Your problem is solved by renaming.

You can either rename your DTML var or your SQL column result name:

DTML var:

  <dtml-let myspam=spam> <!-- you can now access "spam" as "myspam"-->
    <dtml-in sqlstuff>
       ....
       <dtml-if "myspam == spam">....</dtml-if>
       ....
    </dtml-in>
  </dtml-let>

SQL column result name:

  select spam as sqlspam ...

You now access the "spam" column under the name "sqlspam".


I, regularly, use SQL column renaming.
