BLOB Column
I have a table with the following structure.....
CREATE TABLE "LFEE_UPLOAD"
"UPLOAD_ID" NUMBER,
"DDO_ID" VARCHAR2(12 BYTE),
"EDT" TIMESTAMP (6) DEFAULT sysdate,
"LUDT" TIMESTAMP (6) DEFAULT sysdate,
"FILENAME" VARCHAR2(50 BYTE),
"TYPE" VARCHAR2(100 BYTE),
"NOTES" VARCHAR2(100 BYTE),
"BILL_TYPE" VARCHAR2(50 BYTE) DEFAULT 'ALL',
"RECOVERY_DT" VARCHAR2(20 BYTE),
"FILE_F" BLOB,
"STATUS" VARCHAR2(20 BYTE)
now in the column "FILE_F" which contain a TEXT-FILE iin the binary large object type....................
whose value is something like this:::
243890##28-3-2011#185#RKP#02#TYPE B, R.K. PURAM, Block/Sector : XII, 904, DELHI#Shri. S. K. NAGI#Asstt. Director of Estates#
Each separated by symbol '#'...
Now the problem is this, I want to store that FILE_F column into my another table, with each column generate based on the separated values in the text file....
so plz help me???
if you are inserting into a separate table then INSERT as follows;
SQL> insert into Lfee_Upload_test
2 (
3 Upload_ID
4 ,DDO_ID
5 )
6 (
7 select Upload_ID
8 ,DDO_ID
9 from
10 (
11 with t as
12 (
13 select utl_raw.cast_to_varchar2(file_f) txt
14 from lfee_upload
15 )
16 select substr(t.txt, 1, instr(t.txt, '#')-1) as Upload_ID
17 ,substr(t.txt, instr(t.txt, '#'), (instr(t.txt, '#',1, 2)-1) - instr(t.txt, '#') ) as DDO_ID
18 from t
19 )
20 )
21 /
1 row created.I have not specified all columns, so have a play around with SUBSTR, INSTR and TO_DATE for EDT, LUDT to
extract the relevant text for each specific column.
If you want to update the same table, then maybe something like this;
update
SQL> update (
2 select Upload_ID
3 ,DDO_ID
4 ,utl_raw.cast_to_varchar2(file_f) as txt
5 from lfee_Upload)
6 set Upload_ID = substr(txt, 1, instr(txt, '#')-1)
7 ,DDO_ID = substr(txt, instr(txt, '#'), (instr(txt, '#',1, 2)-1) - instr(txt, '#') )
8 /
1 row updated.

Error while importing a table with BLOB column
Hi,
I am having a table with BLOB column. When I export such a table it gets exported correctly, but when I import the same in different schema having different tablespace it throws error

I used the import command as follows :

What can I do so that this table gets imported correctly?
Also tell me "whether the BLOB is stored in different tablespace than the default tablespace of the user?"
Thanks in advance.Hello,
U can either
1) create a tablespace with the same name in destination where you are trying to import.
2) get the ddl of the table, modify the tablespace name to reflect the existing tablespace name in destination and run the ddl in the destination database, and run your import command with option ignore=y--> which will ignore all the create errors.

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 11gR2Not 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.

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(); -

How to read BLOB column from a table in SQL or PL/SQL

this procedure is called from .net. from .net sending blob is posiible or not.if yes howOk, 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 -

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!
Edited by: gjones77 on Dec 2, 2008 6:14 AM
Edited by: gjones77 on Dec 2, 2008 7:08 AMIt 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.

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!

JingWhat 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...

How to generate a .pdf output for a BLOB column?
Hi friends,

How to show pdf or word icons for a BLOB column in a report?
Hi,
I am getting interested for the blob columns, I have created some columns for storing some pdf drawings and pictures for specific items in a table, it is ok to show a text like 'download' or any other text in the report by setting the following blob attribute:
DOWNLOAD:TICKET_DETAILS:ATTACHMENT:TICKET_DETAILS_ID::MIME_TYPE:FILE_NAME:::inline:Download
but instead of texts, I would like to show a small pdf image for my Blob file, or a word image or Excel image, according to the different file type.
how to do that?
and instead of inline or attachment this two options, I would like when the user click the image of the file, the browser will show the image in a new window, or a new browser tab.
I tried the inline option for my file at Google Chrome, but when it showed the pdf file within the browser, I cannot get back to my app by clicking the 'backward' icon at the browser menu, it will stuck there and I have to close the broswer and then login to the app again, instead of simply returning back to the previous page within the app.

Please refer to "Working With BLOBs Procedurally" section of this APEX 3.2 documentation for more: [url http://download.oracle.com/docs/cd/E14373_01/appdev.32/e11838/advnc.htm#sthref2199]http://download.oracle.com/docs/cd/E14373_01/appdev.32/e11838/advnc.htm#sthref2199
Also I have the gif images representing various MIME types on my file server. For e.g., /i/excel_icon.gif. You can use #WORKSPACE_IMAGES# if you want to. -

AdhemPlease "Preview" your future posts. Your formatting is awful. Especially learn to use the [ code ] tags.
Are you sure DateTime.Now.ToString() returns a string in the format of 'MM/DD/YYYY HH:MI:SS.FF3'?
Fix that and if you still having the problems, debug the actual result of your string.Format() and post that. -
How to open a file form a blob column?
I'm storing some files in oracle 9.2 in a blob column, although i can't open them using php 4, I'm using this script :
<?php
$SQL="SELECT ID_ARCHIVO,CONTENT";
$SQL=$SQL." FROM ARCHIVOS_PRUEBAS ";
$SQL=$SQL." WHERE ID_ARCHIVO =".$v_ID_ARCHIVO ;
$c=OCILogon("$v_USER" , "$v_PASS" ,"$v_CONEXION" );
$s = OCIParse($c,$SQL );
if (!OCIExecute($s)) { print "execution failed"; exit(); }
OCIFetchInto($s,&$arr,OCI_RETURN_LOBS);
echo $arr["CONTENT"]->load();
?>
it shows this error
Fatal error: Call to a member function on a non-object in ov_archivo_detail_test.php on [echo $arr["CONTENT"]->load(); ].
I know the data is stored correctly since i used toad to save and open the blob file and it was ok, but i still can't find a right way to show the file from the web.
