• Download the Blob file

  I use ADF BC, Jdeveloper11g 1.1.1.4
  
  in my application, I need the list down all the files stored in the Blob from a database table field in the af: table, if the user clicks on the name of the file that is linked to af:link, then the file will be opened to show the user the contents of the file.
  
  There is a sample built in 10g of http://technology.amis.nl/blog/category/oracle/adf-jheadstart, but only limited to types of files as 'doc', 'pdf', 'excel '.
  
  I think there is a solution put forward 11 g and also not be limited only these three types of file upload & dwonload to & database right of files?
  
  Could you expert give me only a sample built in 11g to let me study, thank you very much!

• Download the BLOB table

  Hello
  
  How can I download BLOB table. On my page, I use a table with a row displaying the name of the file and I put the af:commandlink type. It is possible with af:fileDownloadListener?

  Hello

  In your table, add a new column

  You supporting bean (myBean) add this method and replace my your values (name, attribute name iterator)

    public void downloadFileAction(FacesContext ctx, OutputStream out) {
  
        ExternalContext ectx = ctx.getExternalContext();
        Row currentRow = ADFUtils.findIterator("MyIterator").getCurrentRow();
        String fileName = (String)currentRow.getAttribute("FileName");
        BlobDomain content =  (BlobDomain)currentRow.getAttribute("FileContent");
        Long length = content.getLength();
  
        HttpServletResponse response = (HttpServletResponse)ectx.getResponse();
        response.setHeader("Content-Disposition", "attachment;filename=\"" + fileName + "\"");
        response.setContentLength(length.intValue());
        try {
            InputStream in = content.getBinaryStream();
            byte[] buf = new byte[1024];
            int count;
            while ((count = in.read(buf)) >= 0) {
                out.write(buf, 0, count);
            }
            in.close();
            out.flush();
            out.close();
            ctx.responseComplete();
         } catch (IOException ex) {

• Manually download the blob file in apex

  Hello

  
  Currently, I load csv files in a table via an apex user interface. The table that contains the data is constructed as follows:

  TBL_UPLOADS

  (

  ID NOT NULL

  BLOB_CONTENT BLOB

  MIME_TYPE VARCHAR2 (255)

  NAME VARCHAR2 (255)

  LAST_UPDATED DATE

  CHARACTER_SET VARCHAR2 (128)

  )

  I have an automatic line (DML) process that defines the operations allowed on the table. In my case, it's only "insert." I also mentioned here a condition that the process runs only when you press the UPLOAD button. I also filled all the attributes of source as Element containing primary key column value (required) etc.

  I also have a DOWNLOAD button. In the section Action when the button clicked on this button the following applies:

  Action: SEND the PAGE

  Run validations: YES
  Action of the databases: ACTION of INSERT SQL

  It all works just fine. I just want the action to the database manually because I want to do more things then just insert. First thing I need to do is to replicate. It is where I am confused. Now I know I need to use a dynamic action for this. I don't know how to insert values into my tbl_uploads (the query insert himself). I looked at examples such as Denes Kubicek - ApEx Solutions , but I do not use the wwv_flow_files table. On the other hand, looks like a history of chickens and eggs for me because I need to insert data in my table (uploads) first.

  
  Can someone put back me on track?

  You can have multiple processes that have the same State (same IE "when button pressed")

  Thus, when BUTTON_X is pressed, all the processes that meet the condition will run accordingly.

  On this particular page, the first process is the Excel2Collection plugin.  This loads the data in a Collection of the APEX.

  The next process uses a PL/SQL code that transforms and loads data in the actual table.

  The two processes have the Condition "when button pressed" defined on the same button. (P19_UPLOAD)

  MK

  (I don't like the view of 'the tree')

  

  Details of the process ' file in the Collection ': ('Collection of process' process is identical)

• Download the BLOB form

  I have a form with a BLOB column. The column is set to "Browse file". In the value of the source or the expression of the column, it is on:
  
  'STUDENT_DOCUMENT:attachment:Download '.
  
  After loading the data and view the page, the 'Download' link poster. I can upload most file types, but when I try to download a word doc, it does not work. I see this in the download dialog box
  
  'Type - unknown file type '.
  
  I checked the mimtype in the DB and it has the value "application/msword".

  Have you thought about trying to add the mime_type column in the format for the field of file mask?

• Download the content of the BLOB from a custom table

  In our application hosted the apex, the following code from the Express on the Application Developer's Guide works great to allow a user to download the contents of the blob of one of our paintings customized via a download button. However, the code does not work on the Cloud Oracle because the 'owa_util' package is no longer available. The code is as follows:
  
  CREATE OR REPLACE PROCEDURE download_my_file (p_file in number) AS
  v_mime VARCHAR2 (48);
  V_LENGTH NUMBER;
  v_file_name VARCHAR2 (2000);
  Lob_loc BLOB;
  BEGIN
  Name of SELECT MIME_TYPE, BLOB_CONTENT, DBMS_LOB. GETLENGTH (blob_content)
  IN lob_loc, v_file_name, v_mime, v_length
  OF file_subjects
  WHERE id = p_file;
  --
  -set up the HTTP header
  --
  -Use a NVL around the mime type and
  -If it is null it the value application/octect
  -application/octect can initiate a download of windows window
  owa_util.mime_header (nvl(v_mime,'application/octet'), FALSE);
  
  -set the size so that the browser knows how to download
  HTP.p ("Content-length: ' |") v_length);
  -the name of the file will be used by the browser if users only one save as
  HTP.p ('Content-Disposition: attachment; filename = "" | ") Replace (Replace (substr (v_file_name, InStr(v_file_name,'/') + 1), Chr (10), null), Chr (13), null). '"');
  -close the headers
  owa_util.http_header_close;
  -Download the BLOB
  wpg_docload.download_file (Lob_loc);
  end download_my_file;
  /
  
  In addition to the use of web services, does anyone know how to do this? Is it possible to add access to the package 'owa_util' in the cloud? I also tried apex_util.get_blob_file_src but that is also not available in the Oracle cloud.
  
  Thank you
  
  Steve

  Hi Steve,.

  (1) sys.owa_util is certainly available. You should be able to issue this block very well SQL commands:

  Start
  owa_util.print_cgi_env;
  end;

  ((2) I think the problem is that you have created a procedure that a) cannot not be granted run to the PUBLIC and b) cannot be called directly from the URL (because of a properly locked APEX listener which restricts entry points, i.e..) What procedures can be called directly from the URL).

  Even if there was no prohibition of granting something to the PUBLIC, you would never get by the restriction on the call of your own point of entry of the URL. Also in a facility non - Cloud APEX (and even when you're using mod_plsql), the list of entry points is applied through the PlsqlRequestValidationFunction (http://docs.oracle.com/cd/E23943_01/web.1111/e10144/under_mods.htm#HSADM698).

  Two ways around this:

  (1) you can define a request of the process which, when called, downloads the requested file

  or

  (2) you may want to expose this functionality via a RESTful Service of media resources, even though right now, I'm not necessarily details how you would ensure access to it.

  I hope this helps.

• Download the procedure not found on the server.

  Hello
  
  I created a feature to download files using the Oracle (http://download.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/up_dn_files.htm#CIHBFCDH) tutorial. The files are copied from the flow table in a custom table named SR_ATTACHMENTS with the following structure:
  
  Default primary key Type Nullable data column name
  IMAGE_ID NUMBER - 1
  NAME VARCHAR2 (60) Yes.
  Filename VARCHAR2 (60) Yes.
  Mime_type VARCHAR2 (60) Yes.
  DOC_SIZE NUMBER Yes-
  CREATED_BY VARCHAR2 (255) Yes.
  DATE of CREATED_ON Yes-
  Content_type VARCHAR2 (60) Yes.
  BLOB BLOB_CONTENT Yes-
  REQ_ID NUMBER Yes-
  
  
  There is a file record in the SR_ATTACHMENTS table:

• Not able to see the contents of the BLOB download link in report object

  Hello
  
  I have a report on a table, the columns of this table is of type blob.
  
  In the report of the blob column is showing.

  [datatype]

  I wanted a link by which we will be able to d/l the blob file.
  When I check the column to blob column attributes, I don't see "Content BLOB" download under number/Date Format link.
  We have Apex 4.1.1
  
  Should I change something, so that we can see "Content BLOB" download link?
  
  Thank you.

  Machan wrote:
  I tried. It just displays the length (integer).
  I don't always get the link!

  What is the value of the attribute Display as ?

  What happens if you enter a BLOB format directly mask as in the example in the docs:

  DOWNLOAD:EMP:RESUME:EMPNO::RESUME_MIMETYPE:RESUME_FILENAME:RESUME_LAST_UPDATE::attachment:Resume

• After downloading 4.0 I get this message: application JavaScript is unable to create the plugin object of mcafee: TypeError: components.classes['@ [cid] is undefined
