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
Stewart

RESTful Service Module and Blob column

Hi
I created Restful as GET with some parameters. Everythink works without blob column. When I run restful handler in blob column i had "...binary data omitted...". Is some solution to catch file from APEX web service ?

Hi,
You cannot use Blobs directly as fields in CMP EJB, since Blob is really an open cursor to the database, and it is not serializable.
Here's a How-to on using Blobs

You can see the code for this at the end of the page

Out of Order Primary Keys and Blob fields

Hi,
I am using Oracle Migration Workbench to transfer the data from SQLServer 2000 to ORacle 9i. I am running into the following issues and was wondering if you had any ideas what may be going on:
1.) Primary keys are out of order
2.) Blob fields are inserted into the incorrect row
Ex. BLOB field stating 'Application active' should be associated with Act_key (primary key) = 5 and it ends up transfering over with act_key 28.
Thank you for any information you may have on this.

I am very interested in this thread because I have encountered a similar problem with BLOB columns, except that I am also seeing this with CLOB's.
Essentially the all the data gets 'migrated', but the CLOB and BLOB columns are all mixed up!
Any solutions?

Search a text in a multiple tables and one table has BLOB column

Hi,
I couldn't find a solution/examples for below scenario in oracle text documentation or related forums.
I need to search a text in a multiple tables,in that one table has blob column which is used to store the documnents(pdf,doc,jpg..etc) and other tables have varchar2 columns,These tables have realation each other.
Please provide a sample examples for above scenario.
Thanks in advance..

Have a look at my blog entry here:

How to read a XML file from BLOB column and insert in a table - PL/SQL Only

Hi,
To make data load more simple to end user instead placing file on the server and use SQL-LOADER, I came up with new idea that using oracle ebusiness suite attachment functionality. that loads a XML file from local PC to a database column(table is fnd_attachments, default data type is BLOB over here).
I tried with DBMS_LOB and didnt get around.
Please can anyone tell me how to read the BLOB column using PL/SQL and store the data in a oracle table. Here's the sample XML file and table structure FYI.

APEX- How to open world document (and other files) stored in a blob column?

Hi,
I have an application developed in Oracle Apex 3.2.1 and RDBMS Oracle 9.2.0.8 (SUN SOLARIS SPARC 64 BITS).
I have a table called BAC_ARQUIVO, with the following structure:
CREATE TABLE BAC_ARQUIVO
(NAME VARCHAR2(4000), /* Name of the file stored in BLOB column */
SUBJECT VARCHAR2(4000), /* A brief description about this file stored */
ID NUMBER, /* An identification of this file - It´s a PK column of this table*/
BLOB_CONTENT BLOB, /* Blob field that store diferent kind of files - XLS, DOC, PPT, PDF, EXE, ZIP, etc);
MIME_TYPE VARCHAR2(4000) /* Identification about which kind of file is stored on BLOB field */
The field BLOB_CONTENT of this table can store:
- Executable files;
- MS-World Documents (DOC);
- Zip Files (ZIP);
- Ms-Excel Files (XLS);
- Ms-Powerpoint files (PPT);
- Adobe documents (PDF);
Actually, in this APEX application, i have developed a interactive Report in which the user can download these files to desktop without problems.
But now, my user would like to know if it´s possible that APEX application can OPEN some of these files stored on this BLOB column WITHOUT download it.
My user would like to see a hiperlink (or button) that, if pressed/acessed, can open a new page (or a page inside application) with the document. He doesn´t need to edit this oppened file. He only wants to see it.
For example, if the file stored in the blob column is ms-word type , so the application will open a MS-WINDOWS application with these file.
Is it possible?
I saw in this forum that it´s possible to open a file stored on "/i/" directory, but i need to open the file stored in BLOB column. I don´t want to store the file in operational system of the server.
Could any one demonstrate to me how it could be done?
Best regards,
Sergio Coutinho

Hi Sergio,
This link might be helpful:
http://www.oracle.com/webfolder/technetwork/tutorials/obe/db/apex/r31/apex31nf/apex31blob.htm
Also refer the BLOB Download Format Mask :
{message:id=9716335}
Here I have given the format mask for APEX 4.0, which will slightly differ for 3.2.1 and proposed changes
in the format mask are:
1) Format Mask: DOWNLOAD
2) Content Disposition: Inline
This will be achieved with it:

Reading and Writing to blob column is very slow

Hi
I want to write a serialized java object called 'engine' to a database table called javaObjectsDB. The serialized object could be of sizes anywhere between 20MB to 4GB. I am using the following code to write this 'engine' object
               * Write java object to BLOB in DB - Start
               Connection conn=null;
               conn = Util.getConnectionFromDS();
          PreparedStatement ps=null;
          String sql=null;
               Engine.startWatch();
               ByteArrayOutputStream baos = new ByteArrayOutputStream();
               Engine.endWatch("Time for ByteArrayOutputStream");
               Engine.startWatch();
               ObjectOutputStream oos = new ObjectOutputStream(baos);
               Engine.endWatch("Time for ObjectOutputStream");
               Engine.startWatch();
               oos.writeObject(this.engine_);
               Engine.endWatch("Time for oos.writeObject");
               oos.flush();
               Engine.startWatch();
               byte[] data = baos.toByteArray(); // in case of using ByteArrayOutputStream
               Engine.endWatch("Time for toByteArray");
               Engine.startWatch();
     sql="insert into javaObjectsDB values (?)";
     ps=conn.prepareStatement(sql);
     ps.setObject(1, data); // in case of using ByteArrayOutputStream
     ps.executeUpdate();
     Engine.endWatch("Time for prepare statement and insert");
               * Write java object to BLOB in DB - End
To read from database BLOB column back to the engine object I use the following code:
try {
               String readBlob = "SELECT javaObject FROM javaObjectsDB ";
               Statement readBlobStmt = conn.createStatement();
               ResultSet resultSet = readBlobStmt.executeQuery(readBlob);
               while (resultSet.next()) {
                    * ByteArrayStream *** Start
                    Engine.startWatch();
                    Blob blob = resultSet.getBlob(1);
                    Engine.endWatch("loadPlan::Time for getBlob");
                    Engine.startWatch();
                    byte [] data = blob.getBytes(1,(int)blob.length());
                    Engine.endWatch("loadPlan::Time for getBytes");
                    Engine.startWatch();
               ByteArrayInputStream bais = new ByteArrayInputStream(data);
               Engine.endWatch("loadPlan::Time for ByteArrayInputStream");
               Engine.startWatch();
               ObjectInputStream oin = new ObjectInputStream(bais);
               Engine.endWatch("loadPlan::Time for ObjectInputStream");
               Engine.startWatch();
               engine_ = (Engine)oin.readObject();
               Engine.endWatch("loadPlan::Time for oin.readObject");
               System.out.println("engine object prepared");
                    * ByteArrayStream *** End
               } //while of result Set
The time taken to write and read for a engine object of size 124MB are:
write - 41secs
read - 28secs
For a engine object of size 340MB
write - 3minutes
read - 1minute
This is a lot of time for such small object size, and since we are expecting sizes of 4GB, I need to have better performance. Please suggest what I can do to improve performance for read and write.
One thing I tried was using cached lobs but not of much use.

Insert picture in a blob column and show in oracle forms

hi ,
please help me with this
I am trying to insert a picture into a blob column of a table and show that in oracle forms , but not able to do it .
I am using version 10g for both database and forms .
Please tell me how to insert a picture in a blob column that is stored in my 'c:\test' folder
and also how to show that in forms .

To populate the Image Item you have to use the Webutil Client_Read_Image_File() built-in.
here
http://www.oracle.com/webapps/online-help/forms/10g/state?navSetId=_&navId=3&vtTopicFile=f1_help/builtn_r/readimag.html&vtTopicId=
To add an Image Item to your block based on the table that contains the BLOB column, then give this Image Item the BLOB column name.
So that, all you have to do is to execute query on that block.

Delete blob column in source and rename schema using rule

Hi
I have blob column in source table, which i am deleting while capturing through rule based tranformation and also renaming the schema through the same rule.
SET SERVEROUTPUT ON
DECLARE
v_dml_rule VARCHAR2(80);
v_ddl_rule VARCHAR2(80);
BEGIN
DBMS_STREAMS_ADM.ADD_TABLE_RULES(
table_name => 'ENGINE.ACTIVATIONS',
streams_type => 'CAPTURE',
streams_name => 'CAPTURE_TO_&destsid',
queue_name => '&source_strmadmin_user..&sourcesid._TO_&destsid',
include_dml => true,
include_ddl => false,
include_tagged_lcr => false,
source_database => 'MMSTG.DEMOWORLD.COM',
dml_rule_name => v_dml_rule,
ddl_rule_name => v_ddl_rule,
and_condition => ':lcr.get_command_type() != ''DELETE''',
inclusion_rule => true);
DBMS_STREAMS_ADM.DELETE_COLUMN(
rule_name => v_dml_rule,
table_name => 'ENGINE.ACTIVATIOINS',
column_name => 'INSTANCE_DATA',
value_type => '*',
step_number => 0,
operation => 'ADD');
DBMS_STREAMS_ADM.RENAME_SCHEMA(
rule_name => v_dml_rule,
from_schema_name => 'ENGINE',
to_schema_name => 'ENGINE_WEST',
step_number => 0,
operation => 'ADD');
DBMS_OUTPUT.PUT_LINE('Capture DML Rule for ENGINE.ACTIVATIOINS => ' || v_dml_rule);
END;
I use step_number 0 for both rename schema and delete column. Some how, delete column transformation is not firing and it replicates the blob column with some bytes instead of zero bytes.
How do we execute this both rule based transformation with correct step_number to fire both transformations. Please do let me know..
Thanks
Bala

In what version?
Step 0 is the default so that is not the issue.
Can you also post the DDL for your table and the results of the following query:
SELECT *
FROM dba_streams_unsupported
WHERE owner = <schema owner>
AND table_name = <your table name>;

Loading PDF and Video Files in BLOB Column

Hi,
Below is my database version
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - 64bit Production
The Requirment is
In a web page ( developed using Java Spring ) end user has the funtionality to upload a pdf/video file by browse the required file from his/her local computer.
Once the webuser clicks the SAVE button then the selected file needs to be inserted in Oracle BLOB column.
Front end needs to call an Oracle Package to achive this.
Please suggest me how to create oracle code(Procedure) for this?
Thanks in advance.

Karthik.K

Check BFILENAME + DBMS_LOB. Something like:
DECLARE
    v_file BFILE;
    v_blob BLOB;
    v_size NUMBER;
BEGIN
    v_file := BFILENAME(<ORACLE DIR OBJECT POINTING TO OS DIR WHERE FILE RESIDES>,<FILE NAME>);
    DBMS_LOB.OPEN (v_file, DBMS_LOB.lob_readonly); --Read the file
    DBMS_LOB.createtemporary(v_blob,TRUE);
    v_size := DBMS_LOB.getlength(v_file);
    DBMS_LOB.loadfromfile(v_blob,v_file,v_size);
END;

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

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 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();

Associative array type for each blob column in the table

i am using the code in given link
http://www.oracle.com/technology/oramag/oracle/07-jan/o17odp.html
i chnages that code like this
CREATE TABLE JOBS
JOB_ID VARCHAR2(10 BYTE),
JOB_TITLE VARCHAR2(35 BYTE),
MIN_SALARY NUMBER(6),
MAX_SALARY NUMBER(6),
JOBPIC BLOB
CREATE OR REPLACE PACKAGE associative_array
AS
-- define an associative array type for each column in the jobs table
TYPE t_job_id IS TABLE OF jobs.job_id%TYPE
INDEX BY PLS_INTEGER;
TYPE t_job_title IS TABLE OF jobs.job_title%TYPE
INDEX BY PLS_INTEGER;
TYPE t_min_salary IS TABLE OF jobs.min_salary%TYPE
INDEX BY PLS_INTEGER;
TYPE t_max_salary IS TABLE OF jobs.max_salary%TYPE
INDEX BY PLS_INTEGER;
TYPE t_jobpic IS TABLE OF jobs.jobpic%TYPE
INDEX BY PLS_INTEGER;
-- define the procedure that will perform the array insert

END associative_array;
CREATE OR REPLACE package body SHC_OLD.associative_array as

) is
begin
forall i in p_job_id.first..p_job_id.last
insert into jobs (job_id,
job_title,
min_salary,
max_salary,
JOBPIC
values (p_job_id(i),
p_job_title(i),
p_min_salary(i),
p_max_salary(i),
P_JOBPIC(i)
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 -
http://jes.blogs.shellprompt.net/2007/05/18/apex-delivering-pages-in-3-seconds-or-less/
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.

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.
http://www.oracle.com/technology/products/database/application_express/pdf/apex_text_application_v1.6.pdf
If you can help me with this I'd really appreciate it.
Thanks again.
