[Zope] Render SQL method as lines

[Kenneth Ellested]

How do I render a SQL method as lines ?

I'd like to make a DB lookup for a Multi-Selection property.

This is my DTML method (getNames is a SQL method):
<dtml-in getNames>
<dtml-var name>
</dtml-in>

But this renders as a string which is not compatible...
