• How to select the csv data stored in a BLOB column as if it were an external table?

  Hi all

  (Happy to be back after a while! )

  Currently I am working on a site where users should be able to load the data of csv (comma is the separator) of their client machines (APEX 3.2 application) in the Oracle 11.2.0.4.0 EE database.

  My problem is:

  I can't use an external table (for the first time in my life ) so I'm a little clueless what to do as the csv data is stored by the application of the APEX in a BLOB column, and I'm looking for an elegant way (at least SQL PL/SQL/maximization) to insert the data into the destination table (run validations by a MERGER would be the most effective way to do the job).

  I found a few examples, but I think they are too heavy and there could be a more elegant way in Oracle DB 11.2.

  Simple unit test:

  drop table CBC purge;

  drop table dst serving;

  create table src

  (myblob blob

  );

  create table dst

  (num number

  , varchar2 (6) str

  );

  Insert in src

  Select utl_raw.cast_to_raw (1; AAAAAA ;'|| Chr (10) |

  2; BATH; »

  )

  Double;

  Desired (of course) output based on the data in table SRC:

  SQL > select * DST;

  NUM STR

  ---------- ------

  1 ABDELKRIM

  2 BATH

  Does anybody know a solution for this?

  Any ideas/pointers/links/examples are welcome!

  / * WARNING: I was 'off' for about 3 months, then the Oracle - the part of my brain has become a bit "rusty and I feel it should not be so complicated as the examples I've found sofar ' * /"

  Haha, wonder about regexp is like the blind leading the blind!

  However, it's my mistake: I forgot to put the starting position setting (so 1, 2, 3,... was in fact the starting position, not the nth occurrence. duh!)

  So, it should actually be:

  select x.*
  ,      regexp_substr(x.col1, '[^;]+', 1, 1)
  ,      regexp_substr(x.col1, '[^;]+', 1, 2)
  ,      regexp_substr(x.col1, '[^;]+', 1, 3)
  ,      regexp_substr(x.col1, '[^;]+', 1, 4)
  ,      regexp_substr(x.col1, '[^;]+', 1, 5)
  ,      regexp_substr(x.col1, '[^;]+', 1, 6)
  from  src
  ,      xmltable('/a/b'
                passing xmltype(''||replace(conv_to_clob(src.myblob), chr(10), '')||'')
                columns
                  col1 varchar2(100) path '.') x;
  

  Note: that's assuming that all the "columns" passed in the string won't be lame.

  If one of them might be null, then:

  select x.*
  ,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 1)
  ,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 2)
  ,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 3)
  ,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 4)
  ,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 5)
  ,      regexp_substr(ltrim(x.col1, ';'), '[^;]+', 1, 6)
  from   src
  ,      xmltable('/a/b'
                passing xmltype(replace(';'||replace(conv_to_clob(src.myblob), chr(10), ';')||'', ';;', '; ;'))

• 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)

• Prepare a document to insert a row that contains the Blob column. Is what sense this correct?

  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?

  2 Preparestatement.setBlob(parameter number, inputstream type object)

  1 Preparestatement.setBlob(parameter number, blob type object)

  2 Preparestatement.setBlob(parameter number, inputstream type object)

  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.

• Classic report SQL with BLOB column not refreshing with jQuery Trigger Apexrefresh call

  Hello

  Really hoping that someone can help me, but for some reason that I try to report updated in dynamic Action to help:

  jQuery('#my-report').trigger('apexrefresh');

  on a simple SQL query report classic. I have used this many times on other parts of the report but the only difference with the report region where it is not refreshing, is that the table contains a BLOB column as it is essentially a report of downloaded files that users have made to the page by using the file browse.

  Would really appreciate help with that basically, I don't want to perform a full page refresh, because it currently operates.

  It has to do with the fact that this report is the question about a BLOB column, which is a link to the uploaded file?

  Thank you.

• Update a BLOB column

  Hello

  I have Oracle XE 11.2.0 loaded on a Windows Server.  It works very well.  I use Apex 4.1 on break as well.

  In a table, I have a column (LIST_FILE) that contains the name of a file and does not include the file extension.  Recently, I added a BLOB (LIST_PDF) column to this table.

  I would like to create SQL to update each row of this table by inserting PDF file into the blob.  For each row in the table, there is a file beginning with value in LIST_FILE and followed by a period and PDF (.) (PDF).  File1.PDF, File2, PDF, etc.  The windows directory that contains the PDF files can be moved anywhere on the windows server.

  How to build the SQL to update the BLOB column?

  Thanks for your help.

• How to make the image Inline source to read from database BLOB column?

  Dear all

  I have a database table that contains the BLOB column. And tif files in the BLOB column.

  Now, I want to display the value of the BLOB file in af:inlineFrame.

  I want to do this because I installed "AlternateTiff" on my browser to view tif files in the browser.

  You can download it from http://www.alternatiff.com/

  The inLine frame component has a property called 'Source '. The value of the "Source" property must be the location of the URI of the content you want to display in the example of frame.for online:

                        <f:facet name="second">
                              <af:inlineFrame id="if2" styleClass="AFStretchWidth"
                                              shortDesc="To browse the selected document" source="/temp/myFile.tif"/>
  

  now, I want to change this example to read the content of the BLOB column.

  IS this possible?

  Thanks in advance

  You must install a servlet which reads the data from the BLOB and represents the data structure.  My blog http://wp.me/pcBZk-bU shoes how to proceed.

• Creating INDEX on a BLOB column in a separate tablespace

  Hello

  
  

  Our database contains 2 storage spaces :

  -Tablespace DATA : is reserved to hold the data.

  -Tablespace INDX: is reserved to hold the index.

  
  

  For some reason, that we must create the indexes on columns of type blob and the pending order are:

  SQL > CREATE INDEX my_index ON DOC_CONTENTS (doc_content) INDEXTYPE IS CTXSYS. CONTEXT;  / / doc_content a blob type.

  SQL> index created
  

  Now, all indexes are created in the tablespace for DATA that is not good, they should be created in the tablespace INDX (now is empty)

  For this reason, and after a search, I specified the tablespace INDX , which will contain the index, and the used command is:
  

  SQL > CREATE INDEX my_index ON DOC_CONTENTS (doc_content) INDEXTYPE IS CTXSYS. CONTEXT TABLESPACE INDX;

  *

  ERROR on line 1:

  ORA-29850: invalid option for creating domain index

  NB: also, when I try to use the same command with varchar column, it works.

  SQL > CREATE INDEX my_index ON DOC_CONTENTS (doc_name) TABLESPACE INDX;  / / doc_content a type VARCHAR2.

  SQL> index created

  
  

  Do you have an idea on how to create indexes on a blob column in a different tablespace?

  This question has nothing to do with the Oracle objects, but is related to Oracle Text, then perhaps that some moderator moves text objects.

  To specify a storage space for a ctxsys.context Oracle Text index domain index tables, you must create a storage preference, specify storage spaces in attributes of this preference, then use this preference in settings of creating index.  Please see the example below which shows first create domain index tables in the default users tablespace, then the creation of the field tables to be indexed in the example tablespace.

• 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

  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
