Question

I’m exploring full text index searching using SQL Server 2008 and encounter two sets of errors.

It stems from a a stored procedure I call with VBScript which generates would generate search hit list recordset. The stored procedure runs fine in SQL Server Management studio and basically generates a search hit list. Arguments are keyword, and style for highlighting.

Initially error:

Error One: ADODB.Recordset error ‘800a0e78 Operation is not allowed when the object is closed

at the If not recordset.EOF line in the to ASP code. Then a bit of reading and searching pointed having SET NOCOUNT ON; especially when referencing temporary tables (KB235340).

However when I specify SET NOCOUNT ON I get the error listed in “error two”. NB regarding permissions I have EXECUTE permission assigned to the account running the stored procedure to highlight the search hits.

Error Two: Microsoft OLE DB Provider for SQL Serve error ‘80040e14’
The user does not have permission to perform this action

Error Two occurs when add the SET NOCOUNT ON.

ASP Code: Line causing the error is highlighted

    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

Answer 1

The sys.dm views you use require elevated permissions

• sys.dm_fts_parser = sysadmin
• sys.dm_fts_index_keywords_by_document = CREATE FULLTEXT CATALOG

As you mentioned, you are using 2 different sets of credentials.

You are sysadmin in SSMS and plain user from vb script.

You can try “EXECUTE AS OWNER” in the stored procedure. Or try wrapping sys.dm_fts_parser in a view in master (also with EXECUTE AS OWNER)
