• Help with downloading blob data type

  Can Hi all, someone please help me with the download of blob data types. I created the following table, as well as triggers and seq. However, when I try to run the program I get the following error.

  Images will usually be on the client. If the customer needs to read binary image data and argue that the database for storage.

  Like Mike suggested, the customer can be a web browser, do a upload of file from the database. This example uses Apache and MOD_PLSQL in the web layer. See understanding mod_plsql for more information on creating a loading table in the database, and how the HTML form should look similar to the web client to submit a file upload.

  Oracle Apex simplifies it for you.

  Another method is to use DBMS_LOB - client creates a BLOB in the database, bed a piece of the image file, and then write add this piece to the BLOB.

  The customer can also support LOBs via a local client interface or o - o class. This generally allows to create a bind variable LOB and argue that the database.

  And no, you cannot use SQL * more as a client to download files. If the command line is preference, use SQL * Loader to load and submit the files of the database.

• The length of the BLOB data type.

  Hello world. I have a question about the Oracle Blob data type.

  I need to store Image data in my table, there are 4 fields that store 4 different images for a record in a table.

  The size of the image would be no more max 500Ko,

  It is advisable to specify the data type of column as just the BLOB (which is default to 2 GB size)

  Or specify the datalength?

  Length is specified in number of bytes, it is the same as a byte? so I go for BLOB(500K)?

  Kind regards

  Glen.

  You cannot specify a maximum size on a column of type BLOB.  There is no such thing as a BLOB (500000).  It's just a BLOB.

  Unless you are on a rather old version of Oracle, the maximum size of a BLOB is much more than 2 GB - depending on the size of block in a recent version of Oracle, the maximum size is in the range of TB.  Oracle, of course, will not affect TB of disk (or same GB drive) to a value which is only 500 KB.  It will affect only what suits him (according to the size of the segment specified in the definition of the BLOB, and other settings of BLOB storage).

• Best approach for the transmission of data and images

  We you write an app that will allow the user to take a picture of a document and enter a few bits of information about the document and then send it to our server. It is a mobile extension to a larger system of document management to back office we develop in-house so the intention of this BB app is not not to distribute to the masses.

  What is the most practical approach to transmit data and images captured on our server?

  -FTP - fooled with it some and a pain

  -WebService - did not attempt

  -Send an email with the picture attached - seems to work very well

  Is there another approach, should I consider?

  If you do not already things that communicates to the Server backend, e-mail is probably the easiest way.  Crosses all the issues of the segmentation of the image that you would have to do with the Web Service or FTP.

• 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!

• Dynamic PDF up to 200 images, the size of the pdf is greater, cannot save the data and images to the form

  Hi all

  My client would like to dynamic images up to 200 photos to my forms. It works very well. However, when I add images up to 35 images. I could not add images to shape more. Then I save data on the form. All the images and the data entered on the form are missing. I don't know why.

  If I add only 10 images - I can record data and images on the form. 15456 KB is the size of the pdf.  I was unable to add more photos or data on the form.

  There may be a problem the size of the pdf? How big can make a limited dynamic pdf?

  Can save us the information and images as much as we want?

  I spent two weeks to work and trying to figure out this problem. However, it is not successful.

  Help, please

  Cindy

  You must ensure that your users do not import large images.

  Therefore, you can use a script on the change event of an image field that checks the size of the data and warns the user if the file is too large.

  function formatNumber(number) {
      var num = number + '',
      x = num.split('.'),
      x1 = x[0],
      x2 = x.length > 1 ? '.' + x[1] : '',
      rgx = /(\d+)(\d{3})/;
      while (rgx.test(x1)) {
          x1 = x1.replace(rgx, '$1' + ',' + '$2');
      }
      return x1 + x2 + "KB";
  }
  
  var sizeLimit = 200, //allow upto 200KB images
    thisSize = Math.round((this.value.oneOfChild.value.length * 3 / 4) / 1024);
  
  if (sizeLimit > 0) {
    if (thisSize > sizeLimit) {
    xfa.host.messageBox("Note: With " + formatNumber(thisSize) + " the size of the imported image is greater that the recommended maximum of " + formatNumber(sizeLimit) + ".\nLarge images can cause a insufficent performance.\n\nIf possible, use images with the following recommended specs:\nFormat:\t\tPNG or JPG\nColor depth:\t8 Bit (higher is not supported)\nColor space:\tRGB (CMYK is not supported)\nFile Size:\t\t" + formatNumber(sizeLimit), "Recommended image size exceeded", 3, 0);

• Copy the table data (including images) of InDesign to Excel (or other formats such as RTF)

  Hello

  We have a problem trying to get data to InDesign to Excel.

  He has this price list in InDesign, with images and small "icons" (also images) that indicate which element appears under the main image for each row in the table. Each line of 'table' can contain a number of elements, separated by return cart + line break or a similar combination.

  The problem is that we can't get good data and images appear in any other editable format. Copy and paste directly into Excel was still the most successful, but here the images are lost. Export to PDF and Acrobat Pro, exporting to other formats always seem to fail in a way or another (paintings take place on top of the other, images and so on, has lost different for the different export formats).

  

  Data copied to OpenOffice Calc (and then saved as a file in excel format). Yellow areas added to show where the images were in InDesign.

  Price a bit blurred in the picture showing above.

  Are there good ideas how to copy the InDesign table to another editable format (which requires no licenses Adobe...)?

  Thank you

  Andreas

  I didn't notice the direct export from InDesign to RTF. You had to put the cursor within the story make this option appear!

  It is really good, and I sent the result to those who will use it, for them to check if she's good enough and if they can take for excel or work with him in the RTF format as is.

  Thanks a lot for pointing out this option!

  It does not make sense to try to build a literal string that represents the binary data in a GIF file and that insert a BLOB using an INSERT... Statement of VALUES.

  You can use the first approach (dbms_lob.loadfromfile) to load a GIF file (or any file) into a BLOB.
  If the image you are trying to load is not a file on the filesystem of database, you can use SQL * Loader on the client machine to load the data, or you can write an application in any language you want that reads the data from the file and inserts it into the BLOB by using the API in your language / framework. You have not told us what language and framework you use, but it shouldn't be too hard to find a suitable example. For example, if you use Java and JDBC, here is an example of loading a GIF in a table.

• How to find the broken blob data

  I wrote a program sqlloader to load all the images in the table above, there are a few rows of data where the photos have not get uploaded, which shows the user but photo id is empty, how to identify such lines. Please suggest me
  
  Thank you
  Sudhir

  Your photo_blob column can have NULL values, in this case you can find them with something like:

  select id
    from hr_employee_details
   where photo_blob is null
  

  Or the photo_blob was filled with a LOB Locator is valid but contains no data. These cases can be found with something like:

  select id
    from hr_employee_details
   where dbms_lob.getlength(photo_blob) = 0
  

  Or you could have a case where some of the bytes actually enter the blob, but not all resulting in an invalid image. Who is going to be more difficult, try so the other two cases first ;-)

  I try inserting the hexadecimal string long in the blob column. As it allows for no make using ordinary SQL statement due to the limit of 4000 characters.

  Variable string ( varchar data types) into the engine SQL is limited to 4000 bytes.

  So don't use a literal to bind. DBMS_SQL has several Bind() calls that support different types of data: according to the data type of the value of binding that you specify. So when you call Bind() with a string literal, that unite us will be like an affair of varchar2 . Not a LOB. And a link of chain cannot accept that max 4000 bytes.

  As the column being the insertion is a CLOB/BLOB, you must use a LOB Locator instead.

  A better approach would be to create a LOB Locator variable in your PL/SQL code. Commissioning using DBMS_LOB. CreateTemporary(). Use DBMS_LOb.Write () to create the content.

  Then bind this variable of reference using the DBMS_SQL. Bind() call.

  The fundamental question is to use the correct data type in the call to bind() - and is not implicit data type conversions. As Binder a string and then force the SQL engine that convert implicitly to type of LOB data to copy this value into the relevant column of SQL.
