SOLUTION - How to display a BLOB content in Portal Report

Question

Courtesy of Kelly Wong:
1. Every time a record of the file information is inserted into the
PORTAL30.WWDOC_DOCUMENT table while you inserted a record to the blob
field in a portal form that you created.
[The fact that a file uploaded appears in the WWDOC_DOCUMENT table is actually a side-effect of Forms file upload, this may change in a future version. However this example gives a pretty good solution to the problem - Dmitry]
2. If you describe the PORTAL30.WWDOC_DOCUMENT table, you will find
that a few of the columns are: NAME, FILENAME, MIME_TYPE, BLOB_CONTENT,
CREATOR, etc.
3. I created a pl/sql procedure that takes a NAME parameter.
The code of the procedure is as follows:
CREATE OR REPLACE Procedure get_url
(V_FILENAME IN VARCHAR2)
IS
url varchar2(100);
BEGIN
url := '/pls/portal30/docs/'| |v_filename;
portal30.wwv_redirect.url(p_url =>url);
END;
4. I then created a portal report, select NAME, FILENAME, MIMETYPE,
CREATOR fields from PORTAL30.WWDOC_DOCUMENT. (remember, no BLOB_CONTENT
field is selected!) My select statement is:
SELECT '<A
HREF="scott.get_url?v_filename='&#0124; &#0124;name&#0124; &#0124;'">'&#0124; &#0124;filename&#0124; &#0124;'</A>' filename,
name,mime_type,creator
from portal30.wwdoc_document
where creator = 'KELLY'
You can see that I am passing in "NAME" instead of "FILENAME" into the
get_url procedure because the it needs the "NAME" info to display the
file.
Actually, the content in the NAME column is something like:"563.TXT",
and the content in the FILENAME column is "F15675/IPORTAL_LOCAL.TXT".
The hyperlink can be either on the NAME or FILENAME field, as long as
you pass in the content of "NAME" into the procedure.
And it should be fairly easily to substring the FILENAME to show only
"IPORTAL_LOCAL.TXT" if the client doesn't like to see the number
portion.
That is, when I click on the link, I am able to see my file in a new
browser window.The only drawback in this scenario is if there is a link
from your document to a portal component (form/report), it may not link
to the form/report. If there are links in the document link to other
document (html, txt, etc.), it will be no problem. It just open the
document in another browser window.
Please feel free to give me any comment on this and post it to the forum
if needed. I just don't want to search for the original questions in
the forum and attach the reply to it.

Answer 1

Is this method working also for portal 3.0.9?
I can't get it to work.
Is there a way do put a link to download the content of a blob field inside a report in version 3.0.9 that comes with iAS 1.0.2.2?
Thank's in advance
