I am recieving a CLOB from an oracle query.
How should my .CreateParameter method's parameters look?

This is what I have , but the app seems to be bombing out

.Parameters.Append .CreateParameter("highlight", adVarChar, adParamInput, 57478)

I believe that an adVarChar needs a length parameter and that a text value needs delimiters:

.Parameters.Append .CreateParameter("highlight", adVarChar, adParamInput, 5, "57478")

I dont think this way works at all for a CLOB. Im trying to find a way to make it work.

Well, I don't know about CLOBS, but if you are using an adVarChar, .CreateParameter will require all of those parameters.

A few things to check:

Still Havent figured it out im calling a stored procedure last and thats whats blowing up my code. The first 3 createParameters have been tested and work.
The 4th CreateParameter is recieving a CLOB and thats what is messing me up.

    sql = "SELECT doc_id, display_name, " &_
           "to_char((SELECT MAX(process_end_time) FROM CONVERT_LOG l WHERE l.doc_id=d.doc_id), 'MM/DD/YYYY HH:Mi:SS PM')  publish_date" &_
        "Markup_First_Hit(d.doc_id, 'dog', '<b><font style=""background:#FFFF99"">', '</B></font>') highlight " &_
        "FROM DOCUMENTS d WHERE published=1"

      Set oCmd = Server.CreateObject("ADODB.COMMAND")
            With oCmd
            .ActiveConnection = conn
            .CommandType = adCmdText
            .CommandText = sql
            .Parameters.Append .CreateParameter("doc_id", adInteger)
            .Parameters.Append .CreateParameter("display_name", adVarChar)
            .Parameters.Append .CreateParameter("publish_date", adVarChar)
            .Parameters.Append .CreateParameter("highlight")
      end with
      
      Set rst = oCmd.Execute
      Set oCmd = Nothing

I am okay with the refund as long as bertino posts his final solution so that others might reference it.

I didnt change anything, but took off the createParameter. The select statement contained a stored procedure, but wasnt a stand alone stored procedure so there was no need for createParameter functions.

Just post your solution, as your explanation makes no sense.

How does removing the createParameter not make sense?

   sql = "SELECT doc_id, display_name, " &_
          "to_char((SELECT MAX(process_end_time) FROM CONVERT_LOG l WHERE l.doc_id=d.doc_id), 'MM/DD/YYYY HH:Mi:SS PM')  publish_date" &_
       "Markup_First_Hit(d.doc_id, 'dog', '<b><font style=""background:#FFFF99"">', '</B></font>') highlight " &_
       "FROM DOCUMENTS d WHERE published=1"

     Set oCmd = Server.CreateObject("ADODB.COMMAND")
          With oCmd
          .ActiveConnection = conn
          .CommandType = adCmdText
          .CommandText = sql
     end with
     
     Set rst = oCmd.Execute
     Set oCmd = Nothing

>>How does removing the createParameter not make sense?<<
I was not referring to that, but rather this:
"The select statement contained a stored procedure, but wasnt a stand alone stored procedure so there was no need for createParameter functions."

A select statement cannot contain a stored procedure,, perhaps you meant the reverse: the stored procedure contained a select statement.

I have no idea what you meant by "stand alone stored procedure", perhaps you mean/meant one that does not have parameters.

But the bottom line is that your code does not contain any stored procedures.  Period.  Further you do not even need a Command object for such a trivial exercise.

Glad you got it figured out.
