• Write the blob value in a file

  Hi all
  
  
  I'm looking on the correct method of writing a blob value to a file. I know the best way to use an external language. For example, Java or C. But also, I met a number of solutions to do within pl/SQL block. All of them look like this:
  
  
  CREATE OR REPLACE PROCEDURE Write_Binary_file
  (
  PC$ Directory IN VARCHAR2
  , PC$ file_name IN VARCHAR2
  , PC$ SQL_Order IN VARCHAR2
  , PB$ Raise IN DEFAULT BOOLEAN FALSE

  Dbms_Output.put_line(LC$MSG);
  RETURN;
  END;
  
  -Open the output file-
  LF$ FicOUT: = UTL_FILE. FOPEN (Directory$ PC, PC$ filename, 'W', 32764);
  
  -write the file-
  LOOP
  -play songs-
  Dbms_Lob.read (src_lob, amt, pos, buffer);
  -write the songs-

  Utl_File.fclose(LF$FicOut);

  But this code doesn't seem to work. The problem is that it always creates a slightly bigger than an initial file. So copy jpg will never be opened with any viewer.
  
  Can someone explain this problem and give no work around?
  
  Thank you

  Hello

  If I look at this procedure, I think that you forget to check if the last part, it takes to read is less than 32000. Now you put the always full buffer to the desired quantity. The last part, you only need to read from the BLOB what remains, nothing more. By reading more, get your blob of larger than expected.

  I use the package lie on this page for several years and no complains: http://www.adp-gmbh.ch/blog/2005/november/20.html

• Copy all the BLOBs from one table to another

  Hi all
  
  I hope that I put in the right place. I am trying to copy from one table to the other BLOBs, but were usuccessful. Here is the script that I wrote to do, but it just loaded a field saying not supported. Is there something I'm missing, I'm using the APEX 3.1.2.
  
  Thanks for your help.
  
  DECLARE
  number of v_id;
  v_document blob.
  v_filename varchar2 (200);
  v_mimetype varchar2 (200);
  
  
  
  CURSOR c_Document IS
  SELECT id, name of the document file, mimetype
  IN v_id, v_document, v_filename, v_mimetype
  
  OF CAB_APPEAL_ACTIONS
  WHEN THE DOCUMENT IS NOT NULL;
  
  BEGIN
  
  FOR r_Document in c_Document
  LOOP
  INSERT INTO CAB_APPEAL_DOCUMENTS
  (APPEAL_ACTION_ID,
  DOCUMENT,
  FILE NAME,
  MIMETYPE
  )
  VALUES
  (v_id,
  v_document,
  v_filename,
  v_mimetype
  );
  
  END LOOP;
  
  END;

  In addition, what is wrong with just...

  INSERT INTO CAB_APPEAL_DOCUMENTS (APPEAL_ACTION_ID,
                                    DOCUMENT,
                                    FILENAME,
                                    MIMETYPE)
     SELECT   id,
              document,
              filename,
              mimetype
       FROM   CAB_APPEAL_ACTIONS
      WHERE   DOCUMENT IS NOT NULL;
  

  APEX will end process page in a BEGIN block... END; block anyway.

• How to write the raw buffer grabber (table 2D) image to PC memory?

  Hello

  I use a library C++ and NIImaq to save table raw image 2D on PC.

  I have a PCI-1428 acquisition card.

  Now, I'm writing a 2D framebuffer grab table memory PC I assigned using virtualalloc.

  Any way to do it?

  Thank you

  Travis

  Hi Travis,

  After further research, I found that you can use the imgSessionCopyBuffer function (see the reference help function OR-IMAQ for more information) to transfer your data from the memory embedded in your designated PC buffer.

  Also, you can find more information on how to set up in the developer zone article below Acquisition ring (Versus the system of onboard memory section memory speak your specific question).

• How to write the suspicion on physical table

  Hi all
  
  That's what I read on the creation of index in the physical table
  
  http://download.Oracle.com/docs/CD/E12096_01/books/AdminTool/admintool_PhysicalSetup32.html#wp1054719
  
  The Index indicator tells the optimizer to scan a specified index, rather than a table. The following hypothetical example explains how you can use the Index indicator. You will find queries on the table ORDER_ITEMS is slow. See you the execution plan of the query optimizer and find that the FAST_INDEX index is not used. You create an indicator of Index to force the optimizer to scan the FAST_INDEX index rather than the table ORDER_ITEMS. The syntax of the indicator Index is index (table_name, index_name)...
  
  index (table_name, index_name)

• Write the spreadsheet in an array of strings on a different worksheet

  Hello

  is it possible to write the spreadsheet to a table of chains, but to an additional worksheet?

  I am writing the results of the spreadsheet, but I want to create a different worksheet so that I can put the raw data.

  is this possible?

  If so, how?

  

  You can't unless you start using ActiveX or report generation tool to connect with a real spreadsheet .xls file.

  You are read and write a text file in the form in the way of a spreadsheet with delimiters between values in a row and the lines of text on the other.  Text files have no understanding of the data being on a "sheet" and other data on another.  It is a peculiarity of the format property of Excel file (and thus other spreadsheets) that allows Excel what data need to be put on what spreadsheet.  It is not the kind of information that you can pass along the use of LabVIEW based text file i/o functions.

• How to write the xml content of a file (Blob data Type) with other columns in file system

  Team,
  We are currently working on oracle 11 g. Suppose that we consider the SCOTT. EMP table for our creation of the table.
  All existing columns of SCOTT along. EMP table allows to assume that this table has an additional column name emp_xml, which is of TYpe of BLOB data and it holds xml data.
  the size of the data blob for each record in this col is greater than 32 KB (normally about 1 GB), now I want to write the contents of this column along
  with enmae, empno, hiredate into an external file. Assume that if we are only to the BLOB column that is emp_xml then the code below works

  Start

  for c in (select emp_xml from your_table)

  loop

  dbms_xslprocessor.clob2file (emp_xml.getclobval (), 'YOUR_LOCATION', 'YOUR_DYNAMIC_FILENAME')
  end loop;
  end;

  but I want empno, enmae, hiredate with blob emp_xml written in the external file. Any assistance in this case welcome.

  Concerning

  max_linesize

  Maximum number of characters for each line, including the newline character, for this file (minimum 1, maximum value 32767). If not specified, Oracle provides a default value of 1024.

  Defines how much you can read or write to a single call. I have to loop through the clob object and I write a pieces of 1024. So there is no limit to how much she can write. Just test it, IT will WORK!

  For a column of the report, ensure that the column attribute text to display as report is report Standard column rather than the default display text (escape special characters).

  However in the APEX 4.x, using an element in the Image display and support declarative BLOB is preferable to these manual methods. Images can be formatted using the HTML attributes of the element form of property, or via CSS element.

• How to write the trigger for update of 2 tables

  Hi all
  I have 2 tables,
  
  1.lv_data,
  It contains the following fields,

  emp_name        tot_days
   guru                    18
              

  2.leave_data
  It contains the following fields,

   emp_name          From_date              to_date            no_of_days       remaining_days
   guru                    02/05/2012          03/05/2012           2                         

  In the second table, if the data is inserted.
  the no_of_days will be calculated automatically (from to_date - From_date) + 1,
  
  Here, I need to write the trigger to update the remaining_days column,
  
  First table for all tot_days emp_name is 18 days,
  Thus, in the second table every time that the record is inserted.
  the remaining_days must be calculated as follows,
  
  remaining_days: = tot_days - no_of_days and this (calculated) value should be updated in the tot_days column in the first table (lv_data).
  
  Example:

  emp_name        tot_days
  guru                    18
              

  2.leave_data
  

   emp_name          From_date              to_date            no_of_days        remaining_days
   guru                    02/05/2012          03/05/2012         2                          16
  [/code  
  
  Now the first table should be updated like,

  emp_name tot_days
  Guru 16
  
  
  So I need to update to 2 tables,
  can someone help me to update these 2 tables through TRIGGER?
  
  Thank you
  Kind regards

  Edited by: Gurujothi may 1, 2012 19:54

  It is generally considered bad practice to store the value even in 2 places. You are having the kind of problems that you are experiencing now. It is much easier to store in the main table and get the value from there where you need to show in your forms.
