CSV to Oracle DB - Upload File

Dear All,
I have a scenario where I need to upload data in csv format to tables in Oracle DB. Here is the detailed description of problem.
a) User selects a csv file on his desktop which has data in it in csv format.
b) A BLOB is inserted in Oracle DB table "FileData_Tab" once user clicks on upload button.
c) A row insert trigger will be invoked on inserting the data which invokes a <b>stored procedure to reconstruct the csv file, read the data from it, and update the data accordingly to respective tables fields</b>.
My only concern is in step 'c'. Is it possible in Oracle to have a stored procedure which re-constructs a csv file, and updates the tables.
Thanks in advance.
Regards,
Chaitanya

Here you have an article I used to get csv from an oracle cursor with pl/sql functions. There is another to insert from a csv. They are very simple. Maybe it could be help for you with a little modification.

Uploaded Files stored in Oracle 10G database or in Unix File system

Hey All,
I am trying to understand best practices on storing uploaded files. Should you store within the database itself (this is the current method we are using by leveraging BLOB storage) or use a BFILE locator to use the files system storage (we have our DB's on UNIX) . . .or is there another method I should be entertaining? I have read arguments on both sides of this question. I wanted to see what answers forum readers could provide!! I understand there are quite a few factors but the situation I am in is as follows:
1) Storing text and pdf documents.
2) File sizes range from a few Kb to up to 15MB in size
3) uploaded files can be deleted and updated / replaced quite frequently
Right now we have an Oracle stored procedure that is uploading the files binary data into a BLOB column on our table. We have no real "performance" problems with this method but are entertaining the idea of using the UNIX file system for storage instead of the database.
Thanks for the insight!!

Anthony,
First word you must learn here in this forum is RESPECT.
If you require any further explanation, just say so.
BLOB compared with BFILE
Security:
BFILEs are inherently insecure, as insecure as your operating system (OS).
Features:
BFILEs are not writable from typical database APIs whereas BLOBs are.
One of the most important features is that BLOBs can participate in transactions and are recoverable. Not so for BFILEs.
Performance:
Roughly the same.
Upping the size of your buffer cache can make a BIG improvement in BLOB performance.
BLOBs can be configured to exist in Oracle's cache which should make repeated/multiple reads faster.
Piece wise/non-sequential access of a BLOB is known to be faster than a that of a BFILE.
Manageability:
Only the BFILE locator is stored in an Oracle BACKUP. One needs to do a separate backup to save the OS file that the BFILE locator points to. The BLOB data is backed up along with the rest of the database data.
Storage:
The amount of table space required to store file data in a BLOB will be larger than that of the file itself due to LOB index which is the reason for better BLOB performance for piece wise random access of the BLOB value.

Upload file in JSP with Oracle Database 10gR2

How to upload file with oracle database 10gR2??
i can't find how to upload..
i've tried to create a procedure in oracle and execute in netbeans but the file save in directory and then from directory save to database.
it means the file save in 2 location, in directory and database..
does anybody know how to save file direct from the JSP file into database without save in directory?
this is the procedure..
create or replace PROCEDURE load_file (
p_id number,
p_photo_name in varchar2) IS
src_file BFILE;
dst_file BLOB;
lgh_file BINARY_INTEGER;
BEGIN
src_file := bfilename('DIR_TEMP', p_photo_name);
-- insert a NULL record to lock
INSERT INTO temp_photo
*(id, photo_name, photo)*
VALUES
*(p_id , p_photo_name ,EMPTY_BLOB())*
RETURNING photo INTO dst_file;
-- lock record
SELECT photo
INTO dst_file
FROM temp_photo
WHERE id = p_id
AND photo_name = p_photo_name
FOR UPDATE;
-- open the file
dbms_lob.fileopen(src_file, dbms_lob.file_readonly);
-- determine length
lgh_file := dbms_lob.getlength(src_file);
-- read the file
dbms_lob.loadfromfile(dst_file, src_file, lgh_file);
-- update the blob field
UPDATE temp_photo
SET photo = dst_file
WHERE id = p_id
AND photo_name = p_photo_name;
-- close file
dbms_lob.fileclose(src_file);
END load_file;

Well your Oracle procedure is designed to load a file, so that's what it does. If you want it to load from a data stream such as an upload, you need to rewrite it accordingly.
So far this is not a Java question at all.

Uploading File with Umlaute (German) - solved

I am using the .csv to table package from Vikas. The uploaded file comes from one of
my customers. The customer is supposed to save an .xls file as .csv and upload it into
a collection. So far so good. Whenever there are Umlaute (ä, ö, ü), they are not translated
properly and the collection shows a character ¿ instead. So, a REPLACE would not work
there. Is there any experience on how to solve this problem? I have no chance to educate
my customer not to use Umlaute or to ask him to check the settings in their excel, since
they are numerous and anonymous.

Okay,
With a little help from John Scott, I found a solution changing this part of the package to:
FOR i IN 1 .. l_record.COUNT
         LOOP
            htmldb_collection.update_member_attribute
                                     (p_collection_name      => p_collection_name,
                                      p_seq                  => l_seq_id,
                                      p_attr_number          => i,
                                      p_attr_value           => CONVERT
                                                                   (l_record
                                                                           (i),
                                                                    'UTF8',
                                                                    'WE8ISO8859P1'
         END LOOP;and it works properly for the German characters.

You could try using an Excel VB script to do it. I'm considering doing the same thing. We receive reports from vendors in Excel spreadsheet formats currently. The users are now forced to save the document as a CSV file and then call up an Oracle Forms page and enter the CSV filename. I use the utility TEXT_IO to read the file in its comma delimited form. For me, this process is highly dependant on the user correctly saving the file. This causes me to perform very specific data format checking in my PL scripts. To alleviate this, I'm considering using the VB script as I mentioned. I haven't investigated it, its just an idea. Of course it'll be dependent on whether I can connect to the Oracle DB within the VB script in Excel.
Good luck.

UPLOAD FILE

Hi.. i did some research on loading the csv file, and its pretty cool. But I ran into this problem, I was uploading test.csv file as given here
Re: Loading a CSV file into a table(Vikas Plz)
and mainly the demo provided by Vikas.
and it works pretty well. But when my csv file gets bigger in size, although i can see the data is getting inserted into the table, but the front end session is timing out.
So I thought if i can upload test.csv to wwv_flow_files and then using UTL_FILE, i can transfer it to the unix box and then run some scripts. WHY? bcos our team is already doing this kind of thing.. load csv file to unix box and insert data of csv file to the tables. So its pretty much done.. only thing is to provide capability to upload the file to unix box.
Does it make sense? If yes.. then how can i upload file to wwv_flow_files using File browse item.
Suggestions / Ideas?

Remove link for uploaded files in application

Hi all,
I've been following the tutorial on how to upload and download files in application at http://download-uk.oracle.com/docs/cd/B32472_01/doc/appdev.300/b32469/up_dn_files.htm. I have now created my own table which stores the uploaded files and can download them successfully. I would now like to add the ability to delete these files within the application and was wondering what the best way of doing this was?
I would like to add another column to the displayed report with a 'Remove file' link for each listed file, which when clicked would delete the file from the table. I've already tried using a similar method to the one used to upload the files (instead of uploading the file, the called procedure deletes it from the table using the specified ID), but this causes the application to display a blank page when the link is clicked, which I dont want (but does delete the file).
I would appreciate any suggestions.
Regards,
Dave

Delete an uploaded file (in custom table) from a report

Hi,
I have a report of uploaded files (the files are saved in my own table, not in APEX_APPLICATION_FILES) - I'd like to add a delete link to each file in my report so that the user can delete a particular file.
How do I go about doing this?
Thanks.

Melissa,
It is now working. You missed couple of things:
1. javascript in the header
2. you were pointing to the page 1 and your process was on the page 2
3. you passed the value to a non existing item on the page 3
4. the request which would fire the delete process was triggered by a wrong request

Is there a way to silently upload files?

Ok, so I've taken the plunge. I've started working on an AIR
app using Flash CS3. I'm putting together a little app that will
keep my online store updated with all the product updates from our
wholesaler. This includes parsing a csv file, downloading product
images from the wholesaler, updating the database, and then
uploading the images to our server.
The problem is that AIR does not seem to have the
functionality to silently upload files! Sure, I can use the
file.reference object to fire off the browse method, which then
opens the OS file browser window BUT I would really like the whole
thing to be hands off. In the past, I've written these types of
apps using Visual Studio but I haven't touched VS in two years.
Has anyone run across a way to silently upload or ftp files
in AIR?

Hey Oliver,
Thanks for your answer--the fact that it CAN be done has
gotten me a lot further on finding a solution. Here's what I have
so far. As it runs, I can see the progress and completion of the
upload but I'm still not getting it saved. I'm uploading it to a
ColdFusion processing page.
AS3 Code:
import flash.filesystem.*;
import flash.net.URLRequest;
//Silent File Upload (no browse window)
function imageUpload(imageName,uploadPage):void
trace('Starting Upload of ' + imageName + '\n');
var myFile:File =
File.applicationDirectory.resolvePath(imageName);
var request:URLRequest = new URLRequest(uploadPage);
request.method = URLRequestMethod.POST;
myFile.addEventListener(ProgressEvent.PROGRESS,progressHandler);
myFile.addEventListener(Event.COMPLETE,completeHandler);
myFile.upload(request,"theFile");
function progressHandler(event:ProgressEvent):void {
var file:FileReference = FileReference(event.target);
var pLoaded =
Math.ceil(event.bytesLoaded/event.bytesTotal*100);
trace(pLoaded + '% uploaded');
function completeHandler(event:Event):void
trace ('Upload complete.');
var uploadPage = "
http://www.aaronbday.com/upload_file.cfm";
imageUpload("angelic_cat.jpg",uploadPage);
Here's the CFM page:

Upload file to global directory in Dev, Q&A and Prod!

I have an upload application in BSP, that uploads files to for example /usr/sap/BWD/files
this works in Development, but of course this directory is not available in Production, so BSP won't work there.
Isn't it possible to use one global directory?
Right now somebody created for us a directory, that's the same on all 3 systems (Dev, Q, and Production)
this dir is
on Development: DIR_TRANS     /usr/sap/transBW
on Quality: DIR_TRANS     /usr/sap/transBW
on Production: DIR_TRANS     /usr/sap/trans
notice the small difference in path in Production... Is there a way to use the DIR_TRANS instead of the real path?
my application writes data like this:
fname = '/usr/sap/CBD/files/FILE.CSV'.
OPEN DATASET fname FOR OUTPUT in TEXT MODE encoding default.
if sy-subrc gt 0.
WRITE: / 'Error opening file'.
endif.
LOOP AT data_TAB INTO LIN.
TRANSFER LIN TO FNAME.
ENDLOOP.
CLOSE DATASET FNAME.
thanks a lot, points will be rewarded for usefull answers!
thanks!

use transaction FILE to create logical path for the actual file path.
and then use FM
call function 'FILE_GET_NAME'

Hello i had exactly the same error, but not with file upload.
I'm sure you have in your application lib directory to jars which aren't compatible to each other.
And the problem occured between my myfaces and tomahawk jars .
See this page:
http://wiki.apache.org/myfaces/CompatibilityMatrix
It tells you which myfaces and tomahawk jars you can use together.
Hope it can help.
bye

Error while uploading files to AWS S3

Hello Experts
SAP PI 7.31
I am working on the following scenario. SAP PI receives a file attachment from SOAP response and the same needs to be uploaded to AWS S3 using REST (Advantco REST Adapter) (PUT Method):
File --> SAP PI --> REST
||
SOAP
To do this without using BPM, I am using RequestResponseBean and ResponseOnewayBean in Sender_File Adapter. In the module parameters, I have mentioned the details of the REST receiver channel. I am using PUT method in Receiver_REST and have checked option "keep attachments"
When I run this interface, the message fails while sending the file to Receiver_REST with the following errors:
Sender_File: ResponseOnewayBean - Attempt to process file failed with com.sap.engine.interfaces.messaging.api.exception.MessagingException: com.sap.aii.af.lib.ra.cci.XIAdapterException
Receiver_REST Adapter: Error: Broken pipe (Software version: 1.0.11)
This is the first time we are using REST Adapter to upload files to AWS S3. Could you please provide pointers on the same?
Thanks
Jaya

05/08/17 11:22:31 java.io.IOException: java.io.IOException: sqlldr: not found
Does the client m/c have sqlldr installed (it will need Oracle client installation)? Does it have the ORACLE_HOME/bin directory in whatever path is appropriate for the client OS?
Cheers, APC

Fileaccess.httpUploadBean doesn't upload file in Jdevelper 9.0.3

Hi,
I am using Jdevelper 9.0.3 to develop a jsp Based File Upload Utility.
I have attached Liberary "JSP RUNTIME" which reffers to "ojsp.jar","ojsputil.jar","oc4j.jar","servlet.jar","ojc.jar".
while running the code for file upload, file doesn't get uploaded. I am not getting any exceptions too.
But the same pease of code with same liberary "JSP RUNTIME" is working absolutly fine(Uploading File), when i am running it using Jdeveloper10.1.2, and This is Strange to me.Actualy i need to use Jdeveloper9.0.3 only.Please let me know if any patch is required to apply in Jdeveloper9.0.3.
Please find the code below and help.
