_editRedirectUrl = MM_editRedirectUrl & "?" & Request.QueryString
      Else

是使用Dreamweaver MX自动生成的代码

有没有人曾经遇到过这种情况呀，帮帮忙呀~~~

有主键的呀~~~~问题至今仍没解决，有请高手指点！！

不会吧，有谁知道能解决这样的问题吗？

但是这种方法不是根治这个故障的主要方法。只要你第二次还有提交一个大块数据给这个备注型字段，这个故障又出来啦！！
