This is another good idea but its still overkill... :)
I have some queries that return up to 60 fields so its painful to do nvl for
each select that could return a NULL...
Thanks again for the ideas!

Glad that helped, Remy. But changing every dtml-var sounds like overkill. If
the nature of your data truly requires this, an alternative might be to use
Oracle's NVL function. You probably already know about it but, in any case,
it allows you to specify a value with which to replace nulls. E.g., "SELECT
NVL(name,' ') FROM emp;"
