• Execution plan will change if I use the variable binding instead of the literal value?

  Hi guys,.
  
  Suppose I have a select "... Of... WHERE ID = 2 and... "if I go to use the variable binding instead of the literal value 2," SELECT... " Of... WHERE ID =: p_id and... ", the execution plan change?
  I test multiple statements, the plan does not change, but I don't know if it would even as well as in some other cases.

  Hi, sorry for the unclear post, it's 11 GR 2.

  As Sybrand already mentioned, there are a lot of change that came in the implementation of the bind variable in some versions of Oracle db. Since you're on 112, it is still true with the introduction of Adaptive Cursor Sharing . Please have a read on it since the post below written by the development of Oracle optimizer group.

• Use sessionScope as the value of the Variable binding

  Dear all,
  
  I have a variable in sessionScope, and I want to use it as a condition of application of a ViewObject.
  
  I found a thread talking about, there's only one: (Re: set the value in the global variable. )
  How to use the value in the scope of session groovy script?
  
  Model project:
  Set variable in the scope of the session:
  ADFContext.getCurrent () .getSessionScope () .put ("Empno", empno);
  
  Getting value of session scope:
  Object empno is ADFContext.getCurrent () .getSessionScope () .get ("Empno");.
  
  ViewProject:
  Set variable in the scope of the session:
  FacesContext.getCurrentInstance () .getExternalContext () .getSessionMap () .put ("Empno", empno);
  
  Getting value of session scope:
  Object empno is FacesContext.getCurrentInstance () .getExternalContext () .getSessionMap () .get ("Empno");.
  
  Getting value of scope jspx page session
  #{sessionScope.Empno}

  Hi Samson,.

  Here are the groovy expression to access the value of the sessionscope:

  adf.context.sessionScope.role
  

  But, as the said John instead to access the session of the model can be a method of model (whether in AMImpl or voImpl) who takes the role as a parameter value and sets the value of the variable binding of the vo, then call this AM from the bean method passing the role value by getting the scope of the session.

• How can I pass a value to a variable binding in a report query?

  I did a query of report to print a PDF report, with a dinamyc source query that has a connection variable, like this:

  SELECT EMPNO, EMPNAME, EMPDEPT

  FROM EMP

  WHERE EMPNO =: PARAMETER;

  I want to call the report print directly from a page, by using the url print showed by apex:

  f? p = & APP_ID.:0 : & SESSION. : PRINT_REPORT = MYREPORT

  How can I pass the value of the variable binding: PARAMETER using this URL?

  I don't think you can use the url parameter passes in a report query.

  the binding variable: PARAMETER must be a page element or an element of the application.

  use the "include session information and application" in the defination of report query to bind the value when the report is run

• Setting value to a variable binding

  Binds the values of variables can be access with this:
  
  AttributeBinding deptBinding =

  Can I set the value of a variable binding in the same way?
  
  To define a value of binding, I currently have access to the ViewObjectRowImpl and make a setVar (x) in order to get, but it's very hard. I would like a more direct via liaison system if possible.

  Yes you can set it as

  AttributeBinding attr = (AttributeBinding) bindings.getControlBinding ("test");

  This is the way of declaring bind variables in SQL * more.

  In a PL/SQL block, you do not use bind variables like SQL * more. You just use normal variables. The PL/SQL engine is smart and sends SQL statements to the SQL engine containing all PL/SQL variables converted to bind variables. If it works transparent in PL/SQL and you don't have to do something more.

• ADF where can I set the variable binding VO?

  I created VO with bind variable 'BPM_USER_NAME '.

  In VOImpl.java I have getter and setter:

  public void setBPM_USER_NAME (String value) {}

  ensureVariableManager () .setVariableValue ("BPM_USER_NAME", value);

  }

  I plugged my .jspx to BephorePhase - #{pageFlowScope.SimpleBean.beforePhase}

  My SimpleBean.java beforePhaseof the method:

  Public Sub beforePhase (PhaseEvent phaseEvent) throws SQLException {}

  If (phaseEvent.getPhaseId () == PhaseId.RENDER_RESPONSE) {}

  Logger.Warning ("InventoryIlliquid - BeforePhase");

  FacesContext fctx = FacesContext.getCurrentInstance ();

  You cannot use list as a bind variable. Use:

  SQL> create or replace PROCEDURE get_data (p_data IN OUT SYS_REFCURSOR,
    2  p_id IN varchar2)
    3  is
    4  sql_str varchar2(100) := 'SELECT * FROM tab WHERE tab.X IN (' || p_id || ')';
    5  begin
    6  open p_data

  ---------- -----
           3 rr
           4 rr
  
  SQL> 
  

  Or, if you want to use bind variable, use the composite type. Something like:

  SQL> create or replace
    2    type NumberList
    3      as table of number
    4  /
  
  Type created.
  
  SQL> create or replace PROCEDURE get_data (p_data IN OUT SYS_REFCURSOR,
    2  p_id IN NumberList)

• $a_report to refresh a report, but it is not picking up the variable binding

  Hello
  
  APEX - Express 4.1.0 Application
  Browsers - all
  Database - 11g 2
  
  I have a tree on a page region. When a user clicks on a leaf of the tree, I want to be able to use the ID to refresh a report in a different region on the same page
  
  Code for when the user clicks on the map
  
  $('div.tree_li_a').click (function() {}
  
  node_id = $(this).parents('li:first').attr ('id');
  
  If (node_id.substr (0, node_id.indexOf('|')) == 'Y')
  {
  $s ('P4_SELECTED_VALUE', node_id.substr (node_id.indexOf('|') + 1));
  Alert ("value: ' + $v ('P4_SELECTED_VALUE')");
  $a_report ('28576803999973770 ',' 1','20 ', ' 20');
  $a_report ($v ('P4_REPORT_ID'), '1','20 ', ' 20');
  };
  });
  
  SQL statement
  
  SELECT *.
  PRODS p WHERE PROD_CODE =: P4_SELECTED_VALUE
  
  The problem I have is that when the report is run (I know it's refreshing) the P4_SELECTED_VALUE of the link variable is null.
  
  Pop alert contains the correct value, and when I do the visible P4_SELECTED_VALUE it also contains the value?
  
  Any help is very appreciated
  
  Rob

  Rob,

  You insert P4_SELECTED_VALUE value in the APEX session before refreshing the report.

  Add following the JS function in your page

  //insert value into session using JS
  
  function fnSetSessionState(pItem, pValue) {
      var vAjaxDummy = new htmldb_Get(null, $v('pFlowId'), null, 0);
      vAjaxDummy.add(pItem, pValue);
      var vDummy = vAjaxDummy.get();
      vAjaxDummy = null;
  }
  

  and your code...

  $('div.tree li a').click( function() {
  
  node_id = $(this).parents('li:first').attr('id');
  
  if (node_id.substr(0,node_id.indexOf('|')) == 'Y')
  {
  $s('P4_SELECTED_VALUE',node_id.substr(node_id.indexOf('|')+1));
  alert('Value Set: ' + $v('P4_SELECTED_VALUE'));
  fnSetSessionState('P4_SELECTED_VALUE',$v('P4_SELECTED_VALUE'));
  //$a_report('28576803999973770','1','20','20');
  $a_report($v('P4_REPORT_ID'),'1','20','20');
  };
  });
  

  That's how I used the version 3.2 or earlier. But now I prefer to use declarative dynamic actions...

  Kind regards

  Bind variables are evaluated when the cursor is opened. Not when extract you the data.
  I don't know why you use dynamic sql, here, you do not need.
  In any case, your code is incorrect.
  Assuming that the client_id is unique, Yes, your fetch fetch one line. When you loop the second time, retrieving a new record for the same statement, then you hit no_data_found.

• How to get the value of a variable to bind a client method of the AM?

  Hello
  
  I have a VO based on a variable binding. This binding variable is associated with an element on the page. When the user fills the element that the binding variable is written, the query is executed. This method works.
  What I want now is the following. With a second button, the user runs an exported AOS action method. In this method, I want to get the value of the binding variable that has been put forward.
  How would I do that?

  You can get the variables bind currently set on the object view as follows:
  catServiceDurationsVO has the reference to the VO
  VariableValueManager vm = null;
  VM = catServiceDurationsVO.ensureVariableManager ();
  System.out.println (VM.getVariableValue ("BindVariable"));

• How many times can I use a variable binding in a query of the VO?

  Is it possible that I can use a variable binding in a query of VO just once?

  I test a query that keeps throwing the Houston-27122 error by pressing the application module tester. I tried to limit the problem to the simplest possible case, and it seems that the error is caused by the fact that I use the same variable bind two or more times.

  When the query looks like this:

  

  I have run, enter 'x' and it returns me the result.

  When I change to:

  

  I have run, enter the value

  

  and immediately get the error

  

  The same thing in sqlplus runs without problem:

  

  My version of JDev is build JDEVADF_11.1.1.9.0_GENERIC_150314.0718.6673

  Please, advise.

  P. S. where can I find documentation queries are supported in your? In particular, I'm interested if I can use WITH the clause. There seems to be some confusion on this matter (see, for example, Oracle SQL WITH clause support - JDeveloper and ADF)

  Thank you.

  It depends on:

  Open your VO in JDev and go the the query page.

  In the lower part, there is a drop down 'link type', it is usually set to "JDBC-positional. In this case, you will need to provide the bind value for each occurrence of the variable binding separately.

  You could change that to "named" (don't remember the exact name). But beware, this will also affect all relatioships master retail to others your. I think that this is not a good idea to change the style of binding to a single VO.

  Good bye
