i am also not sure what you exactly mean, but guessing from the fact
that you have a table with an upload field the code above would work
for that
here is a more complete example

db.define_table('mytable', Field('myfield','upload'))
db.mytable.insert(myfield = db.mytable.myfield.store(open('/etc/
issue'), 'issue file'))
#this is done somewhere in the background when a form is processed so
'issue file' would be the original file name in that case

record = db.mytable[1]
filename, file = db.mytable.myfile.retrieve(record.myfile)
print A(filename, _href = URL(request.application, 'default',
'download', args = record.myfile))

it returns
<a href="/myapplication/default/download/
XXXXSOMESTRANGECODEHERE">issue file</a>

so you have the original file name and the name under which it is
stored? what other original file name would you need?
