Data upload and download

Hi,
I have a query in using open dataset command.
let us consider this scenario as an example.
I need to select 5 fields from mara table and I want to display the output in a flat file.Later, I have to read the data from the flat file and to display the output in sap screen.
Can someone help me on doing this and also if you send me the code , it will be useful for me to understand.
Thanks,
Stal.

DATA: BEGIN OF T_MARA OCCURS 0,
MATNR TYPE MARA-MATNR,
END OF ITAB.
DATA : BEGIN OF T_MARA OCCURS 0,
LINE(75)TYPE C,
END OF ITAB.
SELECT MATNR FROM MARA INTO TABLE T_MARA .
OPEN DATA SET W_FILE_NAME FOR OUT PUT IN TEXT MODE ENCODING DEFAULT.
LOOP AT T_MARA.
TRANSFER T_MARA.
ENDLOOP.
CLOSE DATA SET.
NOW ALL THE DATA IS TRANSFERD TO APPP SERVER.
NOW IF U WANT TO READ....
OPEN DATASET W_FILENAME FOR INPUT IN TEXT MODE ENCODING DEFAULT.
IF SY-SUBRC NE 0.
MESSAGE E000 WITH 'FILE NOT FOUND'.
ELSE.
DO .
READ DATA SET W_FILE NAME INTO T_ITAB2.
IF SY-SUBRC NE 0.
EXIT .
ENDIF.
END DO.
CLOSE DATA SET.
*********NOW ALL THE DATA IS PRESENT IN T_ITAB2.
LOOP AT T_ITAB2.
*******SUPOOSE IF U R HAVING MORE FIELDS MEANS ***USE SPLIT.
SPLIT AT ',' T_ITAB2 INTO T_MARA-MATNR.
APPEND T_MARA.
ENDLOOP.

How to upload and download in BLOB?

I tried webutil but is not working properly according to my needs is there any other way to upload and download files in BLOB?
If any body knows solution please tell me.
Regards,

Dear Colleague,
In my Forms application, I use the WEBUTIL to load files into a BLOB column. However, prior to getting WEBUTIL to work, I loaded files into the BLOB column using the following PL/SQL code.
Note, that the example assumes that the row already exists in the table and you are updating it by loading the file into the BLOB. You will also be required to first create a Database Directory object (in my case, it was called "RKMS_DOC_DIR")
I do not have an example for downloading, as I use the WEBUTIL functionality for this.
Good luck!

Hi,
Well,i don't know whether if this helps people here are not.
It is always a good practise to do it via Servlet and then download content.
The adavantage of doing this is
1). You may not need to pack the downloadable with the .war which you ultimately genrate which ceratinly help us in terms of faster deployment.
3). You may update the new content just by moving a file to the backup folder.
2).One may definately download the content irrespective to the content/file.
Hope example below helps..
Configurations:
In the above example we are assuming that we placing all downlodable file in D:/webapp/downlodables/ and you have configured the same path as a init param with the name "filePath" in your web.xml.
something like the one below.
<servlet>
    <servlet-name>DownloadServlet</servlet-name>
    <servlet-class>com.DownloadServlet</servlet-class>
    <init-param>
       <param-name>filePath</param-name>
       <param-value>D:/webapp/downlodables/</param-name>
       
    </init-param>
</servlet>
<servlet-mapping>
    <servlet-name>DownloadServlet</servlet-name>
    <url-pattern>/downloadFile</url-pattern>

File Upload and Download in Oracle iAS PL/SQL Gateway

i'm using the example 113471.1 to "File Upload and Download in
Oracle iAS PL/SQL Gateway"
when i press the submit button after i select a file to upload
i get the next message in the browser "No se puede mostrar la
pagina" HTTP 404 file not found.
I think the problem is in ctnsample.upload_form in the line
htp.formOpen(curl => 'cntsample.upload', cmethod => 'POST',
cenctype => 'multipart/form-data');
The ctnsample.remove work fine.
Could you,help me...

There is a document in the Oracle 9iAS 1.0.2.2 Library titled "Using the PL-SQL Gateway" Part Number A90099-01.pdf that explains file upload and download through modplsql. In particular there is a section there titled "Direct BLOB Download" which explains how one can easily download a blob utilising the wpg_docload package.
I am still concerned that there exist duplicate copies of my blob content. One copy in the wwdoc_document$ table, and one in my custom table.
Dmitry/Oracle can you confirm this?

Upload and Download through the same button toolbar Spreadsheet

Hello,
Does anyone know if I can set up the two processes: Uploading and downloading Data Inside the Excel toolbar?
Web ADI defines the Oracle tap where the Upload and Download options are. Where Web ADI defines the Oracle tap?
Can I modify that menu and unify in the same button the upload and download processes.
My client wants to see the refreshed data inside Oracle without pushing Uploading Data and pushing again Downloading Data.

HTML tag to upload and Download files

hello all
IS there any HtTML tag to upload and download files ???
rgds
ASHWIN

Yea, for downloading you can use a normal link. For uploading, you need an html form like
<form name="form1" enctype="multipart/form-data" method="post" action="doSomething.jsp">
<input type="file" name="file">
</form>To be honest I know nothing about jsp and servlets yet, but I would guess that it works just the same as with php, with which I am alot more familiar. Basicly, the form tag with the input type="file" tag tells the form to submit your file to the webserver.
Then, whatever script you call with action="anythingYouWantHere" will handle the file the user submitted. There must be very similar functions to handle them in java than there is in php.
Things to look for with file upload that often are buggy is the permissions / security settings you have on your webserver. Sometimes you need to make a special folder with extra permissions to allow you upload to work.
Thats about all I know on this matter, good luck :)

Uploading and downloading files from a web app (Urgent!!)

Hi everyone:
I'm developing an application in PL/SQL to upload and download files from an HTML webpage. I congured the document table and the parameters necessary in the DAD of my application.
when I upload the file using my webpage that file info is automatically uploaded to the doc table. This is as far as I have gotten.
I need to do the following:
- Place the uploaded file into a column in another table in my database as part of a text message (think of it as an email message), and delete the file from the doc table (as this is thought to be a temp table that holds the file when uploaded from my webpage)
- Retreive the file so that it can be downloaded from another web page.
The file can be a PDF, WORD DOC, etc...
I now that I can do this with InterMedia but I haven't figured out how :(
Can anyone please point me to an example or some documentation that can guide me through the process.
DB VERSION: 8.1.7
IAS VERSION: 1.0.2.2
Thanks,
Carlos Abarca

The idea was for you to look at the code and get an idea of how to access the BLOB in the document table. IF you look at the procedure
insert_new_photo( new_description IN VARCHAR2,
new_location IN VARCHAR,
new_photo IN VARCHAR2 )
It shows how to access the blob that is stored in the document table. You can then copy this blob to your own table using the DBMS_LOB package.
Hope this helps,
Larry

How to upload and Download the file in a system through java programing

I am trying to upload a file as well as want to download the uploaded file in my system....I don't have any server an all.
I want to implement this in my system only .
I got this code but i don't know ,where i have to make the change and what are the parameters i have to pass.
can any one help me on this code ....please
here some piece of code
File Upload and Download Code Example
package com.resource.util;
public class FileUpload
public void upload( String ftpServer, String user, String password,
String fileName, File source ) throws MalformedURLException,
IOException
if (ftpServer != null && fileName != null && source != null)
StringBuffer sb = new StringBuffer( "ftp://" );
// check for authentication else assume its anonymous access.
if (user != null && password != null)
sb.append( user );
sb.append( ':' );
sb.append( password );
sb.append( '@' );
sb.append( ftpServer );
sb.append( '/' );
sb.append( fileName );
* type ==> a=ASCII mode, i=image (binary) mode, d= file directory
* listing
sb.append( ";type=i" );
BufferedInputStream bis = null;
BufferedOutputStream bos = null;
try
URL url = new URL( sb.toString() );
URLConnection urlc = url.openConnection();
bos = new BufferedOutputStream( urlc.getOutputStream() );
bis = new BufferedInputStream( new FileInputStream( source ) );
int i;
// read byte by byte until end of stream
while ((i = bis.read()) != -1)
bos.write( i );
finally
if (bis != null)
try
bis.close();
catch (IOException ioe)
ioe.printStackTrace();
if (bos != null)
try
bos.close();
catch (IOException ioe)
ioe.printStackTrace();
else
System.out.println( "Input not available." );
}

At least that is what the code you posted suggests to me.It looks like that to me too.
I believe that
URLConnection urlc = url.openConnection(url);Will return you an FTP URLConnection implementation if you pass it a ftp:// url
So for simple FTP ops, you don't need any external libs.
Actually, looking at your code, this is already what you are doing, so I really don't get this:
am not using FTP server..... i want to implement in my system only ....So How i will do.
Can you give me any idea based on this code Can you explain a bit more what you need?

Uploading and downloading blobs without wwv_flow_files

Hi,
I am currently working on oracle 10g database and application express.
i went throu the material to upload and download images, pdf from a htmldb book.
it was excellent material. but the book only gave example about loading and downloading images, pdf through flows_files.wwv_flow_files view.
it seemed like we can only d/l the pdf, images and display on htmldb report only throu flows_files.wwv_flow_files view, as in the case of the script below
select
   wff.id, htf.anchor( 'p?n=' || wff.id, wff.filename ) filename_1,
   wff.filename filename_2, ed.abstract abstract
from
   wwv_flow_files wff, easy_document ed
where
   wff.name = ed.name;but is there a way to load and download images, pdfs from my own tables without the involvement of flows_files schema.
if then how can i modify the above code to get the pdf from the following table
TableA (vessel number, cruise number, pdf blob)
here for every (vessel, cruise) combination there is a pdf.
how can i get this pdf displayed in my htmldb report.
Can someone guide me please.
Thanks,
Philip.

Hi,
I tried the document link you gave and it looks like, i can directly download pdfs from my own tables without needding to upload to wwv_flow_files_objecst$ table.
i modified the procedure in the document accroding to my requirements and it worked.
in my page i show a grid with the parameters and the pdf documentname as download link.
when i click on the link a popup window with the option to save or open comes up.
but the popup window shows the filename as my procedure name through which i pass the id for the pdf document instaed of the filename which is shown as download link on the page.
How can i change this popup window filename to the default file name shown in the download link.
so that everytime i select the parameters, the page shows the pdf filename as link and on clicking the link the popup window should be able to show the same name shown as link.
i think this can be set either at the procedure level or at the page level.
and this is the following contents of the procedure
--        SET UP HTTP HEADER
               -- use an NVL around the mime type and
               -- if it is a null set it to application/octect
               -- application/octect may launch a download window from windows
               owa_util.mime_header( nvl('PDF','application/octet'), FALSE );
                -- set the size so the browser knows how much to download
                 htp.p('Content-length: ' || B_LEN);
                -- the filename will be used by the browser if the users does a save as
-- htp.p('Content-Disposition: attachment; filename="'||'CR'||VES||CRU||'.PDF'|| '"');
                -- close the headers
                owa_util.http_header_close;
                -- download the BLOB
                wpg_docload.download_file( BREP );and this is what i did at the page level. for that particular column i went to link option and the foll is what i gave:
Link Text: CR#VESSEL##CRUISE#.PDF
Link Attributes: target="_blank"
URL: #OWNER#.PROC_DOWNLOAD_PDFS?V=#VESSEL#&C=#CRUISE#
Here the link text is the filename that i wanted to show when saving the file.
Can someone guid eme please.
Thanks,
Philip.
