Dowload blobs from Database

Question

I know this is not the best way to store files but I have inherited an old php script which I am converting to CF because php is useless.
Now i have a script to do this in php but can this be achived with CF? It is just a quick fix until I have time to rework the CMS
<?php
if(isset($_GET['id']))
// if id is set then get the file with the id from database
$id    = $_GET['id'];
$query = "SELECT name, type, size, content " .
         "FROM upload WHERE id = '$id'";
$result = mysql_query($query) or die('Error, query failed');
list($name, $type, $size, $content) =                                  mysql_fetch_array($result);
header("Content-length: $size");
header("Content-type: $type");
header("Content-Disposition: attachment; filename=$name");
echo $content;
i
exit;
?>

My php experience is NILL, but applying basic coding experience I believe your CFML will be close to this.
<cfif structKeyExists(url,"id")>
  <cfquery datasource="..." name="result">
    SELECT name,type,size,content
    FROM upload
    WHERE id = <cfqueryparam value="#url.id#" cfsqltype="cf_sql_integer">
  </cfquery>
  <cfheader name="Content-Disposition: atachment; filename=#result.name#">
  <cfcontent type="#result.type#" reset="yes">
  #result.content#
</cfif>
If any of this content can be binary, then you may also need to use one or more of the toBinary() toBase64(), isBinary(), binaryDecode() or other relevant functions.
