  I'm fighting for a long time...
  the question is... the code is below... is that ok or any changes I have to do

  That is really good!

  I have two very minor ideas:

  (1) you have probably issued a command like

  SET  SERVEROUTPUT  ON  SIZE 50000
  

  otherwise, you don't see any output of dbms_output.

  You must include this command in the same script. It makes no sense to run the DECLARE block without it, and it when it is not strictly necessary does not take much time. (This is not a case where the effectiveness is a high priority.)

  (2)

  Define a PL/SQL table that has only a single column that stores the number with the index as type varchar2.
  Store the emp.sal in the PL/SQL table with ename like index.
  Define a cursor of emp table.
  To loop through the cursor and display the name of the cursor variable and the salary of the collection for each employee.

  This looks like a duty. As I read, a LOOP (the cursor loop FOR) was all that was required. You were in the class, I was not: so I could be wrong. In any case, it doesn't hurt to show that you know how to loop through the collection, but also how to loop through the cursor, but you should know that it is possible to read and write in the same loop:

  DECLARE
      TYPE emp_typ IS TABLE OF emp.sal%Type INDEX BY emp.ename%TYPE;
      emp_arr         emp_typ;
  
      CURSOR c_emp IS SELECT ename,sal FROM emp;
      r_emp  c_emp%ROWTYPE;
      v_idx VARCHAR2(20);
      num_total_rows NUMBER;
  BEGIN
      FOR r_emp IN c_emp
      LOOP
          emp_arr(r_emp.ename) := r_emp.sal;
          num_total_rows := c_emp%ROWCOUNT ;
  --      DBMS_OUTPUT.PUT_LINE( r_emp.ename || ',' || TO_CHAR (emp_arr(r_emp.ename)) );  -- Could display here, and skip the other loop
      END LOOP;
  
      DBMS_OUTPUT.PUT_LINE(  num_total_rows );
  
       v_idx := emp_arr.FIRST;
  
      WHILE v_idx IS NOT NULL
      LOOP
          DBMS_OUTPUT.PUT_LINE( v_idx || ',' || TO_CHAR(emp_arr(v_idx)) );
          v_idx := emp_arr.NEXT( v_idx );
  
      END LOOP;
  
  END;

• I'm not able to get the value of an element in the region from the table using Java script

  I have a fixation with two columns area, when the user tries to add a new line without having to fill in the line above, then it should throw an exception. It is the custom page and the home region is located at the end of my page so normal exception raises at the top of the page where the end user referred to in the current. I need to go with popup warning. I built a java script in PR

  code:

  OkButton OASubmitButtonBean = (OASubmitButtonBean) webBean.findChildRecursive ("addrow");

  "if ((a.value)! = ") {input = alert ('check' + (a.value)) ;}} else {alert (' inside the else'+ (a.value));} ");"

  The code above works for entering the message text in the header area, but it is does not make any value if the sub-region of table in advance. Kindly share your point of view on this issue.

• How to get the value of a * Global * Application point of JS

  If we declare an element of the request, which is NOT a level of the page in question, how we get the value of this element in an Action dynamic JavaScript on a page?
  
  For example, we declare a "global" variable as an Application named DEFAULT_AJAX_SEPERATOR and set its value with a calculation of the claim "on the new Instance" a moment later, on a page of the application, we would like to get the value of DEFAULT_AJAX_SEPERATOR via JavaScript.
  
  Page* level syntax element...

  $v( 'DEFAULT_AJAX_SEPERATOR' );

  .. How does not work. I don't understand why it's like $v can only access the elements on the page. However, the APEX is clearly able to get these global values since, for example, they are available in PL/SQL blocks. Also, I know that it is on the session object, because I can see it when viewing the session.
  
  So... What is sauce secret for obtaining this value?
  
  Thank you
  
  -Joe

  Hello
  Use something like this in your javascript code.

  var appItemVal = "& DEFAULT_AJAX_SEPERATOR.";

• How to get the value of the global element using javascript or ajax!

  Hello!
  
  How can I read at global(point application created in the shared components) using ajax or javascript?
  You can imagine that I need to get the value of this element by function as:
  -----
  Function getText() {var itemVal = $x ('MY_GLOBAL_ITEM') .value;}  Return itemVal; }
  -----
  .. .but I can't do it because it is not made to couse of the page it is global element! so, anyone know no work around to do?
  I know that I can make point page and read the value of that, but not what I really need!
  If I have 100 pages and all pages need to use my function, it would take 100 Articles :) - that's why its no good average!
  
  Please, share your ideas!
  
  THX

  Rafix,

  You must use a little AJAX to retrieve a request element value. Three steps in this solution. Implementation of a callable JavaScript function, creating an application process on the request and call the JavaScript function with dynamic action.

  1 set up a JavaScript function that can be called by:

  This function calls the process of application level which has a visibility of the element of your application and then returns the value of points.

  Edit your page and JavaScript code according to the code in the 'function and Variable global statement' of your page. You can also add to the model page, that you use, but you also have to encapsulate this code in the script tags.

  getAppItem = function(pItemName){
      var get = new htmldb_Get(null,$v('pFlowId'),'APPLICATION_PROCESS=GET_APP_ITEM',$v('pStepId'));
      get.addParam('x01',pItemName);
      gReturn = get.get();
      get = null;
      return gReturn;
  }
  

  2. creating an application on request process:

  The application of level process has visibility to your application-level element. It is to retrieve the value of points and it prints the htp buffer. Essentially, this acts as a way to return the values of AJAX calls (the javascript function we set previously);

  go to the shared components > procedures > Create.

  Point process: "We Demand: run this application...". »
  Name: GET_APP_ITEM
  Type: Anonymous PL/SQL block

  declare
     -- get the item name passed into the JavaScript function.
     app_item_name varchar2(30) := apex_application.g_x01;
  begin
      -- print its value to the buffer
      htp.p(v(app_item_name));
  end;
  

  3. call the JavaScript function with dynamic action:

  The function call allows to specify an application-level element name and have its returned value. The trigger event is specific to what you need, but the action must be of type to run JavaScript code. In my case immediately the value of P1_NUMBER to my value of demand points. This code doesn't have to be in a dynamic action, but it helps to stay organized. you could call it from any script tag.

  $s('P1_NUMBER',getAppItem('MY_APP_ITEM'));

• Set and get the value of the item application in Javascript

  Hello guys,.
  Can you tell me an example how to set and get the value of the application element in Javascript, and how do I check if the value of the point of application is null in Javascript, too. I have read a few replies, but nothing worked (e.g. $x (app_item), $v (app_item), $s (app_item) and so on).
  
  Thanks in advance!

  To get the value of an element, use the following syntax:

    alert("The value of MY_TEST_ITEM is " + $x("MY_TEST_ITEM").value);
  

  to set the value that you have just made

    $x("MY_TEST_ITEM").value="Set to this value";
  

  Keep in mind however that you need to send the page in order so that he could be picked up by APEX - javascript is CLIENT SIDE, ONLY! Either that or use AJAX to put on the side server.

• Get the value of the question page before submitting.

  Hello all, I use the Application Express 4.2.5.00.08. I have a question on getting a value for a page element before the page is sent. I have a dynamic action:

  Action: Moving the mouse (on a region/State)

  Real Action: $('a[href*="39"]').each (function (index) {}
  lnk = $(this) .attr ('href');
  $(this) .parent)
  . Parent ('tr')
  .Attr ("href data ', lnk")
  {.mouseover (function ()}
  $(this) .css ("cursor", "pointer");
  Lrowrequired var = $(this) .closest ("tr"),.
  BLOCK = lRow.find("td[headers=BLOCK]").text ();
  $x('P39_BLOCK').value = BLOCK;
  })
  {.mouseleave (function ()}
  $(this) .css ('cursor', 'default');
  })
  });

  I am successfully able to get the value of the line while I'm hovering above the report (and P39_BLOCK is refreshing). But, in this case, the value is not set whenever it changes. My question is, if I need to use this value (say, put an another page element when P39_BLOCK is changed) without submitting the page, how is that possible?

  Kind regards
  MFadel.

  Hi Mohamed,

  That's what bothers! In my first dynamic action, I have real action 'Execute JavaScript Code', which doesn't have a property "Page items to show.". And I need this code to retrieve values from the row of the report.

  On the right, you will have the option 'page elements to present' the dynamic JavaScript actions. Only the PL/SQL. And you do not need to handle things strictly the use of javascript. JavaScript is usually used to manipulate items on the page itself, not the things on the server/session). If you need to present before your PL/SQL block, you can either use AJAX call, or you can create a dynamic action of PL/SQL that runs before your JavaScript. Put this field in the 'submit' page elements and the block of code, just put null;

  Here's a sample in javascript, ajax call. It pushes three elements of the page in the session or in the scope where APEX can access their values. You can return values through AJAX if necessary also:

  $.ajax ({type: 'POST',})

  URL: "wwv_flow.show",

  data: {}

  p_flow_id: $('#pFlowId').val (),.

  p_flow_step_id: page,.

  p_instance: $('#pInstance').val (),.

  "x 01': P39_PAGE_ITEM_1, '.

  "x 02': P39_PAGE_ITEM_2, '.

  "x 03': P39_PAGE_ITEM_3, '.

  p_request: 'APPLICATION_PROCESS = YOUR_PROCESS_NAME'

  },

  success: function (data) {}

  Console.log (Data);

  }

  });

  Then you would have a PL/SQL process called YOUR_PROCESS_NAME that can refer to variables such as

  my_var_1 VARCHAR2 (100 CHAR): = APEX_APPLICATION. G_X01; -Javascript password

  my_var_2 VARCHAR2 (100 CHAR): = APEX_APPLICATION. G_X02; -Javascript password

  my_var_3 VARCHAR2 (4000 TANK): = APEX_APPLICATION. G_X03; -Javascript password

  Can I use in my "PL/SQL procedure? Because in the end, I'm trying to use this value in a PL/SQL procedure:

  To answer your last question, Yes, you can use the P39_BLOCK in your PL/SQL, how you demonstrated above, but you must submit in the 'page' referred to submit box, otherwise it uses the last value that has been submitted.

  What I'm not clear, is do you need really value before executing the PL/SQL or you just want your PL/SQL? If you just try to pass it in PL/SQL and then just use the dynamic action of PL/SQL and pass it by using the "elements of the page to present. '' Remember, if you need a new value to publish on the page, you will need to put these fields in the box "items to display the page.

  If you only need the value of front page because you will use in javascript, somewhere, then reference it with jQuery or js and then use AJAX to continue your treatment.

  A third way, you could do, is to create a dynamic action of PL/SQL that runs before the javascript code that is null; in the body of PL/SQL, but put the P39_BLOCK in the "elements of page to submit" box. Who will just send the page element, and then take action dynamic javascript. But, I don't know why you would do that since you can't have the value submitted for javascript to use.

  Hope that all makes sense.

• ([JDev12c, ADF] 1) how to get the value of a field of the line currently selected in question 2) af:table: flowScope

  Hallo,

  How can I get the value of a field in the row that is currently selected in an af:table?

  I need to pass this value to a setCurrentRowWithKeyValue who took the record to display in another (by a button) called page:

  Limited workflow

  Page1 - goToPage2-> setCurrentRowWithKeyValue-> PAGE2

  I defined a managed bean flowScope for the workflow in which I created the variable 'CodeToSetPage2Row '.

  I will store the value of the field for the selected line in this variable so that I can move on to the setCurrentRowWithKeyValue.

  Could be this method OK? Ore is there any good practice to achieve this goal?

  The managed bean flowScope used to go to the stubborn task may take some values from the outside?

  The workflow defined will be executed in a dynamic region.

  Thank you

  Federico

  Federico, you cannot use a flow variable scope for this page. The region has no access to the bean. You must use a workflow for this parameter.

  To get an attribute of the currently selected line you make slide data vo of control on the page attribute. This will create a link attribute for this attribute. Once this link exists, switch to source mode and remove the component that you do not want.

  The framework passes the value of the current row in this affair of the attribute (table should be in single selection mode).

  Click on the button, you switch the binding of the attribute for the setting of task flow using a setPropertyListener.

  In the workflow, you call the setCurrentRowWithKeyValue with the parameter of workflow as the default activity.

• Get the value of the title field

  My question is simple. Here's my scenario.
  
  I have a check for profile, with an editable title field and a list of options. The user selects a value in the option list and entered a title. When he submits the form, the title of the content check-in must be derived from the value of the option list + the value of the field title. The derivative title must be the concatenation of the value of the option list, and the value of the field title.
  
  My question is how to get the value of the field title using the script of the OIDC? I have a rule with the field of dDocTitle and its derivative field, I have an idoc script that displays the value of the option list in the spin-off title field. I only need to concatenate the value of the editable field title entered by the user.
  
  Thank you. I use UCM 10 g.

  This can be done with rules and profiles of the school boards and derived values.

  If the user enters a title in the field of dDocTitle (this is mandatory) and if you have another field of metadata with a menu drop-down (as conceptual dDocType) you can use the Configuration Manager (rules and profiles) take the value of dDocTitle and dDocType and when checked (it not shown to the user after logging) she'll concatenate.

  in the custom box (you may need to do this because of the wrong inserts quotes with our variables) make sure that it looks like this
  <$dprDerivedValue=dDocTitle &="" ddoctype$="">

  Notes that may be of interest
  How can define you a value derived in a rule using Idoc Script to call a service? (Doc ID 833953.1)

• Get the value of point of contact OFA

  Hi guys,.

  I am new to oaf, so this may seem like a very novice question. I tried several things, but could not solve it.

  There is an advancedtable region in my page. The first column of the advanced table has been put to contain elements of binding while the rest of the columns are messagestyledtext. The advancedtable would be filled with a few details of the item with the first column is the item number. The requirement is to fill in the details of article on click in the item number which essentially appear as hyperlinks.

  I try to get the number of the first column.

  pageContext.getParameter ("itemnumber");    ['itemnumber' is the ID of the binding inside the column inside the advancedtable element]

  This returns null, so I can't get the item number. Can someone please help me solve this?

  Thank you

  Sasmas

  You can see the bottom of thread for "the line being returned as null Reference".

  https://community.Oracle.com/thread/581600

  As an alternative, you can add parameters, p_item_num to the PPR method with value in the form ${oa.current.ItemNumber} (if the number represents the VO attribute name)

  In the processFormRequest, get the value using "pageContext.getParameter ("p_item_num")"

  Therefore, the code will be

   public void processFormRequest(OAPageContext pageContext,
                                     OAWebBean webBean) {
          super.processFormRequest(pageContext, webBean);
          OAApplicationModule am = pageContext.getApplicationModule(webBean);
          String event = pageContext.getParameter("event");
          if ("itemLinkClicked").equals(event)) {
          {
                 String itemNumber = pageContext.getParameter("p_item_num");
  
                  Serializable[] parameters = { itemNumber };
                  am.invokeMethod("fetchItemDetails", parameters);  
  
          }
      }

• Cannot get the value of the session variable (using row wise initialization).

  Hi all

  I have a scenario where I'm trying to get the value of the variable session of two columns.

  Table of database consists of the name of USER, Country_Region, columns Country_SubRegion.

  For example: ChadraKanth, Americas, America West is the data.

  I wrote a Sql query in the block of session initialization:

  Select "CR", Country_Region, Country_SubRegion

  of row_wise_init

  where USERID = ": the USER"

  When I test the RPD code gives the result like this:

  CR WesternAmerica of Americas.

  In my report I have two columns, a region and an another subregion.

  When I try to filter with the session variable "CR" for the column region his error giving: session variable is not initialized with

  This is the default.

  Question:

  1. session variable is contains several values in the column?

  2. how to filter the report on columns of region and sub region?

  Please suggest me.

  Kind regards

  Chandra Khalil.

  Hello

  A session variable cannot store more than one column, 1 variable = 1 value (column 1), horizontal initialization allows to store several lines, multiple values in the same variable.

  If to a user, you have several lines with multiple values, you need horizontal initialization, but it cannot store in the variable the value of the region and subregion.
