Ok. I got the general idea. Thanks Vincent. My next question is: How do I convert the bytea content stored in Postgresql into the real file so I can put it in a local directory? (and the opposite process: store a file on a path to a postgresql database) I know this could be more an access issue but I'm quite newbie...

I do this from a navigator now, but the general idea is : use this table structure: create table ( id_document serial, content bytea, extension text) In your form, display a list of links, one for each file, pointing to a directory you can write to, with the file's id and extension. So if file id is 7001, extension is pdf, path is : your/directory/7001.doc Write the file's data to disk, obviously using the same name for the file as in the link, once the user clicks on the link, using the on_click event : file will be served to the user. -- Salutations, Vincent Veyron http://marica.fr/site/demonstration Progiciel de gestion des sinistres assurance et des dossiers contentieux pour le service juridique -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
