• How to add an imaginary line in the result of the value of a SELECT statement.

  Hello all-
  
  I have requirment to add an imaginary line in the result set of a SELECT statement.
  
  For example lets say it is a pay table having the following columns:
  
  Number of Payment_id
  status varchar2 (10)
  number amount
  date of payment_date
  
  so here's the data: -.
  
  Payment_id status amount payment_date
  applied 1 100 12/07/2008
  2 Reversed 200 01 / 06/2009
  Applied 3 300 01 / 07/2009
  
  
  Here is my SQL
  
  Select * form payment where payment_date > = 01/01/2009
  
  The output will be
  
  2 Reversed 200 01 / 06/2009
  Applied 3 300 01 / 07/2009
  
  My desired output is less than
  
  2 Reversed 200 01 / 06/2009
  Applied 3 300 01 / 07/2009
  reversed-200 2, 01 / 06/2009-(Dummy Row)
  
  Third line here is the imaginary line that I add when the status is "reversed".
  
  I would be very grateful for any help on this...
  
  Thank you

  Cartesion join against a shadow table is a useful method to create a fictitious line:

  with my_tab as (select 1 cust_id, 1 Payment_id, 'Applied' Status, 100 Amount, to_date('12/07/2008', 'mm/dd/yyyy') payment_date from dual union all
                  select 1 cust_id, 2 Payment_id, 'Reversed' Status, 200 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                  select 1 cust_id, 3 Payment_id, 'Applied' Status, 300 Amount, to_date('01/06/2009', 'mm/dd/yyyy') payment_date from dual union all
                  select 2 cust_id, 1 Payment_id, 'Applied' Status, 100 Amount, to_date('12/07/2008', 'mm/dd/yyyy') payment_date from dual union all

  NB. You may need to mess around with the order if that is not in the order you want. You did not mention what the rules were for all orders expected, so I composed my own * {;-)

  Also, I added a (cust_id) identifier to differentiate different types of payments, as is usually the case. Remove unless it is not applicable to your case.

• [ADF, JDev 12.1.3] How to hide menu items based on the logged in user

  Hallo,

  When the user logs on successfully, the applitacions led him to the main.jspx page.

  The main.jspx page has a menu bar that contains all of the available menus, submenus and menu items.

  After the connection, when the main.jspx page loads I would hide all the menus, submenus and menu items that the user is not qualified to see/use (I read the database).

  You kindly tell me which is the way the cleaner to achieve?

  Thank you

  Hello rohanwalia,

  Sorry, but I need more help

  I guess that the solution is to create a method in the AM who - reading form the database - returns a structure that indicates for each menu item should be visible or hidden.

  • How can I use the data returned by this method?
  • I call in a managed bean specifically dedicated to the management of the menu? Can I also use the already existing media bean, I created for the page?
  • What scope should have the bean?
  • Don't you think that it is better to define a 'visible' variable Boolean (initilized depending on the result of the AM method) for each menu item and how to bind the Visible property of each menu item to the variable respective in the bean in the bean?
  • Or I can loop the result of the method AM setting the Visible property of the menu items? In this case, I guess that all the menu items must be mapped into the bean by user interface variable. Am I wrong?
  • Is it not possible to write a method which, of the AM directly, hide the menus not necessary on the page (so without using a bean)?
  • In general, which are the correct always to hide menu items:
    • (1) before the page is sent to the browser (as "I can do it with PHP);
    • (2) once the page is loaded in the browser (as I can do it with JavaScript)?

  If you could give me some more detailed advice... I would be very happy.

  Thank you

  Federico

  (1) its best to make the treatment inside the method. You can return the parameters as normal java method.

  (2) Yes, you can use bean already exists in the project. But better to create a separate bean for this task of menu.

  (3) scope should be request unless you need to persist the attributes between requests.

  (4) Yes it is possible. You can define and initialize a Boolean variable with the results you get from the table based on the menu items should be made visible.

  (5) If you use the approach to point 4, then also you have to loop through the table menu items and set Boolean variables of bean. Yes you are right for the second part.

  (6) I'm not sure about this approach. How will you map it to your menu mode. It takes research.

  (7) before the page is loaded. I share with you links in above post with which you can do this.

  I hope this helps.

• How to prevent navigation (action) based on the result of actionListener

  Hello

  JDev 11.1.2.4

  I have a command with an actionListener and an action button. In my actionListener I check certain conditions and if they are met, I want to access. If this isn't the case, I don't want to come back (the property of the action).

  Is there a way to stop the cycle of life after the actionListener under certain conditions?

  Thank you

  You can set a property in the earpiece of the action that you want to navigate or not. Based on this property, you can define action programmatically.

• How to create a report based on the item selected from the list of selection?

  Hello

  I created a tables_LOV based on:

  Select table_name table_name user_tab_cols r, d

  where column_name like '% _type % '.

  Then I created a ListOfTables page element, display in a selection list and pointing to tables_LOV.

  I run the page, and I can choose the table I want in the drop-down list.

  How to create a report based on the selected element? (ex: select * from selected_table)

  Thanks in advance

  Salah

  Hi Salah,

  Allright, take a look at this page: http://apex.oracle.com/pls/apex/f?p=vincentdeelen:collection_report

  I think that simulates what you are trying to accomplish. I've implemented the simplest method I could think of.

  The report is based on a collection of apex. If you are not familiar with this, you should study the documentation: APEX_COLLECTION

  To recreate my example, you should:

  (1) create a report (interactive) on your collection

  SELECT *
     FROM APEX_collections
   WHERE collection_name = 'MY_COLLECTION'
  

  (2) create a selection list page_item for the tables that you want to display (in my case, this is called "P38_TABLES")

  (3) create a dynamic action that triggers on the evolution of your selection list page_item. Dynamic action must be a parade of PL/SQL procedure the following code:

  declare
    l_query varchar2(4000);
  begin
    l_query := 'select * from '||:P38_TABLES;
    if apex_collection.collection_exists
          ( p_collection_name => 'MY_COLLECTION' )
    then
      apex_collection.delete_collection
        ( p_collection_name => 'MY_COLLECTION' );
    end if;
  
    apex_collection.create_collection_from_query
      ( p_collection_name => 'MY_COLLECTION'
      , p_query           => l_query
      );
  end;
  

  Make sure that you add your page_item 'Page to send items' section.

  (4) add a real extra action that makes an update of the report area.

  Here are two photos describing the da:

• dynamic action turns an article based on the result, and checks the database!

  I use Apex 4.1
  
  I do not know how to accomplish the following:
  If a pick list is changed, a function is checked and based on the results of a another field is disabled or enabled.
  
  I created a dynamic action (change) that executes a PL/SQL code, now I need to disable the other element.
  
  the problem is that I can't save the dynamic action because of the sign #.
  
  example:
  Start
  HTP.p ("< script type =" text/javascript"> '");
  HTP.p ('$('#P35_FT_00010_DOC_NO').attr ("readonly", "true")');
  HTP.p ("< /script >");
  end;
  
  I tried document.getElementById, but an error occurs also when I try to save.
  
  I think the wrong way?... Help, please

  1. create a step forward (not the simple/standard one) dynamic action.
  2. create initially unconditionally (the wizard will not let you take the PL/SQL expression as a condition but we will go back and change it later)
  3 assume that TRUE from your PL/SQL will lead to disable the item, then choose 'Disable' and the item you want to disable.
  4. Once created, go back in the DA and change the status of PL/SQL expression and put your PL/SQL in there (suppose you have a function returns boolean called MY_FUNC and TRUE to him means disable).
  5 copy the DA in its entirety to a new DA will be FALSE to activate the element.
  6. Once copied, go into the new DA and change the status of PL/SQL to NOT (my_func).
  7 change the REAL action of the DA to activate the element.

  So now you should have two similar DAs... one for when MY_FUNC is true and disables the element, a when "NOT (my_func)" is true and allows the element.

  If you do not disable, you can run javascript instead to set readonly. It seems that this is kind of what you tried to do, but you seem to use a jQuery selector, I suppose that (I did not recognize your syntax to off the bat)?

  Try to use the javascript API instead Apex:

  if ($v('P35_EN_DIS_DOC') == 1 )
    $x('P35_FT_00010_DOC_NO').readOnly='true';
  else
    $x('P35_FT_00010_DOC_NO').readOnly='';
  

• How to add a new language to the language and region of the Panel

  Hello
  Setting preferences in Mac OS X, I could ' t help noticing the huge amount of languages available in the Mac OS X El Capitan. Located in same languages like Klingon, Navajo and Latin - and of course, this looks like a great tribute to the rich diversity of languages in humanity. However, Mac OS X El Capitan still missing a language - my own. How can I add another language to the language and region of the Panel? How Klingon and Latin is?
  Of course, I have this Internet search, but nine out of ten results were some tutorials explaining how to add an EXISTING language to the ones I already have.

  Thank you.

  Rui Valente

  You just 'Add' a language. You would have to edit all applications to create strings of replacement for all menus, dialog messages, buttons, etc., that it doesn't translate from one language to the other. Each application has a list of strings mapped to the display string for each supported language. The localized string replaces the generic string in the user interface element.

  You can try to contact Apple and volunteer to locate the operating system, they would have confidence in you (unlikely) or hire a person to validate your work.
