• Get the bind variables name string SQL or the cursor

  Hello
  
  Is there way to get of the bind variables name string SQL or the cursor?
  
  Example of

  DECLARE
    l_sql VARCHAR2(2000);
    desctab DBMS_SQL.DESC_TAB;
    curid   PLS_INTEGER;
  BEGIN
  
    l_sql := 'SELECT * FROM emp WHERE mgr = :X and deptno = :Y';
  
    curid := dbms_sql.open_cursor;
    dbms_sql.parse(curid, l_sql, dbms_sql.NATIVE);
    ....
  END;

  What I mean with the SQL string:
  I love to get using some functions from above code variable l_sql all the bind variable.
  In this case the function should return array where is for example: X and: Y
  
  Back to bind the cursor variable names, I mean same but rather string I pass number of cursor.
  
  Y at - it sucks ready function or some may share a code customized for this purpose?
  
  Thanks
  
  Kind regards

  I found there are wwv_flow_utilities.get_binds of the function not documented in APEX packages that do what I want.
  Usage example

  set serveroutput on
  DECLARE
    binds DBMS_SQL.varchar2_table;
  BEGIN
    binds := wwv_flow_utilities.get_binds('select :P1_TEST from dual');
    FOR i IN 1 .. binds.count
    LOOP
      dbms_output.put_line(binds(i));
    END LOOP;
  END;
  /
  
  anonymous block completed
  :P1_TEST

  But I would not use these functions without papers as those who can change or there is no future versions APEX.
  Is there a documented function or the custom function that do the same thing as wwv_flow_utilities.get_binds?

  Some old basic example code of my friends. Also the media getting the bind variable of PL/SQL code blocks anon.

• 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

• The value of variable binding VO on page load by program

  Hello everyone!

  I use JDeveloper version 11.1.2.3.0

  I am currently trying to get the filtered data to a VO, based on a WHERE clause with a variable binding. This process must be done on the loading of the page. I have set this variable for liaison with the id of the logged in user (the part to get this id is already reached and used somewhere else). My current approach is to define a bean managed with scope pageFlow. Inside of this, I have a method in which I get the id and I put it as parameter. The code snippet:

        BindingContainer bindings = getBindings();
          OperationBinding operationBinding = bindings.getOperationBinding("getUserIdFromUsername"); //getUserIdFromUsername is a method defined in the AppModule and exposed in the client interface
         operationBinding.getParamsMap().put("username", getUserName());
        Object userID = operationBinding.execute();
          setUserId(Integer.parseInt(userID.toString()));
         System.out.println("THE USER ID IS: "+getUserId());
         BindingContainer bindings2 = getBindings();
         OperationBinding operationBinding2 = bindings.getOperationBinding("ExecuteWithParams");  // i've dragged and dropped the ExecuteWithParams operation into the page
         operationBinding2.getParamsMap().put("userId", getUserId());  // userId is the bind variable which i'm talking about
          Object result = operationBinding2.execute();
  
  
  

  Then I call this method on BeforePhase in the view of the page. It works, I get the filtered data and the println shows me the correct ID. The problem is that whenever I select a row in the table showing the data, the page seems to reload and it always reload the selection at the forefront.

  What I am doing wrong? Maybe this isn't the right approach, that I saw a few other posts on this topic, but they are not very clear to me.

  Please advice

  OK, that's what I did. I created the method to set the value of the variable to bind to the query of the VO in the AppModule instead of inside the bean (this method also runs the query) and client presentation to the interface. After I have created the method call in the section of links the pagedef (where he gets the value of the id of the bean in the original post), and followed Cvele_new_account suggestion, calling the method as follows:

  RefreshCondition = "#{! requestContext.postback and empty bindings.exceptionList}" / >

  Thank you for the help guys!

• Setting value to a variable binding

  Binds the values of variables can be access with this:
  
  AttributeBinding deptBinding =
  (AttributeBinding) getBindings () .getControlBinding (bindName);
  Return deptBinding.getInputValue ();
  
  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");
  attr.setInputValue ("test");

• Display Variable binding object, query, (Bean.attribute) HOW?

  Hi, I use an attribute of bean as a Bind Variable in a query to a display object.
  I have the following bean:
  

  package model;
  
  public class FalseBPM {//Simulate a BPM payload
      private String idDocIPM;
  
      public FalseBPM() {
          idDocIPM="5.IPM_016801";
      }
  
      public String getIdDocIPM() {
          return idDocIPM;
      }
  
      public void setIdDocIPM(String idDocIPM) {
          this.idDocIPM = idDocIPM;
      }
  }

  In a fragment of web page, I have an af:table of the DB (by datacontrol). It is necessary that the table load only the lines with the idDocIPM in his ID_DISTRIBUTION column. I did this:
  In my view, object-> query:

  SELECT IpmDistributionManual.ID_DISTRIBUTION, 
         IpmDistribucionManual.ID_BUSINESS, 
         IpmDistribucionManual.ID_CHANNEL, 
         IpmDistribucionManual.ID_ENTITY, 
         IpmDistribucionManual.VALUE
  FROM IPM_DISTRIBUTION_MANUAL IpmDistributionManual
  WHERE IpmDistributionManual.ID_DISTRIBUTION=:ID 

  In my display-> query object: - > variable binding:

  <Variable
      Name="ID"
      Kind="where"
      Type="java.lang.String"
      DefaultValue="#{falseBPM.idDocIPM}"/> //But I get an error in Literal or in Expression mode.

  How can I do this?
  
  Thanks in advance.

  Sarah,

  In your workflow, drag and drop the action 'run with the settings' for your view object (it is in the range of data control) on the workflow as a method call activity. Bind the parameter to the value of bean with EL (that you have tried to do in the VO itself - note that you can not use EL in the template like this project). Then, make sure the method call is wired to the top to run before your activity in the workflow view.

• 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.

• Variable binding and View object to filter the results of ADF table

  I created a view ADF object where I compare "USERID =: USER_ID" in sql. I created a table with this ViewObject on a .jspx page.
  
  I use the following code in the support to the Bind Variable has a value:
  
  
  String uidregAMDef =
  'mil.navy.comfisc.uid.toolkit.model.UIDToolkitModule ';
  String uidregConfig = "UIDToolkitModuleLocal";
  
  Check out the module
  UIDToolkitModuleImpl = uidAM
  (UIDToolkitModuleImpl) Configuration.createRootApplicationModule (uidregAMDef,
  uidregConfig);
  
  ViewObject vo = uidAM.findViewObject("CurrentContent1");
  vo.setNamedWhereClauseParam ("USER_ID", 2);
  
  vo.executeQuery ();
  
  Configuration.releaseRootApplicationModule (uidAM, true);
  
  
  Returns a null value.
  }
  
  
  
  The result I'm looking for is the TABLE to refresh after that code runs to just display the values where the: USER_ID = 2
  
  
  However, the table does IS NOT refresh... I do not get a runtime or compile... errors but the picture is not updated, even if the setNamedWhereClauseParam seems well.
  
  
  
  Any suggestions? The original Version should not update with the setNamedWhereClauseParam?
  
  
  Thank you

  Hi John72

  In your case is more recommended the use of the method of the page definition and iterator, you can add the filter to your page just definition method drag and drop the ExecuteWithParams method as a button of operations in your jsp/jspx page, in the page definition are created automatic ExecuteWithParams and var bind method, you can now create an action of your button and add the following code :

  public String commandButton1_action() {}
  DCIteratorBinding iter = (DCIteratorBinding) bindings.get ('variables');
  iter.getBindingContainer () .getVariableManager () .setVariableValue ("MyVar", "value");

  execute the method

  BindingContainer links = getBindings();
  OperationBinding operationBinding = bindings.getOperationBinding("ExecuteWithParams");
  Object result = operationBinding.execute ();
  If (! operationBinding.getErrors () .isEmpty ()) {}
  Returns a null value.
  }
  }

  Good luck

• Variable binding defined in LOV

  Hi, I use JDev 11.1.1.7

  I have a VO (FundingNameVO) which takes in bind variable.

  FundingNameVO is used as LOV in an another VO (ProjectVO) for a FundingName attribute.

  ProjectVO also has an attribute FundingSource has also a LOV.

  When FundingSource is selected, the value must be sent to the liaison FundingNameVO variable to determine the LOV to display for FundingName,

  How to pass the FundingSource value to the variable of FundingNameVO binding?

  Thank you.

  Hello

  If the value of the variable binding from attribute ProjectVO follow these steps:

  in tab display accessor is ProjectVO, you have added an instance of FundingNameVO, click the view accessor on Edition, then in the open Panel, you see the bind variable, set the value of the variable binding with the good ProjectVO attribute name

• 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

• Reg: Cardinality Feedback for queries with variable bind

  Hi all

  One of my query (having no bind variables) takes a lot of time (10 minutes) to run for the second run.

  I came to know that its due to the feedback of the cardinality.

  I disabled _optimer_use_feedback for help and the query has been run within 2 seconds.

  If I disable _optimizer_use_feedback at the instance level, is there a problem for queries with variable bind?

  > Sorry! I'm not suppose to disclose the NAMES OF THE TABLES

  OK, no problem and I take this restriction as a chance to learn what is cardinality comments, and similar expressions.  Now, since you can't explain post program for our help, I would try to explain what is comments of cardinality and similar expressions: (since you did not mention Oracle version, so I guess it's 11.2.0.1)

  In the Oracle 11.2.0.1 database some SQL statements returns significantly different lines i.e. for some SQL statements earlier execution plan there are has 100 lines by optimizer in the first plan of execution and, where the same SQL statement executed, based optimizer 1000 lines.  This happens because of several cursors for child for a single SQL statement and change bind peeking, collection of statistics, characteristic of re-optimizing 11.2.0.1, permission to referenced objects, ACS (Adaptive Cursor sharing) etc.  The preaching of changes to lines due to above reasons as well regarding also the SQL statements that are not contains the variable i.e. AKA vibration cardinality of liaison function.

• How not to display variable binding in the query ADF search panel?

  Hello, I use JDeveloper 11.1.2.3.0.

  I have a variable binding in my VO, (* required) that I use in the sql query. I put the value of this variable to link through the groovy expression so I don't have to manually put through my page. It works fine but the problem is that it appears in the query ADF Panel that I created in my page. To do this, I created a ViewCriteria and I've specified to display only 3 (other) fields for the simple search. Apart from the selected 3 variable bind shows here again because its value is set. I tried to remove the ' * required ' of the variable binding in the original Version, but in this case I have problems with my sql query.

  Does anyone know how this variable is not to display in the Panel request ADF?
