Reading BLOB fields

• Download the image blob field

  Hello experts,

  I am trying to download an image via the input file to convert it to a blob field and then save it in the database.

  So I linked the value of the input file to create the blob through bean, I found on the internet.

  My Page binding components:

  < af:inputFile id = value = "#{UploadBean.file}" / 'inputImage' >

  < af:button text = 'Upload' id = 'btnUpload' action = "#{UploadBean.uploadImage}" / >

  
  

  My Bean:

  
  

  private BlobDomain img;

  private UploadedFile inasmuch;

  public UploadBean() {}

  Super();

  }

  public UploadedFile getFile() {}

  return inasmuch;

  }

  {} public void next (file UploadedFile)

  Inasmuch = file;

  }

  public void uploadImage() {}

  UploadedFile myfile = (UploadedFile) this.getFile ();

  IMG = createBlobDomain (myfile);

  System.out.println (IMG);

  }

  Private BlobDomain createBlobDomain (file UploadedFile) {}

  InputStream in = null;

  BlobDomain blobDomain = null;

  OutputStream out = null;

  try {}

  in = file.getInputStream ();

  blobDomain = new BlobDomain();

  out = blobDomain.getBinaryOutputStream ();

  ubyte [] buffer = new byte [8192];

  int bytesRead = 0;

  While ((bytesRead = in.read (buffer, 0, 8192))! = - 1) {}

  out. Write (buffer, 0, bytesRead);

  }

  in. Close();

  } catch (IOException e) {}

  e.printStackTrace ();

  } catch (SQLException e) {}

  e.fillInStackTrace ();

  }

  Return blobDomain;

  }

  But it seems to me that the file is still set to null after choosing an image, because it throws the following error message:

  <oracle.adf.common> <AdfDiagnosticsJarsVersionDumpImpl> <executeDump> <Pfad für den Dump der JAR-Version :C:\Users\user\AppData\Roaming\JDeveloper\system12.1.3.0.41.140521.1008\DefaultDomain\servers\DefaultServer\adr\diag\ofm\defaultdomain\defaultserver\incident\incdir_45/adf_DiagnosticsJarsVersionDump42_i45.txt>

• Advanced table read only fields

  Hello

  I have a table advanced based on VO.

  I want to do some column read-only fields.

  I did like that.

  OAApplicationModule am = oapagecontext.getRootApplicationModule ();

  OAViewObject vo = (OAViewObject) am.findViewObject ("SearchHeaderVO1");

  Line SearchHeaderVORowImpl = null;

  int fetchedRowCount = vo.getFetchedRowCount ();

  Rank [] rows = vo.getAllRowsInRange ();

  for (int i = 0; i < fetchedRowCount; i ++) {}

  If (rows [i]! = null) {}

  System.out.println ("In makeReadOnly");

  Rows [i] .setAttribute ("EntityCode", Boolean.true);

  }

  }

  What is the right way to go?
  Thanks again
  Varun

  Varun,

  1. create an additional attribute in your VO of Boolean type. ex:-name: customReadOnlyAttr

  2. set this attribute value as the property readonly for each field in the page. as a ${oa. SearchHeaderVO1.customReadOnlyAttr}

  Now in your code, set the value of this attribute programmatically, based on any desired conditions.

  What is the State you want to make these fields readonly?

  See you soon

• API import block and read only fields

  I want to create a custom field for a Contact that will be read only in the interface user of E10, but for that I can import values via import bulk API.  I created my domain via the REST API as a text type and marked read-only; It appears as such in the user interface.  I then create an import via the API definition in bulk and run an import.  The status of the synchronization ends as "warning", and my read only field is not filled.

  I tried the same import API code block using custom fields not unalterable and he succeeds, then I'm sure it has to do with the read-only field.  Is there a way to accomplish what I'm trying to do?

  UPDATE: I received confirmation from someone of Eloqua fields read-only cannot be set via the import bulk API.

• Registration number read only fields of alignment

  APEX 4.0.2 / RDBMS 11G R2

  I would like, in a form of the APEX, aligned to the right a read only numeric value which is calculated by my application.  According to the doc of the APEX, this feature is not available under number of alignment "does not apply to read only fields and the fields where the element HTML Form attributes are specified.

  Does anyone know of a workaround for this problem?  Ideas, suggestions and/or recommendations are welcomed and appreciated.

  Thanks in advance,

  John S

  Hi John,.

  You can try adding some css yourself:

  Add a class to your form field in the Form Element Classes fields HTML CSS attribute and add a property text - align for this class in your css file, or in the header html region.

  For example, put 'rightAlignField' in the attribute of the form element to HTML CSS Classes and add

  to the header html form regions.

• Reading BLOB to SQL Server 2005 using DB Oracle 10 g Link

  Hi all
  
  I'm reading the data from a table in SQL Server 2005 by using ODBC DB link created in Oracle database 10 g (10.2.0.3/4). I do not use oracle gateway.
  
  I am able to read all the data except data BLOB of SQL server 2005. It gives an below error when I try to run the query SELECT * from T_TRANSACTION_DATA@sdeslink within a stored procedure:
  
  ORA-22992: cannot use LOB Locators selected remote tables
  
  Kindly help how to read BLOB from SQL server 2005 within Oracle 10 g.
  
  Best regards!
  
  Irfan

  Irfan,
  In fact, you hit a restriction of RDBMS and is not a problem HSODBC. You will get the same error if you try to select a BLOB in a remote Oracle database.
  There are workrounds, but you must first verify that you can select the remote blob using SQLPLUS as there are some restrictions on the types of data that can be managed by HSODBC.
  What is the data type of the column in SQL * Server can you select using SQLPLUS?

  The other point is that 10.2 HSODBC was desupported for awhile and you need to install and use the replacement product that is the 11g database for ODBC (DG4ODBC) gateway.

  Kind regards

• Save event - make text read-only field if not empty

  I have a document which must have read only 1 field if it is not empty when the form is saved. I have the Document Actions 'spared' configured to run a script that contains only:

  getField("DepositDue").readonly = true;

  The problem is, if I save the document so that it can be filled and saved by adobe reader, this field is changed to read-only. What I need is an if statement to check if this field is empty first, but do not know how to do in this regard. The extered text is a date in the format of date as well.

  The following works for me in paper will save the event, but not the Document spared:

  var f = getField ("DepositDue");

  f.ReadOnly = f.valueAsString;

• script for reading calculated field changes color according to requirement

  I need help to create a script that would do a single reading calculated field to change color if a condition is met.  If the script placed in the calculated event?

  The fields are:

  CourseNum (automatic sum calculates 11 different numeric fields)

  A1p (digital calculated read only field)

  AP (digital calculated field read-only)

  HIGHA (the sum of the A1P and AP) - this is also a calculated read-only field

  Therefore the condition:

  If CourseNum > 20 and HIGHA > = 50%

  then change the background color of the yellow HIGHA

  otherwise, it should be white

  This is your statement. The "or" is the last used operation. So, you're saying, ' if the year 4 and (B1P + BP) > ".45" OR so (B1P + BP)<".30" and="" coursenum="">= "20", then change the background.»

  Try:

  If (form1. #subform [0]...) YearLevel == 4 & ((B1P+BP) > ".45" or (B1P + BP)<".30") &="" coursenum="">= '20')

• [ORA-22905] How to read a field of an object inside another object?

  Greetings,
  
  I'm a student and in an exercise working with Oracle object-oriented programming features.
  
  In the database, we have defined an object type, which is then considered as within another type of object. The thing is, that I can not read an attribute of the internal object. I've read dozens of Web sites, but none of them helped until now. I also read the PL/SQL user's Guide and the reference document.
  
  The internal object is defined as follows:
  

  create type address_t as object (
          street varchar(50),
          city varchar(50),
          pcode number(5,0)
          );

  The external object has an object of type address_t inside:
  

  CREATE TYPE professor_t as OBJECT(
            code number(2),
            p_name varchar(50),
            address address_t,
            );

  There is also a table named PROFESSORS that stores objects of type professor_t
  
  First of all, with a simple SQL test I can see the data inside the Professor of the object, even the address_t of the object:
  

  SELECT * FROM PROFESSORS WHERE CODE = 13;

  Returns the following:
  

  CODE    |         NAME      |       ADDRESS
  ---------------------------------------------------------------------------------
  13      |         JOHN     |       MYSCHEMA.ADDRESS_T('FIFTH AVENUE','NEW YORK',12345)

  The thing is, I want to read the field Street of the object address (of type address_t) inside Professor (of type professor_t).
  
  I saw everywhere where the way forward is to use dot notation, and I've seen examples of the VALUE control, but none of the following SQL statements work:
  
  

  SELECT VALUE(ADDRESS.STREET) FROM(
    SELECT CODE,P_NAME,ADDRESS FROM PROFESSORS WHERE CODE = 13);
    
  SELECT ADDRESS.STREET FROM PROFESSORS WHERE CODE = 13;
  
  SELECT PROFESSOR.ADDRESS.STREET FROM PROFESSORS WHERE CODE = 13;

  I would appreciate if someone could show me how to access the values of the field of the object inside an object.
  
  Thanks in advance,
  -David

• Read only fields become unlocked when PDF is open again

  I created a quote that is has several buttons on it.  The buttons perform many actions such as the Add/Remove lines, add or remove columns, etc.  There is a "Finalize" button at the bottom of the form that locks all the text fields and hides all buttons so that they cannot be changed by the customer when the quote is sent to them.

  The problem occurs when the form is completed, saved, and then reopened.  All the buttons become visible again and the text field becomes editable when the PDF file is reopened.  Is there a way to keep the hidden buttons and text read-only fields?

  Thank you.

  The "State" of the form is not saved automatically. Under the form of file/properties/Defaults make the checkbox 'Keep changes to the scripts to form when registering' is set on automatically.

  How do you define PHOTO_DIR (which was the CREATE DIRECTORY statement)?
  Is the path to PHOTO_DIR a directory that exists on the server (and not on your client machine)?
  The user of the operating system that is running the database on the server Oracle has access to this directory on the server? Can you connect to the server as the operating system user that runs the Oracle database and open the file on the server?

• Image file of reading BLOB and the opening on the side customer

  Dear all,
  I have a table of database with a BLOB data type field and there are files TIFF stored in this column.
  
  I want to open this file on desktop of the client as Tiff soon he call a PL/SQL procedure?
  
  How built-ins or methods, I can use?
  
  Thanks in advance!
  
  Kind regards
  Ali

  As an example of a PL/SQL procedure image file, the following procedure for web enabled (called via Apache and using the module of Apache Oracle mod_plsql ) returns an image.

  create or replace procedure TIFFimage( fileName varchar2 ) is
    b blob;
  begin
    -- read the TIFF blob from image table
    select p.file into b from my_tiff_files p where p.file_name = fileName;
  
    -- create the HTTP response header for the browser
    OWA_UTIL.mime_header( 'image/tiff', FALSE );
    HTP.p( 'Content-Disposition: attachment; filename='||fileName );
    HTP.p( 'Content-Length: ' || DBMS_LOB.getlength(b) );
    OWA_UTIL.http_header_close;
  
    -- stream the content using Oracle's Web Procedural Gateway interface
    WPG_DOCLOAD.download_file( b );
  end;
  

  In this case, the customer will be a web browser. It will use the URL will look something like this:

  http://my-web-server.my-domain.com/pls/TIFFimage?fileName=PrettyPicture.tiff
  

  No need for intermediate files. PL/SQL procedure creates a HTTP from MIME response that contains the image - something that the client (web browser in this case) understand and fully support.

  The same principle applies to any other type of client - he called SQL or PL/SQL - it gets a response - this process / makes this answer.
