Help! Trying to write to a BLOB column

I am trying to write to a BLOB column.
I insert a row with an empty BLOB (using the emppty_blob())
I then get the locator of the blob by using a select statement
that is marked 'for update' (autocommit is set to 'false')
I use the blob.getBinaryOutputStream() method to get an
outputstream and when I write outputstream.write(byte[], 0,
length) nothing happens!?
(I am trying to write a simple byte array {1,2,3,4,5,6,7,8,9,0})
Please help!
Thanks,

Hi,
just to exclude a simple possibility:
did you call "commit" after you've inserted/updated
the blob field?
If yes, could you please post your code?

ORA_FFI and BLOB columns

I'm trying to find dll library, which can write and read blob column? Can anybody help me?

Shay, thanks for your reply.
Is my interpretation of your advice correct?
1. I need to use Java to replace the Delphi dll to allow me to copy/paste the client clipboard to/from a file.
2. If the file is on the client then I will also need to use Java in place of text_io to read from the file.
3. Could I use Java to copy to/paste from the client clipboard to a server file. That way I would not need to change the text_io code?
Thanks

POL-3314 with BLOB columns

When trying to import images into BLOB columns, or read them back we get this error on WIN32 (surprisingly there is no problem at all on any of the windows mobile platforms like mobile 5 or ppc2003)
Does anyone have a fix/work around for this?
There is a bug 5880088 with a staus of 'Closed, not feasible to fix' on metalink, with reference to a note (waiting for this from Oracle as not accessible), but would be surprised if we are the only people wanting to store images in the database

work around is to select the data for update, rather than just select the data when wanting to retrieve BLOB data

Please Help - Trying to get contents of column (RepeaterRenderer)

Hi,
I am trying to write the contents of the table to a file but without the markups. So, I am trying to obtain the contents of the column when using RepeaterRenderer. I think this is where the contents is but I have no idea how to extract it.
protected void rowBody(FacesContext context, UIData data,
ResponseWriter writer) throws IOException {
// Iterate over the UIColumn children of this UIData component
Iterator columns = data.getChildren().iterator();
int currentColumn = 0;
while (columns.hasNext()) {
// Only process UIColumn children
UIComponent column = (UIComponent) columns.next();
if (!(column instanceof UIColumn)) {
continue;
Iterator contents = column.getChildren().iterator();
while (contents.hasNext()) {
encodeRecursive(context, (UIComponent) contents.next());
currentColumn++;
So, what I am trying to do is something like "writer.write(contents.toString())" where the writer would be a Fileoutputstream object instead of a ResponseWriter. However, since contents is of type Iterator, I have no idea how do I extract the contents of the table.
Any help and suggestions are appreciated.
Thanks in advance!

Be careful when you copy the address as there is a space between
/src/compone" "nts/..... and it seems to be added even though it is not there when I posted the message.

How to load externl files (PDF) into BLOB column. Please help.

Hi All,
I've currently been working on loading many external binary files (PDF) into BLOB column. After some digging, I learn that the SQL*LOADER can be used to load data from external files into table. I also got help from another forummate mentioning to use PL/SQL procedure to do so. Since I have not done anything like this before. So, my question is what is the simple approach needed to upload PDF files into a table(there is only one table containing BLOB column in my database). In addition, the LOBs can not be query-able, I wanted to list the contents of the LOBs column to make sure that I did successfully upload data into the database. How can I do that?. I do need your help. Please direct me step by step how to do so. Your help is greatly appreciated.

Cfscript I'm trying to write Please help :)

I wonder if some one could help with a cfscript I'm trying to write.
A have a number eg
135
4245
1
I want to turn these into a string with length 6 with zeros at the start like so:
000135
004245
000001
thx 4 any ideas

Here's a cfscript along the lines of what you asked for. There's other ways to do it, of course, but I thought this approach would be helpful to you.
<cfscript>
/* takes a string as an argument and adds as many zeroes as it takes to make the string be exactly 6 characters. */
function PadWithZeroes()
var VarToTest = "";
var ValToReturn = "";
var VarLen = 0;
var DesiredVarLen = 6;
if (StructCount(Arguments) EQ 1)
 /* Use Trim(Arguments[1]) only if you do NOT want to add zeroes to one or more empty spaces */
 VarToTest = Trim(Arguments[1]);
 VarLen = Len(VarToTest);
 TimesToLoop = DesiredVarLen - VarLen;
if (TimesToLoop GT 0)
 for (q = 1; q LTE TimesToLoop; q = q + 1)
 VarToTest = "0" & VarToTest;
 ValToReturn = VarToTest;
 return ValToReturn;
else
 return false;
// the rest is for testing/viewing the function etc.
NumberToUse = 4;
if (IsDefined("URL.NumberToUse") AND Len(Trim(URL.NumberToUse)) LTE 6)
 NumberToUse = Trim(URL.NumberToUse);
</cfscript>
<cfoutput>
 
NumberToUse=#NumberToUse#
 
 
PadWithZeroes(NumberToUse) = #PadWithZeroes(NumberToUse)#

How to display binary file saved in BLOB column in Discoverer PLUS /VIEWER

HI, Friends,
I tried to display the binary file saved in the database in BLOB column with the *.doc or *.xls fomats, but it seemed not work at all. I can display them in discoverer DESKTOP, but not the web version PLUS or VIEWER. MY Discoverer PLUS/VIEWER version is 9.0.4.45.02 and the database is 9.2.0.4. Are there any special setting/configuration in somewhere (Discoverer administration/Applicaiton server/PLUS/VIEWER?)
Any help /information will be greatly appreciated.
Thanks a lot.

Hi,
Sorry but this feature is not available in the web version of 9.0.4.45. You will have to write your own mod_plsql function to download the file.

Load JAR from BLOB column?

I have a JAR file that load and works find when I use the loadjava utility, but my software is now being deployed to a server that I don't have remote access to and can't connect remotely to the Oracle database. I need to push out updated JAR files periodically and would like to automate the updates without requiring help from their DBA.
Is it possible to load my JAR into a BLOB column in the database and then have it loaded from that? In my testing it appears that I can do that for a single class, but I'd like to do the entire JAR. I've tried CREATE JAVA ... USING BLOB, but that appears to be expecting a character stream (java source).
My software is on a separate server from the database, so I don't think I can use a BFILE???
We're using Oracle 10g.
Thanks!

Hi
Sure you can do that :)
I have done a CMS Application Archive importer into DBPrism CMS.
Look at the code (importDir function):
http://dbprism.cvs.sourceforge.net/viewvc/dbprism/cms-2.1/src/com/prism/cms/core/Util.java?revision=1.10&view=markup
First you has to iterate on each entry of the JAR using ZipInputStream class, then for each entry you can create a temporary BLOB to process each "create java class using .." SQL operations.
Here a code snipped:
695 BLOB newContent =
696 BLOB.createTemporary(conn, true, BLOB
697 .DURATION_SESSION);
698 OutputStream ow = newContent.setBinaryStream(1L);
699 while ((size = jin.read(buff, 0, buff.length)) > 0)
700 ow.write(buff, 0, size);
701 ow.flush();
702 ow.close();
703 ow = null;
704 cs.setBLOB(1, newContent);
705 cs.setString(2,(isResource) ? "java resource" : "java source");
706 cs.setString(3, classOrResourceName);
707 cs.registerOutParameter(4,Types.VARCHAR);
708 try {
709 cs.executeUpdate();
710 String loadedClass = cs.getString(4);
711 if (!isResource)
712 listOfLoadedClasses.put(loadedClass,classOrResourceName);
713 log.debug(".importDir - OK loading: "+loadedClass);
714 } catch (SQLException s) {
715 log.warn(".importDir - Error loading: "+classOrResourceName,s);
716 } finally {
717 newContent.freeTemporary();
718 }
cs is:
674 cs =
675 (OracleCallableStatement)conn.prepareCall("{ call begin\n" +
676 " update create$java$lob$table set LOB = ?, loadtime=sysdate where name = 'LOADJAVA/LOB/KEY';\n" +
677 " execute immediate 'create or replace '||?||' named \"'||?||'\" using ''LOADJAVA/LOB/KEY''';\n" +
678 " ? := \"NameFromLastDDL\"(0);\n" +
679 " end }");
Hope this help, Marcelo.

On another note it's always a good idea to tell us what database version you are using e.g. 9.2.0.7 or 10.2.0.3 etc. as this will allow us to tailor our answers appropriately in case there are features we can't use because you are using an older version.
And, when posting code, please put {noformat}{noformat} tags around it so that it keeps its formatting on the forum.

Help, how to open and display blobs from tables

Dear all,
I am trying to store ms-word files on a table using a blob column.
Does anyone how to open the files and display them from a form using 9iAS?
Thank you.
Carlos.

And there may be, but you won't likely find that here. Do some time searching Google and maybe you'll find code that someone was nice enough to make freely available, although I wouldn't count on it. Were i a programmer and took the time to read those docs and write the code, I'd want to be paid for my time. But there are a lot of programmers who swear by freeware! You may get lucky.

How to view PDF files strored in a BLOB column

Hi all,
I want to display a PDF file, stored in a BLOB column, in a form or through a JavaBean.
But the problem is more complicated then that. I do not want to retrieve the PDF file in the application server that show it through a browser.
Actually, I do not want users to get the entire file, I just want them to see it or print it.
I want, in fact, to display a "stream" of bytes through Oracle Forms. Not a file.
This one, sounded to be a good solution, but actually not. When the file was too big (multiple pages), the application was blocked until the entire file was loaded. And when you try to print it, it wasn't printed right. The advantage of this solution is that it is open-source so we can add methods to connect to the DB, retrieve the content of the BLOB column and displays it without downloading the file.
Here is a good solution. Really good, files are loaded quickly, the rendering is really good and the file is printed perfectly (as it was printed from Adobe Acrobat). The disadvantage of this solution is that it is not open-source and is really expansive.
As you can see, both solutions uses PJC.
So any help, any idea to solve my problem will be highly appreciated.
Thanks to all of you,
Amine
PS : I am using F&R 11gR2

Not entirely. At least we came to the conclusion it doesn't make (much) sense to block the save option of PDFs if you want to allow printing them
Anyway; there is of course another possibilty: you could always write your own java bean PDF reader; there are plenty of java PDF libraries available:
Open Source PDF Libraries in Java
The easiest way would be to choose one which can open a PDF from a URL and render it; I would retrieve the image via mod_plsql using WPG_DOCLOAD and simply use the PDF library to render the PDF. No tempfiles anyway, and if you don't implement it there is also no save button.
cheers

Hello,
I am getting the following errors when I am trying to
insert in a BLOB in the oracle 9i database:
java.sql.SQLException: ORA-00604: error occurred
at recursive SQL level 1 ORA-06502: PL/SQL: numeric
or value error ORA-06512: at line 205 ORA-22297:
warning: Open LOBs exist at transaction commit
time
You're doing exactly what the error says, that is committing with an open LOB. Look at the following piece of code: you write in the LOB, you flush it and then commit. There is no closing of the LOB stream before committing.
Try putting the tempBlobOStream.close() instruction before the commit.
// Write the data into the temporary CLOB from the
he byte array
          tempBlobOStream.write(ba);
          // Flush and close the stream
          tempBlobOStream.flush();
nn.commit();
          //Close everything
tempBlobOStream.close();

Need to create link to Word Doc in blob column in search results report

I got the Oracle Text boolean search of word documents in a blob column of a table working.
Now I need to be able to create a link in the results report.
I know that Oracle creates a link for each document in the column when you attach a file, I just need to know what the link should be to allow users to open the document in the search results report.
Right now the application is set to do a search in the attached word documents, and in the results window it shows the names of the people who match the search, but it won't allow me to create a link to their resume in the results report.
the name of the table is CONTRACTOR_LIST and the blob column is RESUME.
How would you go about creating a simple link to the word file in the results window?
Here is the code for the query
select score(1) relevance, Name, Resume
from contractor_list
where CONTAINS (resume, :P1_SEARCH, 1) > 0
order by 1 desc
That works, but I can't get it to link to the resume file.
Here is the code I'm using for the link
javascript:popupURL("#RESUMEL#")
This just give me an error page and the the link is
http://server-namer:8080/apex/[datatype]
the error is
Bad Request
The HTTP client sent a request that this server could not understand.
Thanks again!

It is within the table I believe (I'm not a DBA or a developer) since I created a BLOB column and then used the file browse feature to allow users to attach a resume to the table in order to be able to perform a search of the attached documents.
I'm just having a hard time pointing the link in the search results report to the document in the blob column.
The information on that page is great if you're trying to create a link to the document on the initial report.
But I created a query using Oracle Text to run a report that does a boolean search of the attached word documents in the table.
When it displays the search results, it doesn't create a link to the document and I can't figure out how to do it.
Here's a link the the instructions I used to create the initial search report with Oracle Text, mind you I only created the index and query, I didn't add in all the link data since they're using documents on websites and I'm using documents in a table.

If you can help me with this I'd really appreciate it.
Thanks again.
