Updating blob files

can somebody help me, can mysql update blob data fields? or is there another way to change data i blob columns/...

Hi,
I've done this before in Oracle so not sure about mysql.
In Oracle, we have to insert a row into the database with an empty BLOB using the empty_blob() function within Oracle.
Then its a matter of calling a select on the row for UPDATE and streaming the BLOB into the database.
eg.
String sql = "INSERT into TABLE values (a,empty_blob());
... execute sql
then select on the table like this
String sql = "Select BLOB from TABLE where id = a for UPDATE; (Where BLOB is your Blob column name)
execute sql and the BLOB value returned can be used
BLOB blob = (BLOB)rs.getBlob(1);
I had to cast from the java.sql.Blob type to the oracle.sql.BLOB type then get an output stream and stream your data in. I used a byte[] to do this.
I'm not sure how you would go about this in mysql but maybe I've pointed you in the right direction.
hope this helps

Using File Browse to update stored file

Hi all,
I have a form with a File Browse item on it which is (surprisingly!) used to upload a file and associate with a record. The filename is stored in a varchar column in the table. This works fine when I create (INSERT) the initial record and I can retrieve the stored file just fine. However the problem I have is when I want to update the uploaded file. It seems the normal mechanisms for update / save requests don't apply to uploaded files. My other attributes get updated fine but the new uploaded filename is not reflected in the table.
I've put together a simple example of this on a when apex.oracle.com :
http://apex.oracle.com/pls/otn/f?p=40740
Which has two fields, a file name and an 'attribute'. Try as I might I can't update the file name although the attribute changes just fine.
Any suggestions will be much appreciated. I realise I may be missing something fundamental here and am more than happy to be enlightened.
FYI, the purpose for such functionality is to allow users of our system to store a photograph of themselves along with their details. This functionality is required to allow the photograph to be updated if required.
Thanks,
Steve

If i am not mistaking, using a file browser item type will not set the uploaded file (blob) in this item, to be processed in the standard processing on you're page.
In a recent project i wrote a stored procedure for handling with uploaded files. This procedure, which based on the filename ( Fnnnn/<filename> ) , select the uploaded content through apex_application_files, the location apex saves the files. and procedure outputted the file as a blob, which then can be used to insert/update in youre table
Hope this example code will help you:
procedure upload_bestand( p_file_name in varchar2
, p_file out nocopy blob
, p_filetype out nocopy varchar2 )
is
-- Cursor voor bepalen bestand uit apex_application+files
cursor c_file ( b_file_name in varchar2)
is
select aaf.filename
, aaf.mime_type
, aaf.blob_content
from apex_application_files aaf
where aaf.name = b_file_name
r_file c_file%rowtype;
begin
open c_file ( b_file_name => p_file_name );
fetch c_file into r_file;
if c_file%notfound
then
-- Upload van bestand niet geslaagd
close c_file;
raise e_file_err;
end if;
close c_file;
-- Geupload bestand uit temp_upload tabel verwijdern
delete from apex_application_files
where name = p_file_name
commit;
p_file := r_file.blob_content;
p_filetype := r_file.mime_type;
end upload_bestand;

Updating Blob

I am trying to write a java program to update blob in db. I am reading binary from filer and trying to update the blob. So table that has payload I am saying
update A
payload = ?
where A.id = 1
But I am getting ORA-00900: invalid SQL statement error.
In java program I am setting BinaryStream. something like
String SQL = "udpate fp set payload = ? where id = " + s + " and length(raw_payload) > 0 ";
System.out.println(SQL);
// Prepare a Statement:
PreparedStatement stat= conn.prepareStatement(SQL);
// Execute
try {
File f = new File("blob_upd.dat");
BufferedInputStream b = new BufferedInputStream(new FileInputStream(f));
stat.setBinaryStream(1,b,(int)f.length());
System.out.println("Number of rows updated " + stat.executeQuery());
b.close();

I have recently updated Morgan's Library at www.psoug.org with a demo of Oracle's new DICOM data type that involves updating a BLOB.
Compare my working demo with what you are doing.

I created this stored procedure to load blob file:

IF DBMS_LOB.FILEEXISTS(SRC_FILE) = 1 THEN
UPDATE TAB_BLOB
SET FILE_FISICO = EMPTY_BLOB()
WHERE IMMOBILE = REC_CUR.IMMOBILE;
SELECT FILE_FISICO

COMMIT;
END LOAD_FILE_BLOB;
but when I run:
execute LOAD_FILE_BLOB;
I get this error:

I think that the error is on:

How can I change my stored procedure to load files blob?
Thanks in advance!

I changed so:

To use servlets u have indeed to update your web.xml...Well I'm not sure this is relevant to your case anyway.
You have to add a <servlet> element to this file.
Something like this:
<servlet>
<servlet-name>blabla</servlet-name>
<servlet-class>blablapackage.Blablaclass</servlet-class>
<init-param>...</init-param>
</servlet>
Now this may not solve your problem. Make sure you refer to your servlets using their full qualified names.btw, just to be sure, what is your definition of "servlet"? (i mean: any java class or only javax.servlet.Servlet)

How do I update a file in an Applet's JAR file from the Applet code

Here's my problem.
My applet is using a serializable history data in which I am storing in the applet's JAR file. When I run the applet, I read the file with "getResourceAsStream()" and run my program with that hist data. When my applet is closed, I need to update this file from my Applet's code and I dumfounded about how to do that.
Is there any way to update a file in the Applet's JAR file through the Java Applet code? (i.e. OutputStream?).
Would appreciate any advice people have.

Just place a copy of the file on the local hard disk and update that. When you start the Applet you try to read from the hard disk. If the file exists then no problem otherwise copy it from the jar to the hard disk.

Instead of the move statement you need to use the append work area to internal table statement. you need to have the same structure for the work area and the internal tbale.
Then use the modify data base table from internal table statement.

Peter Spier,
I have been trying to download InDesign and Photoshop for a long time. However, I found out that the programs that I have were all ready installed when I was given the computer. I got in touch with the people and through some questions it was discovered that I need to have Windows 7 for the programs to be compatible. I sent the 11 page Upgrade Advisor Report to Boston for review. Give me a few days to see if I can resolve the problem. Then I will get in touch with you to see what you recommend.
Thank you.

Error While Opening an Updated JAR file

Frnds,
I have some problem with a JAR file update. Seek ur help in this regard.Here goes my problem.
I need to update a jar file ( need to replace a single .class file with a new one ). I updated the JAR file using ' jar uf ' command and it was successfull.. I removed the old JAR file and replaced it with the updated JAR file. But when i tried to invoke the JAR application using Java we start iam unable to open the applicaiton. But when i replace this upadted JAR file with the old JAR file ( using the backup) the application loads correctly.
The application is hposted in Apcahe web server. Is a server restart required after deploying the updated JAR file or is this porblem due to some other reasons.
Thanks in advance.

It appears that the New Report .vi only accepts the .xlt template format and not .xltx as one would commonly expect. I am currently working to determine for sure that this is the case, but it does run (mostly) properly on my end if you make that change.
When I say mostly, I mean there are a couple other minor issues with your code. First the first frame of your sequence structure is really accomplishing anything. If your intent is to open a reference to the excel template, there is no need because the New Report .vi does it automatically.
Second, you will need a file path of some sort wired in to your Save Report to File .vi or else you will get a different error message after fixing the .xlt issue. I am currently researching whether this should be marked as a required terminal instead of recommended so that it not being wired would result in a broken run arrow rather than an error.
Let me know if these suggestions resolve your issue, or if I can provide further input on what you are doing in your first frame. I will touch base again once I determine whether these are expected behaviors or bugs.

OAM Context showing error when updating context file on 11i apps

HI,
When i am trying to update context file using OAM, i am getting following error.
Failed when writing Context Configuration files back to file system. Possible causes: An error occurred while attempting to establish an Applications File Server connection with the node FNDFSP_dbora12. There may be a network configuration problem, or the TNS listener on node FNDFSP_dbora12 may not be running. Please contact your system administrator. . However, you still can run AutoConfig and restart services to make sure these settings take effects.

Sawwan,
What is the application release? OS?
HP Unix
Has this ever worked? If yes, what changes have been done recently?
This is cloned environment.
Do you have proper entry in the hosts file?
yes
Is the application listener up and running? Can you view the concurrent requests log/output files? If not, please see (Note: 117012.1 - Troubleshooting the "Error Occurred While Attempting to Establish an Applications File Server Connection").
yes application listener is up and running.
Is the value "FNDFSP_dbora12" correct or it points to the source instance in case this is a cloned one? If the value is incorrect, please validate the entries in FND_NODES table (purge the table and run AutoConfig -- I believe you are familiar with the steps
Value of RRA: Service Prefix is FNDSP_ not FNDSP_dbora12.

"Ipod Cannot Be Updated, The File Required Is Missing" - Can someone help?

I just got this error today and its bugging me.
Whenever I try to update my ipod it gives me a new window saying "IPOD (name) cannot be updated, the file required is missing."
ummm I thought maybe if i restored my ipod the file would be restored too but that didnt work....
After i restored it, the itunes library updated my ipod with all my original playlists and videos, but now when i try to update it and sync my pictures to it or create new playlists, it gives me that message.
Can anyone give me some advice on what i can do to fix this problem? i do have the iTunes 7.01 my ipod is the 60G Ipod Video (White)
Thanks for your help guys, i really need it.

I just dealt with the same problem. None of the answers people gave to the problem worked!
Whatever it is that you're trying to put into your iPod... make sure that the file is located in your "My Music" file first.
Basically, when you get that message double check and if what you selected isn't in "My Music" drag and drop into it and try again.
I hope that helped!
I know... so frustrating.
