I have a form based on the table below. On the forrm, the filename(all type of documents)
is defined as 'File Browser'. I need to manually insert into the table (instead of using the automated row insert). What is the code needed to insert into the BLOB with SQL?.
Thanks,
Dhanalakshmi.

Then it would seem that there might be something wrong in your branch. Which page are you branching to? Is it a page in your application (which doesn't seem likely) or have you just given in a value in the URL field? Have you checked your table, and is the blob content inserted? (A SQL insert would not be able to throw a HTTP 404 file not found error...)

It is not working ...Agina getting the same error.I think problem starts here.Actually i had tested with some dbms_output statements on step by step process.The error throwing at this point of time.i.e while coming into the below step,
owa_util.mime_header( nvl(v_mime,'application/octet'), FALSE );
throwing error.
Thanks,
Dhanalakshmi.

Oh, I see now that gauravdua's procedure won't even compile. Please test your code before publishing it. (And to both of you, please, the next time publish your code in the actual post, using code tags. It will be a lot easier to read without having to go trough the step of downloading some file. Especially since your code is quite short)
And also, adding a loop around the fetching of the file is of no use. I assume that the id given in is unique, and the error if it wasn't would be too many rows, not numeric or value error. Use the code you originally had. That one will compile at least. And if kb_id is a number you should keep p_file as a number rather than a varchar2. As I said earlier, try granting execute on the procedure to apex_public_user. Call your procedure by using dbsupport.download_my_file?p_file=somefilenumber in the link in your application

Stenerson,
Thanks a lot for your reply...You are absolutely correct..The problem is with Grant to the apex_application_user.Once granted, everything is working fine...
But i couldn't able to understand why we need this grant.Since anyway we are creating the procedure in the same workspace only.Then what is the need of grant.
Please clarify this doubt.
Thanks,
Dhanalakshmi.

Now, this I don't know for sure, but I would assume it's because the function can't be called from your workspace only. E.g. in our company, we have several workspaces residing on the same server. But the applications would all have the same url structure, no matter which workspace they reside in. www.someserver.com/somename/f?p=appnumber.
But when the procedure you defined is called you do it trough www.someserver.com/somename/dbsupport.download_my_file?p_file=somefilenumber
So trough this, which application you are using is not known, and no authentication will be done. By granting access to apex_public_user though, you're letting apex call the procedure regardless of the user. If you want some extra access control you should probably add that to your procedure. (You could just send a HTML document with an error message using htp.p if the person shouldn't have access.) If not, anyone who knows the url will be able to access it.
