Recordsert not working using the GET method

Question

I'm trying to create a recordset that will retrieve a record from MSSQL.
My recordset is like this:
<%
Dim rsAssets__MMColParam2
rsAssets__MMColParam2 = "1"
If (Request.QueryString("type") <> "") Then
  rsAssets__MMColParam2 = Request.QueryString("type")
End If
%>
<%
Dim rsAssets__MMColParam
rsAssets__MMColParam = "1"
If (Request.QueryString("number") <> "") Then
  rsAssets__MMColParam = Request.QueryString("number")
End If
%>
<%
Dim rsAssets
Dim rsAssets_cmd
Dim rsAssets_numRows
Set rsAssets_cmd = Server.CreateObject ("ADODB.Command")
rsAssets_cmd.ActiveConnection = MM_ezcaldatasource_STRING
rsAssets_cmd.CommandText = "SELECT * FROM dbo.assets WHERE ? = ?"
rsAssets_cmd.Prepared = true
rsAssets_cmd.Parameters.Append rsAssets_cmd.CreateParameter("param1", 200, 1, 255, rsAssets__MMColParam2) ' adVarChar
rsAssets_cmd.Parameters.Append rsAssets_cmd.CreateParameter("param2", 200, 1, 255, rsAssets__MMColParam) ' adVarChar
Set rsAssets = rsAssets_cmd.Execute
rsAssets_numRows = 0
%>
Thi s gives me a Server 500 error...if I just I only use 1 parameter, it works fine. Basically, MMColParam2 is a column in the database (either Asset or Serial) which comes from a field on my form.

try this
Dim rsAssets
Dim  rsAssets_cmd
Dim rsAssets_numRows
Set rsAssets_cmd =  Server.CreateObject ("ADODB.Command")
rsAssets_cmd.ActiveConnection =  MM_ezcaldatasource_STRING
rsAssets_cmd.CommandText = "SELECT * FROM  dbo.assets WHERE '"&request.querystring("type")&"' = '"&request.querystring("number")&"'"
rsAssets_cmd.Prepared = true
im thinking it has to do with either there being a blank value passed... or.. the "content type" is wrong
