I am adding a page using .asp and dreamweaver cs6.  the first page loads information and the second page will be a photo upload page, but must know the identity of the record just inserted.  I used to have an extension that did this (Tom Mucks) that would load the Id into a session variable.  That extension doesn't work now in Dreamweaver CS6.  I'm looking for the best way to do this.  I know its with @@identity, but not really sure how to use it?

it depends to what you need:

there are several options
SCOPE_IDENTITY, IDENT_CURRENT, and @@IDENTITY are similar functions in that they return values inserted into IDENTITY columns.

IDENT_CURRENT is not limited by scope and session; it is limited to a specified table. IDENT_CURRENT returns the value generated for a specific table in any session and any scope. For more information, see IDENT_CURRENT.

SCOPE_IDENTITY and @@IDENTITY will return last identity values generated in any table in the current session. However, SCOPE_IDENTITY returns values inserted only within the current scope; @@IDENTITY is not limited to a specific scope.


try to use
SCOPE_IDENTITY
more with code examples (@@identity as well)

hi

select scope_identity() -- your specific sessions insert

select @@identity -- the last identity used

Ok I have two pages.

1st page adds basic info
2nd page adds photo

Do I use the scope_identity() on the first page and put into session variable?  Or do I put it on the second page in the SQL statement?

First page and pass it to the second page using either a session variable or some other mechanism.

ok I think I can pass it to the second page with a session variable, but not sure how to implement it into the default dreamweaver code.  I didn't used to have a problem, but then they rewrote they way they handle querys etc due to SQL injection attacks.  Here is just a blank page that inserts into one column:

<%@LANGUAGE="VBSCRIPT" CODEPAGE="65001"%>
<!--#include file="Connections/durgorama.asp" -->
<%
Dim MM_editAction
MM_editAction = CStr(Request.ServerVariables("SCRIPT_NAME"))
If (Request.QueryString <> "") Then
  MM_editAction = MM_editAction & "?" & Server.HTMLEncode(Request.QueryString)
End If

' boolean to abort record edit
Dim MM_abortEdit
MM_abortEdit = false
%>
<%
If (CStr(Request("MM_insert")) = "form1") Then
  If (Not MM_abortEdit) Then
    ' execute the insert
    Dim MM_editCmd

    Set MM_editCmd = Server.CreateObject ("ADODB.Command")
    MM_editCmd.ActiveConnection = MM_durgorama_STRING
    MM_editCmd.CommandText = "INSERT INTO dbo.baubscope (scopebaub) VALUES (?)" 
    MM_editCmd.Prepared = true
    MM_editCmd.Parameters.Append MM_editCmd.CreateParameter("param1", 202, 1, 50, Request.Form("scopebaub")) ' adVarWChar
    MM_editCmd.Execute
    MM_editCmd.ActiveConnection.Close

    ' append the query string to the redirect URL
    Dim MM_editRedirectUrl
    MM_editRedirectUrl = "scopetest2.asp"
    If (Request.QueryString <> "") Then
      If (InStr(1, MM_editRedirectUrl, "?", vbTextCompare) = 0) Then
        MM_editRedirectUrl = MM_editRedirectUrl & "?" & Request.QueryString
      Else
        MM_editRedirectUrl = MM_editRedirectUrl & "&" & Request.QueryString
      End If
    End If
    Response.Redirect(MM_editRedirectUrl)
  End If
End If
%>

Dim baubscope
Dim baubscope_cmd
Dim baubscope_numRows

Set baubscope_cmd = Server.CreateObject ("ADODB.Command")
baubscope_cmd.ActiveConnection = MM_durgorama_STRING
baubscope_cmd.CommandText = "SELECT * FROM dbo.baubscope" 
baubscope_cmd.Prepared = true

Set baubscope = baubscope_cmd.Execute
baubscope_numRows = 0
