Definition of variables bind to VO JUnit test cases

• 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

• Persist does not throw an exception in a JUnit test

  I implement a JUnit test by using Toplink JPA provider. I must be missing something because I try to keep twice the same entity and no exception is thrown. PersistenceException, nor any other type of exception. The code can not be easier:
  
  
  @Test
  Public Sub testAddExistingTeam() throws Exception {}
  
  Team = new Team ("team2");
  
  try {}
  
  EntityManagerFactory emf =
  Persistence.createEntityManagerFactory ("Fisher");
  EntityManager em = emf.createEntityManager ();
  
  em.getTransaction () .begin ();
  
  EM. Persist (Team);
  EM. Persist (Team);
  
  em.getTransaction () .commit ();
  EM. Close();
  }
  catch (Exception e) {}
  e.printStackTrace ();
  }
  
  }
  
  Note the two em.persist (team).
  
  This code does not enter into the catch block or produce any kind of exception. On the other hand, I checked after the first
  EM. Persist (Team); the team is really successful.
  
  The relevant parts of the team following class definition:
  
  @Entity
  @Table (name = 'TEAM')
  Team/public class implements Serializable {}
  @Id
  @Column (name = "NAME")
  private String name;
  
  @ManyToOne
  @JoinColumn (name = "CLUB_NAME", referencedColumnName = "NAME")
  Club private;
  category private;
  private String email;
  
  @ManyToMany (mappedBy = "teams")
  list < competition > competition private;
  
  
  public Team (String name) {}
  myIdName = name;
  This.Club = null;
  This.competitions = new ArrayList < competition > ();
  }
  
  more than builders...getters/setters...and.
  }
  
  I'm really intrigued by this problem. Could someone help? I would be really grateful!

  This is expected behavior as persist is a no - op if called on one managed entity (other than to the waterfall on relationships with cascade. Persist), and the first call to persist makes the past in team managed entity.

  Try calling em.flush (); and em.clear (); between calls persist to get an exception.
  The first flush will ensure that the team is inserted into the database, while that clear it peel while the second call persist will attempt to insert the team. JPA providers should not throw the entityExistsException persist - it can be delayed until the transaction either emptied or committed, then you are likely to get a PersistenceException validation instead of EntityExistsException to persist.

• 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");

• 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.

• How to use a variable binding in an IN clause

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

  select *
  from test
  where test_column in (:bindVariable)

  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?
  
  Thanks in advance.

• 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

  If not check this: http://www.jobinesh.com/2011/03/initializing-bind-variables-in-query.html

• JUnit Test Suite Limitations on the number of test classes can be included in the suite

  I run JUnit tests on my ADF Model picardalice in an application. I'm getting an instance of a request through the class of the device module and it helps in my test classes. It was created using all the Test Suite of Business components in JDeveloper 12.1.3.

  I'm running a JUnit test suite and it has several test classes in its operation. It runs successfully some and others fail. If I run those who fail by themselves, they are successful. If I remove the test classes in the suite they work (even those who have failed when the test classes were listed as a result of tests).

  Here is my code for the test method.

  @Test

  public void testAccess() {}

  See ViewObject = fixture1.getApplicationModule () .findViewObject ("ProjEstimateDtlVO");

  assertNotNull (view);

  }

  the ViewObject perspective comes return null for the execution of the test suite during all test classes are ran. It's successful return if I run one test case. It's successful return if I remove test classes in the following before running the suite.

  There are 70 + test classes in the suite. Is there a limitation on the number of test classes that must be executed in a test suite? Is it because it is repeatedly using an instance of the application module? Is this other thing?

  Everyone ran through this?

  Thank you.

  The problem in my case was because in one of the test cases I was releasing the module of the application in the method of disassembly. Since the application module was created once again, when I ran after tests and he ran this test scenario, anything after this would fail due to no application being created module.

  Thanks, Timo

• JUnit test of an ADF application when you have nested application modules

  Hello

  When you set up a device for JUnit test in the model of the ADF, and you have nested application modules, there are advised to have a class of the device for each module of the application, or create a luminaire of class for the root application module and access somehow nested those there for view objects you want to test JUnit , or have a luminaire of class and somehow reference the individual nested application of this class modules? Everything I've read about JUnit test of an ADF application only shows an application module in the template project.

  Thank you.

  I have used with success that one category of luminaire for my application module root, and then in my test case files I can reference the application embedded this suff module.

  Example:

  The TestAMFixture.java file is where you describe the application module you want to use. This file and others, is what is generated when you let JDeveloper create your Business Component Test Suite (chosen from the New Gallery):

  The constructor of this file is where the application module is defined:

  public TestAMFixture() {}

  _testAm = Configuration.createRootApplicationModule (amDef, Config);

  }

  In my test for the projectVO scenario file, I'm testing a required attribute in a display object, so I need to access the view object that is in a nested application module:

  ViewObject _projectVO = fixture1.getApplicationModule () .findViewObject ("ProjectAM1.ProjectVO1");

  fixture1 is a reference to the TestAMFixture class. getApplicationModule() is a method in this class that returns the application root module I set in the TestAMFixture constructor. ProjectAM1 is the nested application module and ProjectVO1 is the view object where the attribute is that I will test.

  For a better explanation, please see these references, I used.

• 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.

  I will highly recommend to read other links below:

• Flight to record a JUnit Test creation

  Hello

  (also published in https://forums.oracle.com/community/developer/english/fusion_middleware/application_server/jrockit that is the link to the forum on JRockit Mission Control)

• 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
