Content of BLOB column - Urgent

Hi,
I can not find a file that was uploaded using a Form Application in a BLOB column. Please could you tell me where do the file resides in the database after uploading?. If I query the table it does not appear.
Thanks

To see the content of a BLOB column from sqlplus

Hi,
I have a table which has a BLOB column.
The blobs are text files.
Is there a way to check the content of blob column from sqlplus itself.
Thanks.

There's no information about versin of database
If you're using 11g, then refer to this link:

Use either one these two fuctions...

URGENT: Problems Loading files with SQL Loader into a BLOB column

Hi friends,
I read a lot about how to load files into blob columns, but I found errors that I can't solve.
I've read several notes in these forums, ine of them:
sql loader: loading external file into blob
and tried the solutions but without good results.
Here are some of my tests:
With this .ctl:
LOAD DATA
INFILE *
INTO TABLE mytable
REPLACE
FIELDS TERMINATED BY ','
number1 INTEGER EXTERNAL,
cad1 CHAR(250),
image1 LOBFILE(cad1) TERMINATED BY EOF
BEGINDATA
1153,/opt/oracle/appl/myapp/1.0.0/img/1153.JPG,
the error when I execute sqlldr is:
SQL*Loader-350: Syntax error at line 9.
Expecting "," or ")", found "LOBFILE".
image1 LOBFILE(cad1) TERMINATED BY EOF
^
What problem exists with LOBFILE ??
(mytable of course has number1 as a NUMBER, cad1 as VARCHAR2(250) and image1 as BLOB
I tried too with :
LOAD DATA
INFILE sample.dat
INTO TABLE mytable
FIELDS TERMINATED BY ','
(cad1 CHAR(3),
cad2 FILLER CHAR(30),
image1 BFILE(CONSTANT "/opt/oracle/appl/myapp/1.0.0/img/", cad2))
sample.dat is:
1153,1153.JPEG,
and error is:
SQL*Loader-350: Syntax error at line 6.
Expecting "," or ")", found "FILLER".
cad2 FILLER CHAR(30),
^
I tried too with a procedure, but without results...
Any idea about this error messages?
Thanks a lot.

> So you think that if one person put an "urgent" in the subject is screwing the problems of
other people?
Absolutely. As you are telling them "My posting is more important than yours and deserve faster attention and resolution than yours!".
So what could a typical response be? Someone telling you that his posting is more important by using the phrase "VERY URGENT!". And the next poster may decide that, no, his problem is evern more import - and use "EXTREMELY URGENT!!" as the subject. And the next one then raises the stakes by claiming his problem is "CODE RED! CRITICAL. DEFCON 4. URGENT!!!!".
Stupid, isn't it? As stupid as your instance that there is nothing wrong with your pitiful clamoring for attention to your problem by saying it is urgent.
What does the RFC's say about a meaningful title/subject in a public forum? I trust that you know what a RFC is? After all, you claim to have used public forums on the Internet for some years now..
The RFC on "public forums" is called The Usenet Article Format. This is what it has to say about the SUBJECT of a public posting:
=
The "Subject" line (formerly "Title") tells what the message is about. It should be suggestive enough of the contents of the message to enable a reader to make a decision whether to read the message based on the subject alone. If the message is submitted in response to another message (e.g., is a follow-up) the default subject should begin with the four characters "Re: ", and the "References" line is required. For follow-ups, the use of the "Summary" line is encouraged.
=
([url http://www.cs.tut.fi/~jkorpela/rfc/1036.html]RFC 1036, the Usenet article format)
Or how about [url http://www.cs.tut.fi/~jkorpela/usenet/dont.html]The seven don'ts of Usenet?
Point 7 of the Don'ts:
Don't try to catch attention by typing something foolish like "PLEASE HELP ME!!!! URGENT!!! I NEED YOUR HELP!!!" into the Subject line. Instead, type something informative (using normal mixed case!) that describes the subject matter.
Please tell me that you are not too thick to understand the basic principles of netiquette, or to argue with the RFCs that governs the very fabric of the Internet.
As for when I have an "urgent" problem? In my "real" work? I take it up with Oracle Support on Metalink by filing an iTAR/SR. As any non-idiot should do with a real-life Oracle crisis problem.
I do not barge into a public forum like you do, jump up and down, and demand quick attention by claiming that my problem is more important and more urgent and more deserving of attention that other people's problem in the very same forum.

How To Print the contents of a BLOB Column on a report?(Word Document)

Requirement: The word document will be inserted in a BLOB Column and the data in the word document has to be shown on the reports or the user should be able to see the word document (atleast he should be able to view the contents)?
The data is getting loaded in the database but not sure how to proceed further.
Any inputs on how to proceed will be appreciated.
Thanks.

in JComponent there is a method called print(Graphics g)
you can use that with a Printable class

Download clob contents from function instead of a blob column in a table

I found some examples how to create a download link for data stored in a blob column. However my data is not stored in a blob column but is created in a function returning a clob. Obviously this function can be used to fill a blob column that can then be downloaded but maybe there is a more direct route.

Hello Rene,
I adapted one of my snippets for download-links for your case. The procedure is pretty much the same like the one concerning an existing blob. To provide the download, you need to convert your clob into a blob, which can be done easily by using the corresponding function provided by the [url http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm]DBMS_LOB-API.
The result might look like the following (untested) code snippet:
CREATE OR REPLACE procedure download_from_function (p_func_argument IN VARCHAR2, p_filename IN VARCHAR2)
AS
l_http_response UTL_HTTP.resp;
l_blob           BLOB;
l_raw            RAW(32767);
l_length         INTEGER;
l_dest_offset    INTEGER := 1;
l_src_offset     INTEGER := 1;
l_lang_context   INTGER := DBMS_LOB.DEFAULT_LANG_CTX;
l_warning        INTEGER;
BEGIN
-- Initialize the BLOB.
DBMS_LOB.createtemporary(l_blob, FALSE);
-- replace the function call for src_clob
DBMS_LOB.convertToBlob( dest_lob     => l_blob,
                          src_clob     => your_clob_function(p_func_argument),
                          amount       => DBMS_LOB.LOBMAXSIZE,
                          dest_offset => l_dest_offset,
                          src_offset   => l_src_offset,
                          blob_csid    => DBMS_LOB.DEFAULT_CSID,
                          lang_context => l_lang_context,
                          warning      => l_warning);
l_length := DBMS_LOB.getlength(l_blob);
-- create response header
OWA_UTIL.mime_header('text/plain', false);
-- add furhter header attributes
htp.p('Content-length: ' || l_length);
htp.p('Content-Disposition: attachment; filename="' || p_filename || '"');
-- close the headers
OWA_UTIL.http_header_close;
-- download the BLOB
WPG_DOCLOAD.download_file( l_blob );
-- release BLOB from memory
DBMS_LOB.freetemporary(l_blob);
EXCEPTION
WHEN OTHERS THEN
    DBMS_LOB.freetemporary(l_blob);
    RAISE;
END download_from_function;
-- Page process before header on blank page
BEGIN

                          p_filename => 'filename_for_download.txt');
END;You should change function name and arguments to fit your clob-function's signature. You may also want to add a characterset conversion if needed. See the [url http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_lob.htm]API-doc for details.

Retrieving contents of a BLOB column using XSQL

I am using a simple XSQL page to retrieve some data from a 9i database and the majority of it works fine.
When I try and retrieve data from a BLOB column I just get a stream of numbers in the result when I am expecting to see some XML data.
Query:
<xsql:query>
SELECT GLOBALINDEXEDBLOB FROM {@db} WHERE {@where}
</xsql:query>
Result:
<?xml version = '1.0'?>
<a-query db="ODMM_CONTENTSTORE" where="id=1">

<ROWSET><ROW num="1"><GLOBALINDEXEDBLOB>3C3F786D6C2076657273696F6E3D22312E30223F3E0A3C212D2D20467261676D6 ....

Any ideas what I'm doing wrong here ?

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

end array_insert;
end associative_array;
this procedure is called from .net. from .net sending blob is posiible or not.if yes how

Ok, that won't work...you need to generate an image tag and provide the contents of the blob column as the src for the image tag.
If you look at my blog entry -

and download that Whitepaper that I talk about you will find an example of how to do what you want to do. Note the majority of that whitepaper is discussing other (quite advanced) topics, but there is a small part of it that shows how to display an image stored as a blob in a table.

How to create a dynamic hyperlink which point to a BLOB column

Hello,
I am fighting with the issue for about 2 days.
My purpose is to use Oracle Report Builder to build a report of our employee directory which contains employee's information and also employee's picture. The requirement is that our report is going to generate a html file to our web server. By creating a dynamic hyperlink to the Employee's name in the report output file (the html file generated to our web server), it should then display the corresponding employee's picture which is a BLOB column stored in our oracle database.
I only can create the hyperlink for the employee's name if the link is static, like 'http://www.google.com
But from the Oracle Reports 10g Release2 (10.1.2), about the exmaple 1: Dynamic hyperlink, I refered the link
http://www.oracle.com/webapps/online-help/reports/10.1.2/state/content/navId.3/navSetId._/vtTopicFile.htmlhelp_rwbuild_hs%7Crwcontxt%7Cprops%7Cpi_lay_hyperlink%7Ehtm/
The link gave he following example shows a value for the Hyperlink property that specifies a link to a destination identified dynamically:
'DEPT_DETAILS_' || LTRIM(TO_CHAR(:DEPTNO))
where :DEPTNO is a column value retrieved from the database at runtime.
I tried as the same way to want it dynamcially shows the column :EMP_PHTOT, which is one BLOB column, but it was failed.
Anyone knows how to implement this? Any inputs is appreciated!
Thanks,
Jing

What exactly is the error messag u are getting ?
If u have a hyperlink which refers to www.oracle.com in ur pdf, does it work ?
I think simple URL from PDF will not retrieve any data from the oracle database since it has to make some database connection.
My suggestion would be whenever request for employee information comes,
extract that picture from blob and put it a virtual folder in the application server.
And from the pdf/report access the URL with reference to the picture...
