• 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

• 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

• Bind Variables out of use

  I don't know where to post this, please point me in the right direction if necessary. It seems that binds the variables in the order that they appear in the SQL statement works very well, but bind them down causes the statement to be poorly executed. Here is the result on my machine, Win 7 Pro, JDK 1.7.0_21 against Oracle 11.2.0.3 on Linux 64.

  Although what do you expect to link which includes a colon in the name?

  cs.setInt(":a", 10);
  

  And the code like this

  cs.setInt("a", 10);
  

  is NOT supported. You can not bind by name using the setXXX methods.

  Change your code to use syntax supported, and you shouldn't have a problem.

  cs = c.prepareCall("select * from eric_example where a = :1 and b = :2");
  cs.setInt(1, 10);
  cs.setInt(2, 50);

  >
  Binding parameters named

  Binding by name is not supported when using the setXXX methods. In certain circumstances, previous versions of the Oracle JDBC drivers have allowed binding variables name declaration when using the setXXX methods. In the following statement, the variable named EmpId is linked to the whole 314159.

  P = conn.prepareStatement PreparedStatement
  ("" SELECT name FROM emp WHERE id =: EmpId "");
  p.setInt (1, 314159);

  This ability to set by name using the setXXX methods is not part of the specification, JDBC and Oracle does not support. JDBC drivers can throw an SQLException exception or produce unexpected results. From JDBC Oracle Database 10 g drivers, connection by name is supported by using the setXXXAtName methods.
  >
  You can use one of these 'previous versions' driver which seem to confirm the connection by name but these links are NOT supported, so you should not try to use them.

  There is no work around. Replace the names of variables bind with an exclamation mark.

• Correct way to use Bind variables when you use an interface to MS SQL Server

  Hey,.
  I have some difficulty to find how to use bind variables in a view, when you use an interface to MS SQL Server. For some reason when I use an ApplicationModule who has a library of MS SQL Server JDBC loaded and I try to click on OK when you change the following query:
  
  SELECT kit_status, component_id
  OF numbered_inv
  WHERE trialname =: 1
  
  I get an error stating that ' SQL Query Error Message incorrect syntax near ':'. JDeveloper is compatible with SQL server for bind variable as this query works fine if I replace the: 1 with a Word to say "Test test".
  
  Thanks in advance

  I'm trying to use a variable binding in an IN clause where the column is a type varchar2. Something like:

  I tried the assignment of channels bind variable separated by commas (for example, test, test, test) and separated by commas strings with quotation marks (for example. 'test', 'test', 'test'). None of these work. Anyone know the correct way to do this?

• 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 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

• 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!

• 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?

  Thank you

• How to remove the variable created when using definedNamedWhereClauseParam()

  Hello
  
  My Jdev version 11.1.1.7.0.
  
  I'm Executive where clause programatically where I need to bind two bind parameters under certain conditions. Example, I have two bind variables X, Y.
  
  Here's the problem:
  
  Assume that the first time I'm setting one variable X, so I define X bind variable and execute the query.
  
  What second time I send only Y but not X. In this implementation of the scenario of VO throw an exception, given that the variable X is already created in the VO object and where clause does not have this setting.
  
  So how to remove variables created in the original Version all in definedNamedWhereClauseParam(). I need to erase what ever the previously created variable every time I execute method.
  
  I can make the similar functionlity using setWhereClauseParam (using literals). But I have a few technical restrictions for use.
  
  Could you please help me how to remove the variable before vo using definedNamedWhereClauseParam.

• Definition of variables bind to VO JUnit test cases

  Hello
  
  I use Jdeveloper 11.1.2.2
  
  I have a problem when writing to VO to JUnit test case.
  For the Remove method in the Test case, I spent variables in the t by using a setWhereClause().
  Like this:

          view.setWhereClause(null);
         
          String whereClause = "location_id = '" + newUpdatedLocationId  + "' AND organization_id = '" +newOrganizationId + "'" ;
          view.setWhereClause(whereClause);
         
          view.executeQuery();
          
          while (view.hasNext()) {
              view.next();
              view.removeCurrentRow();
          }
         
          fixture1.getApplicationModule().getTransaction().commit();

  But he demonstrated a a mistake as the bind variables are not defined.
  
  So, how do I access variable Bind programmatically and set the values?
  
  Thank you

• 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 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:

  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.
