Adam, 
I had a similar dilema.  The problem a I saw it was there was a limited amount you could do on the template in terms of server side processing.
I ended up doing this by putting a redirection to an asp page on the template, and getting data from a database using server side scripting.  

In this way I was able to pass a value of the ID for an object selected from the map to that page and do what I wanted with it.  The template code for the 
body is provided blelow, and you do not need to specify a web header, footer or template header in the map file.  In this example, the PadID is replaced by 
mapserver to be the value of C_LINKCODE found for the object in the search, and a second parameter is also passed for query type.

Once on an asp page, you can access databases using standard asp scripting if your on a windows server.  Others may be able to tell you options on unix 
etc. using other scripting languages that can call databases.

Good Luck
Rob

Template code follows.

<!--Start of Page Body-->
<HTML>

<noscript>
<meta http-equiv="refresh" content="1; URL=redirectiontarget.asp">
</noscript>

<BODY>

<SCRIPT LANGUAGE="JavaScript">

<!-- Begin
window.location="/queries/QueryDisplay.asp?PadId=[C_LINKCODE]&QType=Harvest";
// End -->
</script>

</HTML>
