Jim; This depends on how you are binding the variable. For example,
using an OPTIONAL clause in IterateOverSelect will bind the variable
for each iteration. For example:
SELECT ?s ?label
WHERE
{ ?s a :Thing .
OPTIONAL {?s rdfs:label ?label .}.
}
...the ?label will be bound to a value if bound for that result and
unbound otherwise.
