• Deleting the BLOB file by users

  My application displays BLOB files. How / what steps should I follow to allow users to delete the BLOB file themselves? I use interactive report to view the files and giving the download option that works very well. I need to provide the option for the user to delete the file as well but am stuck on this for a while now. Please help me.

  Thank you

  Deletion and modification functionality, you need are already present in page 4 via the process of FRA and ARP generated by the wizard. You did not just providing a link to the page that passes the value of the ID of existing lines.

  See copy app 38544. I added a link to the column of the report on page 6 that passes the ID of the line on page 4. Details of the selected file are displayed, and it is possible to replace the BLOB content using the browse file or set the line removed using the delete key.

  Alternatively, you can add a checkbox column to the report on page 6 using the apex_item.checkbox2 method of the API, a delete button to submit the page and a process of page after submit PL/SQL it to remove the saved files.

• compress the blob column to save space on the server

  Hi friends,

  I have a problem with the blob column, in the oracle 11.2.0.4 on aix Server database

  I have a table with a blob of column (containing a jpg file). This table is in a tablespace of 300 GB and storage space is full. There is no space on the server (asm).

  I need to load the jpg more in this table, but there is no space.

  I've read a few articles on tha compress blob type column, but I'm not sure what I should do.

  Is it possible to compress the blob column without going to a different tablespace (because the server has no more space to create a new one).

  The table and column have been created in a traditional way.

  Please, advice?

  Best regards

  Dbape.

  But this method requires add-on EA "Adv. Compression" ($$$).

  OP he wanted to compress .jpg files.

  BUDOKAI

  It is not possible.

  the .jpg files are already compressed.

  IIRC (of my Compression Adv. test) - SecureFile "knows best" and will not try to compress BLOBs identified as JPGs or any other known formats of files (such as .zip files)

  In other words - SecureFile is not the OP no good for the type of data, it is try to compress them.

  Are the only solutions that the OP has to enable it to store more JPG images

  • get rid of the old pictures
  • Add more disks
  • resize images (ordimage)
  • recompress the image by reducing the quality as long as the resulting image is unusable (ordimage)

  When we prepare the statement to insert a row that contains the Blob column. Is what sense this correct? And what is the difference? Does anyone know?

  I answered in your other thread and provided a link to the JDBC Dev Guide section, which explains how to work with type LOB and BFILE data.

  Have you read this article from doc?

  Did you read my response to your other thread?

  In java, a BLOB is just the index that gives you access to the content. In your case, you access by selecting a locator BLOB existing and getting his inputstream. This inputstream is what allows you to access the content real blob.

  The Locator is just that; It specifies the LOCATION of the blob content, but NOT the content.

• Stored in the BLOB column display PDF problem

  Hello everyone.
  
  I tried to follow this tutorial http://asktom.oracle.com/pls/asktom/f?p=100:11:0:p11_question_id:232814159006 on the display of PDF files stored in BLOB columns. This is done on Apex 4.2, with my DB 11 g running. I have my procedure, which I will post below:
  

  create or replace procedure "PDF" (p_id IN gvo_documents.doc_id%type)
  is
      l_lob    blob;
      l_amt    number default 30;
      l_off   number default 1;
      l_raw   raw(4096);
  begin
      select contents into l_lob
          from gvo_documents 
           where doc_id = p_id;
  
   -- make sure to change this for your type!
      owa_util.mime_header( 'application/pdf' );
  
  
      begin
          loop
            dbms_lob.read( l_lob, l_amt, l_off, l_raw );
            htp.prn( utl_raw.cast_to_varchar2( l_raw ) );
            l_off := l_off+l_amt;
            l_amt := 4096;            
      end loop;
          exception
             when no_data_found then 
                NULL;
          end;
  
  end;
  

  I am trying to run this through a region dynamic PL/SQL, and even if I don't get any error, the content displayed is a huge mess of truncated text and strange characters. I tried to run this procedure on many other types of documents, including word and jpeg image files, all with the necessary changes in my inside, and regardless of what I use, I always get a big mess of strange characters. Does anyone have information or ideas why this is happening?

  If I understand correctly, your needs must be broken down into two problems:
  1) click the link that opens a window showing a new APEX page
  (2) an APEX page displays the document, download it not.

  I did not (yet) #1.
  However, you can generate a URL that points to the new page in the select for the report.

  It's a related issue, but no response yet:
  Open the pdf file in the browser window

  The key is to target = "_blank" to the anchor tag.
  To generate the URL, you must use the APEX_UTIL.prepare_URL () function.

  If this does not work, a dynamic Action that makes magical things of JavaScript may be necessary.

  # 2, I lost the URL that showed how to display a PDF file in a page "form.
  From what I remember:
  Start with a blank page with a pristine area of HTML (all items will in the HTML area)
  Add an element to the PK/annual
  part I forgot Create a Data Manipulation process
  -Automated row Fetch
  -By loading - after the header
  -(stuff for your table/view)
  part I forgot Create a (I think) "File browser" item type. For the parameters:
  -Storage of Type "BLOB column specified in the Source element" (and put the name of the BLOB column)
  -MIME Type column: (column name) - since there are several types, this is a MUST HAVE
  -Filename column: (column name) - I highly recommend you have this.
  -Provision of content is INLINE<-- this="" is="" the="">

  In addition, you will need a browser for each of the Types MIME Plugin (if not, the browser may try to "Download" the file)
  Browsers can manage the types of images internally. Plugin Adobe can handle PDF files. I do not know Word/Excel.

  Yet once again, I don't remember the exact details, but that should cover most of it.

• Interactive report will not save the BLOB column attributes

  I created several interactive reports with the 4.0 and 4.1 which had columns of type BLOB with no problems and the download link worked fine. After 4.2 update, interactive reports get the following error when you click on the download link:
  Not found
  The requested URL /apex/apex_util.get_blob was not found on this server
  
  If I open the edit page of the report, the BLOB downloads very well. When I looked at the report in detail the attributes of the BLOB column, I noticed that the BLOB column attributes had not been met. I tried several times to fill in (name of the Table column name, Primary Key, MIMETYPE, etc), but after applying changes and reopen the attributes page for the blob column, the values, that I entered is not saved.
  For completeness, here is the select statement for the report:
  Select "DESC_ATT_ID."
  "BR_ID,"
  "FILENAME."
  "MIME TYPE"
  DBMS_LOB. GetLength ("DESC_ATTACHMENT") 'DESC_ATTACHMENT '.
  of ' #OWNER # '. " ALTEC_BR_DESC_ATT ".
  WHERE BR_ID =: P3_BR_ID
  
  Also, here is the value for the number/Date of the BLOB column format:
  DOWNLOAD: ALTEC_BR_DESC_ATT:DESC_ATTACHMENT:DESC_ATT_ID
  
  Can someone tell me please in the right direction to get the link to the interactive report work correctly?
  Thank you very much

  Hello
  How about you, you do not format BLOB column, do you it manually like this example here:

  Apex. Oracle.com
  workspace: somefeto
  user: test
  PWD: test
  Application 63066

  in the same workspace, there is Sample File Upload and Download (App ID 10540), and it works very well...

  If not, Pls, reproduce the problem on apex.oracle.com

• How to stop the blob column don't affect display performance.

  Hello
  I have an external table that has a blob column. The table has at present about 40 recordings that the blob column is reading in some 150 MB total records. When I try to view the external table performance is terrible, takes to always display the table. I thought far around from this would be to create a view that would leave the blob column, in an attempt to show folders quickly, but it has no impact on performance.
  
  Is it possible to create the view that returns the columns I want quickly for these 40 weird files?

  You can try to create 2 external tables out of this file, without the BLOB column and another containing the BLOB column.

  Then query the external table BLOBless when you have no need for the BLOB.

  Charrier,

  If you form the string yourself, you can use the function utl_raw.cast_to_raw on your channel.

  http://download.Oracle.com/docs/CD/B12037_01/AppDev.101/b10802/u_raw.htm#997086

  Hi Yang,

  Oracle recommends the setting of the 'get_lob_precision' false flag to avoid this error.

  For this,.

  1. make a backup of your ODIPARAM. BAT file.
  2. open ODIPARAM. BAT file and add the following line.

  Set ODI_ADDITIONAL_JAVA_OPTIONS = % ODI_ADDITIONAL_JAVA_OPTIONS % ""-Doracledatabasemetadata.get_lob_precision = false ' "

  Next to

  Set ODI_ADDITIONAL_JAVA_OPTIONS = ""-Djava.security.policy = server.policy ' "

  PS:If, the parameter is defined, the result "ODI_ADDITIONAL_JAVA_OPTIONS" ("SNP_ADDITIONAL_JAVA_OPTIONS" or "SNP_JAVA_OPTIONS") should be similar to the foregoing.

  Restart the ODI and try.

  Thank you
