  Dear all,
  
  Please tell me how to compare the new values with the old values in triggers.

  Hi, the employee example is in the document. You'd better read yourself.

• How to display the current value on TOP in a LOV

  Hello
  
  I'll have something to say that p1_type a LOV with the following SQL query-based.
  

  select emp_type d, emp_typ r
  from emp

  default results

  EMP
  VEN
  CON
  GEN

  suggest that the current value of P1_TYPE is CON... is there a way... while displaying on the screen, CON should be the 1st element to display in the LOV.

  CON
  EMP
  VEN
  GEN

  Equally, if the current value is - EMP... display must be

  EMP
  CON
  VEN
  GEN

  Hello

  This can be done without a statement from the UNION. See: [http://apex.oracle.com/pls/otn/f?p=33642:249]

  This example uses:

  SELECT X.ENAME d, X.EMPNO r
  FROM (SELECT CASE WHEN EMPNO = :P249_EMPNO THEN 1 ELSE 2 END SORTORDER, EMPNO, ENAME FROM EMP) X
  ORDER BY X.SORTORDER, X.ENAME
  

  The element that corresponds to the selection gets a SORTORDER 1 value, all others are 2. This value is then the primary sort for the list order

• How to make the current value by default to all controls both

  Choose 'Data Operation'-> 'Do current Default value' to several controls requires a lot of clicking. Is it possible to do so with a single click?

  Yes.  If you select no control, he says 'Do the current default values' and it does all the controls at the same time.  If you have a control is selected, then it does so only the selected controls.

  Reset the current values default works in the same way.  Do not select anything, he does all the controls at the same time.

  Here the ADD_USER procedure will convert the password and stores in the Table app_users in encrypted form.
  
  In my application, users can change their password,
  So I need to compare the password entering the Current_password field with the password encrypted in the app_users table.
  So I used the following code,

  declare
    l_x varchar2(30);
  begin
    select username into l_x
          from app_users
      where upper(username) = upper(:P7_USERNAME)
        and password = :P7_CURRENT_PASSWORD;
    return (true);
  exception
    when no_data_found then
      return (false);
  end;

  This code works fine when the password is stored without encryption, but it displays error, after encryption
  
  because the password entered is simply password and not encrypted if the two are different even if the user enters the correct password.
  
  Please tel me how encrypt the entered password to compare with the encrypted password.
  
  Thank you
  Kind regards
  gurujothi.

  Hi guru,.

  When you say comparing it is obvious that both must be in the same format, so either you have to compare both encrypted or not encrypted.

  Do you have an example on apex.oracle.com?

• How to check the current values of COMMIT_WAIT and COMMMIT_LOGGING

  Is it possible that you can check in a session to determine the current settings for COMMIT_WAIT and COMMMIT_LOGGING? I am not referring to a situation where they are defined via ALTER SYSTEM and changed the world, but changed using ALTER SESSION and locally defined. I'm currently testing a trigger to do it for a very specific batch user and just need to be able to log on and check if the adjustment was established successfully or not.

  >

  >
  Well, since these are the initialization parameters, you can check the PARAMETER V view $

  select name, value from v$parameter
  where name like 'commit%'
  
  NAME,VALUE
  commit_point_strength,1
  commit_write,
  commit_wait,
  commit_logging,
  

  And after changing their

  alter session set commit_logging = 'IMMEDIATE';
  alter session set commit_wait = 'FORCE_WAIT' ;
  
  NAME,VALUE
  commit_point_strength,1
  commit_write,
  commit_wait,FORCE_WAIT

• How to compare the 3 values in table

  Hi all

  This is my first post so be tolerant

  I need to find "bad values" in the table, it will be easier to explain with example:

  I have a table like this: 0 0 0 0 0 0 0 0 5 0 0 0 0<- so="" "5"="" is="" the="" bad="" value,="" my="" method="" is="" to="" check="" two="" of="" nearby="" values="" so="" x(i-1)="0," x(i)="5" x(i+1)="0," and="" if="" checked="" value="" is="" more="" than="" 25%="" bigger="" or="" smaller="" it="" should="" be="" replaced="" by="" average="" of="">

  example: 0 1 2 3 4 9 6 7 8<- bad="" value="" is="" 9,="" and="" result="" of="" my="" filter="" should="" be="" (4+6)/2="">

  I did it using the formula node (not 20% and no way, but the point is the same) and it works but now I want to do without C and I had a lot of problems because of the size of the array memory is 10000.

  I joined thah vi and signal, you can test that it works very well

  Thank you

  ... What is the problem?

  Because the first incorrect value is the point of 2780, because it is also disabled because the average of neighbour is biased by the incorrect value to 2781.

  You could jut blindly replace all values with the value that has the lowest absolute value among the three points that we have. Here's a quick project, seems pretty good, but it really depends what you want.

  No problem. Should be as simple as taking my query and replace 'data' a 'test', but you can change the order of Analytics at snap_id

  I would like to know how I could access the old value of an attribute in backing bean.
  I know I can get it in terms of EntityImpl with the getPostedAttribute function,
  but as I see that I'm not allowed to access this function in the ViewImpl.
  I get this error:

  Thank you very much!

  You can add a transitional attribute to the entity object to hold the old value of the desired attribute, then you can add this attribute to the view object.

• Get the current value of a control of the ring

  

  I have a control of the ring that has the following values. See attacment. I need to get the current value of this one and use it as input for another function, but First I would like to get the current value and save ina text file. I tried this

  if (event == EVENT_LEFT_CLICK_UP) || (event == EVENT_LEFT_CLICK_DOWN)
  {
      int p;
      GetCtrlVal (panelHandle, PANEL_RINGSLIDE_1, &p);
      FILE *OutFile = fopen("C:\\Users\\Student\\Desktop\\ringtest.txt","w");
      fprintf(OutFile,p);
      fclose(OutFile);
  
  }
  

  I need to get the current value of the ring (& p) to write to the file ringtest.txt.

  Also, I need to use this value (& p) as another entry in the same program.

  IE value of & p must be used in

  b = c * 5; where c is the value of the current & p.

  Can any 1 help?

  You're right: EVENT_LEFT_CLICK_DOWN is not a valid event for the CVI. Valid events are listed in the userint.h file, and are the only events that can be caught in the trap in a point of order. On the other hand, you're assuption on EVENT_VAL_CHANGED is correct: you can trap forget the EVENT_CLICK_UP event.

  According to the second question, looking at the definition for fprintf you must pass a string format as the second parameter to the function, then the value to write to the file. In your case, the correct syntax is:

  fprintf (OutFile, "%d", p);

• JUCtrlListBinding - get the current value of the list

  Hello.
  (Win7 Jdev 11,1,2.)
  I saw a personal code in the book 'Oracle Fusion Developer Guide' to get the current value of the listItem as below:
  Import oracle.adf.model.BindingContext;
  Import oracle.binding.BindingContainer;
  Import oracle.jbo.uicli.binding.JUControlBinding;
  Import oracle.jbo.domain.Number;
  Import oracle.jbo.server.ViewRowImpl;
  
  BindingContext bindingCtx = BindingContext.getCurrent ();
  BindingContainer links = bindingCtx.getCurrentBindingsEntry ();
  JUControlBinding listBinding = null;
  listBinding = (JUControlBinding) bindings.get ("JobId");
  ViewRowImpl selectedListRow = null;
  selectedListRow (ViewRowImpl) = * listBinding.getSelectedValue () *; :(
  String jobIdValue = (String) selectedListRow.getAttribute ("JobId");
  Number of maxSalary = (Number) selectedListRow.getAttribute ("MaxSalary");
  
  but Jdeveloper cannot find the method getSelectedValue() to listBinding.
  Help me please to understand the correct method. !
  Thank you

  Declare the type of the variable listBinding as JUCtrlListBinding instead of JUControlBinding. The base class JUControlBinding does not contain a getSelectedValue() method, this method is defined in the subclass JUCtrlListBinding.
