Hello,
I have Word documents stored in the Oracle database in the BLOB field
that I need to retrieve. I've found the way of doing it:
While dr.Read
sName = dr("TE_PM_ATTAC H_NAME")
bLob = dr.GetOracleLob (1)
Response.Append Header("Content-type:",
"applicatio n/force-download")
Response.Append Header("Content-Disposition", "attachment ;
filename=" & sName)
Response.Append Header("Content-Length", bLob.Length)
Response.Charse t = "UTF-8"
' write the blob data - this will begin to force the
download
Response.Binary Write(bLob.Valu e)
End While
The only problem here is that when the customer is trying to open the
document, in most cases (but not always, which is weird) he gets
message like this:
This file could not be found.
Try one or more of the following:
* Check the spelling of the name of the document.
* Try a different file name.
(C:\...\Accessi ng BLOB data 2[1].doc)
So he can only download this document.
If it's an image file instead of word document - there are no problems.
I would appreciate any suggestions on how to deal with this.
Thank you,
Peter 11 3933

I think the problem lies here:
Response.Append Header("Content-type:", "applicatio n/force-download")
For word this should be:
"applicatio n/vnd.ms-word"

Thank you very much, Mischa, I'll try this.

Didn't work, unfortunately. It seems to be a problem with the local
caching, but I don't know what exactly.

I'm thinking maybe I should add custom headers in IIS. Not sure what is
required...

Are you giving the downloads distinct filenames ?
If not you might want to try this.
Is this an SSL connection? If so, and you are using IE, if the "Save
Encrypted files to disk" is disabled then IE will not be able to put a copy
of the file in "Temporary Internet Files".

Hi Mischa,
How would I do this? No, I don't. I store the name of the original file
in a separate field, and then just call the row id to retrieve this
file from the BLOB field.

No, this is just our Intranet, no SSL.

Hi Mischa,

in a separate field, and then just call the row id to retrieve this
file from the BLOB field.
You might want to start doing this, otherwise you could use a guid or the id
of the database table:
xxx0123.doc or something. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

Hello,
I've a problem retrieving a blob column from oracle.
I'm using oledbadapter to fill a dataset like that
oledataadap.fill(ds,"query");
I'm also using ColumnMapping to have more friendly column headers in
dataset.
The Fill method send an error with no explaznation except this "the type is
not managed".
Has somebody ideas about to solve that ?

Hi,
I'm trying to select the content from a BLOB field in a oracle table.
The regular select statement doesn't seem to work (Eg. select content
from file_table where file_id=1). It's returning empty content. I'm
using ADODB (http://phplens.com/adodb/) library to execute sql

Could someone please help me out on how to fetch the blob data with
ADODB functions?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
