• problem with the default value of the parameter in function

  Hi all

  create or replace FUNCTION date_post_message (
  user_lock_in  IN  users.user_lock%TYPE,
  form_type_in  IN users.form_type%TYPE DEFAULT 0 ,
  date_in       IN                       DATE)

    FROM changes
    WHERE date_post_msg <= date_in ;
    RETURN TRUE;
  exception
  WHEN NO_DATA_FOUND THEN
  RETURN FALSE;
  END date_to_post_msg;

  problem: there is null, the function ignore the form_type_in default value 0.
  Why? the default value is valid only in the parameter of the procedure?

  No, can't do this in the signature. You will need to manage this by validating the parameters passed at the beginning of the function.

  It is quite simple. In your case, you might as well test for NULL and fail to function like this:

      FUNCTION date_post_message(
              user_lock_in IN NUMBER,
              form_type_in IN NUMBER DEFAULT 0 ,
              date_in      IN DATE)
          RETURN BOOLEAN
      IS
          v_num NUMBER(1);
      BEGIN
          dbms_output.put_line('Value of parameters : user_lock_in : '||user_lock_in || ' : form_type_in : '||form_type_in||' : date_in : '||date_in );
          IF user_lock_in = 1 THEN
              RETURN FALSE;
          END IF;
          IF form_type_in IS NULL THEN
              RETURN FALSE;
          ELSIF form_type_in NOT IN (1,2) THEN
              RETURN FALSE;
          END IF;
          RETURN TRUE;
      EXCEPTION
      WHEN NO_DATA_FOUND THEN
          RETURN FALSE;
      END;
  

  In other cases of use I would issue a local variable and treat it like this:

          IF form_type_in IS NULL THEN
              l_form_type := 0;
          ELSE
               l_form_type := form_type_in;
          END IF;
  

  Of course, the code should use the local variable rather than the parameter.

  It is a good practice to validate values passed in parameters at the beginning of a function. If you really want to go to the city, discover the Design By Contract.

• Default value for the field date

  Dear all

  How can I do this?

  Sandip,

  In the property Palette, set the initial value property as * $$DATE$ $*. So, it will return the current date.

  Kind regards

• If the default value of the field Date

  I have a DateFiled I need to initialize nuer a date I get a string

  String defaultResponse = "09092009";

  long date = Long.parseLong (defaultResponse);

  inputField = new DateField ("", date, new SimpleDateFormat ("DDMMYYYY"), DateField.DATE | ") DrawStyle.HCENTER);

  but I get '01011970', not the value, I'm putting in... can someone tell me what I'm doing wrong...?

  Kaddy

  You have found '09092009' convert to long, so it does not work as expected. The date is represented as a nuymber of milliseconds since 01/01/1970.

  First proposal, to set the date at this point, you should take System.currentTimeMills)

  To create a Date object, use Date dt = Date (System.currentTimeMills ()) new

  You can also create a calendar from the Date object object, and then manipulate the various components of the date (day, weel, year, etc.).

  Or, you can get a date in a format more known (as on 2009-09-09 12:00) and analyze it using HTTPDateParser.

  Please see the API documentation for details.

• How to change the default value of a parameter and LOV attached to a parameter

  Hi all
  
  I'm new to the discoverer reports and I need the following tasks:
  1. the need to change the SQL of a discoverer report
  2. need to change the default value of the parameter (from constant for the current month). In the discoverer more responsibility when I open the report and go to tools > > setting > > edit
  I can see the value of the default constant is given. On the right side there is a drop down that says "Value". I suppose that if I put a SQL as default, I need to change the drop-down list for sql or something and then put the code SQL. Problem is the menu drop-down is froezen and I can't change it.
  Even if I try to create a new report parameter.
  3 need to change the LOV associated with the element on which is based the setting.
  
  
  I have the discoverer more responsibility to myself and did not have the discoverer administrator (as forms 6i developer desktop tool) tool. My questions are:
  1. can I modify the SQL query using discoverer and responsibility or do I discoverer Administrator tool?
  2. any help on how to get the default value of an SQL query? Currently, it is a constant value.
  3. is there a way to understand is that the LOV is made of the constant values fixed (as a set of values independednt) or they are read in a SQL (value valid table sets)?
  
  Solutions pointers will be greatly appreciated!
  Thanks in advance.
  
  Thank you and best regards,

• Block initialization parameter default value of the session variable used in default prompt as "(toutes les valeurs de colonne)" "

  Hello

  I have a business requirement for a dashboard that we built location to get the users that belong to a certain geographic location to the default view of the dashboard with guests together in their geographic area.  He is just giving them a default view to enhance their experience when they connect each day.   Because of the way that we put the default value for the period of time they watch, with the HELP of SAUVÉ the CUSTOMIZATIONS IS NOT AN OPTION.

  I created the default values for the prompt called "area" in a block of initialization. This variable is called V_USER.

  My problem is that only about 80% of users have a value of 'Area' in the hierarchy of our employees.   I would like to someone else by default "(toutes les valeurs de colonne)". "  I was unable to understand how and where do.

  Some of the things I've tried:

  (1)	Setting the default value in the initialization of an empty space block ("in SQL)
  (2)	Setting the default value in the initialization "(toutes les valeurs de colonne) block '"
  (3)	Setting the default value in the initialization block 'null '.

  None of them have worked and the result is that the user who does not have an area ends with a load of zombie dashboard, and while the guest gave rise to fashion "- select value -", the user must press "Apply" again to get the dashboard to display the data.

  The text which lies behind the encircled area in green below correctly becomes the value of the variable to V_USER (it is empty as default and I don't have a box).

  For @{biServer.variables ['NQ_SESSION.]} {[USERS ']} the default zone must be @{biServer.variables ['NQ_SESSION.]} {[V_USER']} {}

  In the red circles below you can see that the guest actually becomes a value: *) nqgtu(* )

  
  

  The illustration below indicates the default value for a user without a box. the second quick block is not updated until you press on apply again...

  

  Thanks for your comments.  I was not able to make this work for my needs.  I have however to solve the problem by changing using a 'SQL result' for my default selection.  Then I created a query that returns rows NULL unless there is a correct answer:

  SELECT 'Service Delivery MOS '. "' Organizational hierarchy. "" Area ".

  "MOS DELIVERY."

  WHERE ("organisational hierarchy". ("" Area number "> 0) AND ("Service Delivery MOS". "Organizational hierarchy" "." " Zone' = ' @{biServer.variables ['NQ_SESSION.]} {[V_USER']} {} ")"

  The "returns no line' I mentioned above resulted in all values being selected.

  Hello

  I think it's good if it fits your need.

  But why you have these fields in the form?
  created by: APPL_USER
  CREATION_DATE SYSDATE
  last_updated_by: APPL_USER
  last_update_date SYSDATE

  Concerning

  For the date, you can use groovy expression adf.currentDate to set the current date. reference http://adfgouravtkiet.blogspot.in/2012/11/how-to-set-default-values-for-entity.html

  You already have ways to use the sequence.

  How do you add a new value in the form. You're creating a new line of your page (user interface) and by engaging with validation operation? Unless you commit you will not be able to see anything in the table.

• Can set the default value in the field with the rule

  I have a rule to set the xWebStartDate to dateCurrent(), but it does not work. I disabled all other rules, so there is no conflict. This rule is only to try to fix the date of xWebStart, nothing else.
  'Use the activation of rule condition' is checked. I selected 'Action of use' and 'check in Selected. I have added the xWebStartDate field and I have a default custom
  < $dprDefaultValue dateCurrent () = $ >
  Thus, it is for content that already exists and someone is to check in a new revision.
  I know that my rule works, because I added the dDocAuthor field and set it to "infOnly" and that works. This problem occurs if the action is updated also. But for check-ins again, I put the xWebStartDate to dateCurrent successfully.
  
  Update: it's existing content, which already has a xWebStartDate. The rule must replace the existing value.
  
  Edited by: ironarm February 1, 2013 17:58

  In your case, you cannot use default value for the new revisions, because your content is already a value for the metadata field.

  Alternative:
  (1) change your rule
  (2) on the general tab, check "Use activation Condition rule" and click Edit
  (3) in 'Edit Activation Condition' window, click on the tab "side effects".
  (4) add the following...

  <$if isCheckin $> [[%or you can also use (IdcService and IdcService like "CHECKIN_SEL_FORM")%]]
      <$xWebStartDate=dateCurrent()$>
  <$endif$>
