Question

我正在探索使用SQL Server 2008进行全文索引搜索并遇到两组错误。

它源于我用VBScript调用的存储过程，它生成会生成搜索命中列表记录集。存储过程在SQL Server Management studio中运行良好，基本上生成搜索命中列表。参数是关键字和突出显示的样式。

最初的错误：

错误一： ADODB.Recordset错误'800a0e78关闭对象时不允许操作

在ASP代码的If not recordset.EOF行。然后，一些读取和搜索指向SET NOCOUNT ON;，尤其是在引用临时表（KB235340）时。

但是当我指定SET NOCOUNT ON时，我收到“错误二”中列出的错误。关于权限的NB我已经为运行存储过程的帐户分配了EXECUTE权限，以突出显示搜索命中。

错误二： Microsoft OLE DB Provider for SQL Serve错误'80040e14' 用户无权执行此操作

添加SET NOCOUNT ON时出现错误二。

ASP代码：突出显示导致错误的行

    Dim cmd
    Dim newParameter
    Dim recordset
    Dim SearchTerm
    Dim Style

    SearchTerm = ""
    SearchTerm = Request("searchTerm")
    Style = "background-color:yellow; font-weight:bold"

    Dim objConnectionMICenter
    Set objConnectionMICenter = Server.CreateObject("ADODB.Connection") 
    objConnectionMICenter.Open Session("ConnectMICenter") 

    Set cmd  = Server.CreateObject("ADODB.Command")
    Set cmd.ActiveConnection = objConnectionMICenter

   ' Define the stored procedure's inputs and outputs
   ' Question marks act as placeholders for each parameter for the
   ' stored procedure
   cmd.CommandType = 4 ' adCmdStoredProc
   cmd.CommandText = "HelpAndCalculationNoteHighlight"

    '--- Create and append parameter for SearchTerm 
    Set newParameter = cmd.CreateParameter("SearchTerm",203 ,1,100,SearchTerm)
    cmd.Parameters.Append newParameter

    '--- Create and append parameter for SearchTerm 
    Set newParameter = cmd.CreateParameter("Style",203 ,1,200,Style)
    cmd.Parameters.Append newParameter

    Set recordset = cmd.Execute()

     **If not recordset.EOF Then**
        While Not recordset.EOF
            response.Write "<div>" & recordset.Fields("Snippet") & "</div>"
            recordset.MoveNext
        Wend
    end if

    Response.Write strPreviewContents

    Set objConnectionMICenter = Nothing
    Set newParameter = Nothing
    Set cmd = Nothing

    recordset.Close
    Set recordset = Nothing

存储过程：

Answer 1

您使用的sys.dm视图需要提升权限

sys.dm_fts_parser = sysadmin
sys.dm_fts_index_keywords_by_document =创建FULLTEXT目录

正如您所提到的，您使用的是两套不同的凭据。

您是SSMS中的sysadmin和vb脚本中的普通用户。

您可以在存储过程中尝试“EXECUTE AS OWNER”。或者尝试在master中的视图中包装sys.dm_fts_parser（同时使用EXECUTE AS OWNER）

ADODB.Recordset错误'800a0e78对象关闭时不允许操作：对临时表存储过程需要SET NOCOUNT ON
