You don't have to do the typechecking in the 'arguments' box if you don't
want. eg. in your arguments section:
And your method:
select * from enrolments
<dtml-sqltest course type=int optional>
<dtml-sqltest subject type=nb optional>
The definition of the 'optional' tag from the docs might help here:
'''A flag indicating if the test is optional. If the test is optional
and no value is provided for a variable, or the value provided is
an invalid empty string, then no text is inserted'''
Hmm... looking at this definition, it seems you have found a bug
(but setting the default value to "" in the arguments section will
provide a workaround). Or maybe 'no value provided' means 'is None'.
Anyone from DC want to provide a ruling? :-)
