[Zope-DB] retriving file in a bubble field

[Ufficio Ced]

I have an Oracle database containing word documents in bubble record
I have created a ZSQL method that retrive the document (3 keys are
needed to identify the single document)
If I test the method I can see displayed all the ugly caracters that I
see if I open the document with an ASCII editor.

If I save the content in a file and I open the file it's OK
The matter is: how can I create a link that displays "on the fly" the
document (supposed that the browser is iexplorer and word is
installed)

I have tried enabling direct transverse
http://...../The_sql_method/The_parameter_name/The_value

but I have an oracle error

I'm sorry for the length of the question but Im quite new to Zope and
I still cannot point the problem precisely

Thank you,
Nicola Mersi
