I'm trying to do something in a DTML-Method (in ancient Zope 2.6.2)
that seems like it should be really simple, but I can't get it right.
I want to see if a value (defined via url-arg) is in a list which is
generated from an RDBMS query (field type=integer).
The pseudo-code would be something
if foo in (select foo_col from table where x=y)
then z='t'
else z='f'
I tried putting the simple SELECT query into a zSql and then calling it
like:
dtml-call REQUEST.set('foo_list',IfShowNextDoor())
dtml-if expr=foo in foo_list
dtml-call REQUEST.set('z','t')
dtml-else
