• ADF: Re-apply the where condition of a view object and updating table

  Hello
  
  I have a table for documents, with columns for the title of document, document type and so on. There is also a column called "receiver".
  In the viewobject based on the table, I have a condition that only the lines where the receiver is null should be included. In other words: only documents unassigned should be indicated in the table.
  
  The purpose of the page that contains the table is to assign documents to the receivers. The idea is that the user enters a name in the column of a receiver or several lines and then press a button of validation.
  When a line - a document - has been assigned to a receiver and the change is committed, this line is more fills the where of the viewobject condition and I would like my page to reflect the fact that. In other words: as soon as one or more lines have been assigned to a receiver and the changes are committed, the lines should disappear from the table and the page.
  
  What is the best way to achieve this?
  
  Kind regards
  Andreas

  To do this is to add a navigation case to the same page and use this case to navigation after validation. Should run the query again, it costs you a full page sent.

  Another way to do the validation and the use of a managed method bean to re run the iterator.

• The attributes defined for SelectCheckbox in the view object Failed

  Hello

  I expanded the view object of the table to filter the records and the table contains the selection box (no change has for this box). When I choose one of the records to help select the check box and go to an action, the error is coming as "Attribute defined for SelectCheckbox in the view object TeamTableVO failed" ... Is the error due to VO scope or any other reason...

  Help, please...

  Hello..

  Check the following

  1. check if the value of any attribute is set, if yes remove

  2. check the attribute map

  3. set your columns can Yes

  4. check if its VO selected to interview

• Whether the object is a table, view, or synonym

  In our database, there are a lot of tables/views which have similar fields. I get confused about which is which. In addition, there a lot of synonyms. Are there sql commands to check where an object is a table, view, or synonym for a table/view? If it's a view created from a view, I would like to trace through the hierarchy and find root tables which provide the data.
  
  Thank you very much.

  Check DBA_OBJECTS to the name of the object type. For synonyms, you can check DBA_SYNONYMS and point of view, you can see DBA_VIEWS.

• AF:table does not display the records to make the updating of the view object iter

  Hi Experts,
  
  I use JDeveloper 11.1.1.4 and I have a page that shows a view object records one particular reading as an af:table. When I run the page to everything first he shows all the data at all. But there are 2 folders when I run the query that only read the view object. In my page there is a link called "Refresh" which calls the operation "Execute" in the view of my view object iterator. When I click on this link the table shows two records. Why the table shows no files once when the page is rendered?
  
  Please help me.

  Hi user,

  Yes use component query to display criteria. Please let me know if something specific I need to check when I use the query component. If you have already faced this problem please help me to solve it.

• Table of the ADF and shape ADF on the same view object

  Hello
  
  According to ADF demonstrations available on the website of the ADF, I created a jsf with 2 panels page. A Panel is an ADF table based on a display object. The other Panel is and ADF form based on the same view object. My requirement is that I scroll the records in the table of the ADF, the shape of the ADF should dynamically display the details of the record in the table of the ADF. My understanding is that this should be automatic. However, its does not work as expected. What did I miss?

• View usage type lookup does not match the object list definition drop-down display

  can someone tell me why this error could be coming:
  View usage type lookup does not match the object list definition drop-down display
  
  Thank you and best regards,
  Amrit

  Hello
  seems that in your choice list item (probably call him messageChoice), you are defiining of these properties of the list view definition and the choice list view instance.
  You must provide one. If your choice list values to all users (i.e. the vo behind the choice list has no dynamic where clause or the query), then use choose list definition property. If each user sees different options in the drop-down list (i.e. dynamic where clause for vo), use the property of the lookup instance.
  In the definition of choice list, give the fully qualified name of the vo.

• View object has more than 2000 lines but with only 500

  Hi all

  I have a view object that has more than 2000 lines. But when I try to see the front end of data, it does is display only 500 records.

  Then when I did some research I discovered that there is a profile option where I need to increase the size.

  before the value in the profile Option (FND: display object Max size Fetch) amounted to 500

  Thus valued at 3000.

  But I wanted to know what will be the impact of the evolution of this profile option on Database/Application.

  
  

  Please advice which would be the best way to manage several size maximum extraction on the objects in view.

  Thank you.

  Not really sure what you mean by 'calculations are performed properly"If you are not able to see in the front.

  If you don't even have an option "next/previous" on the table to go to the next round?

  You can paste a screenshot?

  You can try to increase the property records of the region of the table and see what happens?

  Where did you add vo.setMaxFetchSize(-1)?

  Can you try replacing exwcuteQuery() and add the following inside that?

  See you soon

• Stop the automatic execution of the View object without setting to insert only?

  Hello

  I have a View object that is used to insert only.  However, as I have to be able to filter through the lines not validated with a view criteria, I can't put the View tuning object to insert only.

  I do not want to run queries to the database because the attribute I am filtering by is a transitional attribute that is set when a new line is created.  The only purpose of this attribute should be used for filtering.  When my VO runs a query, I get an error because this attribute is not in the table of database mapped to the VO.  Currently, this attribute is added to the EO and I added it to the VO as attribute 'of the entity.  Another reason, I want to query the DB is because there are more than 500 k rows in the table.

  In short, I need a way to stop all the display object queries until I called the line below but I can't adjust the View object to insert only.

  welltdwVO.setQueryMode(ViewObject.QUERY_MODE_SCAN_UNPOSTED_ENTITY_ROWS);
  

  Thanks for reading.

  Hello

  First keeping a transitional attribute at the level of the entities should not raise an error make sure you follow the instructions.

  http://docs.Oracle.com/CD/E21764_01/Web.1111/b31974/bcentities.htm#BABHGCAH

  Secondly, to prevent the execution of the query you can run together of empty lines on the view object, before displaying the page. If an iterator is involved, and it doesn't have to be so also on the property of RowCountThreshold-1.

• ADF BC to SQL Server connection with variable set to View object

  Hello world
  
  I develop a BPM Application using Oracle BPM 11.1.1.5.0 and JDeveloper 11.1.1.5.0
  
  Following the thread of the link below, since it is a new topic, I decided to open a new thread.
  
  Re: ADF method call to extract data from DB before loading the page from the initiator
  
  what I try to do is to get a record from a database and show to the user on the initiator of the UI using ADF BC and not the database adapter.
  I have worked with ADF BC and display objects to get all the lines and show them to the user in a table.
  
  However, when I try to run the same query in the parameterized shape just return a single line, I hit a wall.
  In short, my problem is like this:
  
  I have an Application Module which has an entity object and a display object.
  My database is SQL Server 2008.
  When I try to create a new read only view object to return a single line I face the problem.
  The query that I have in the section my display object query is like this:
  

  select *
  from dbo.Employee
  where EmployeeCode= 99

  which works very well.
  However when I set a variable input_code, linking for example and change the query as follows it won't validate.
  

  select *
  from dbo.Employee
  where EmployeeCode= :input_code

  He just telling me
  >
  incorrect syntax near ': '.
  >
  I don't know if this has to do with my Oracle DB is not or I'm doing something wrong.
  Can someone help me with this you problem?
  
  Thanks in advance

  The problem is that you are using 'Oracle named' style for the binding of parameter in the SQL statement. However, this style of binding is specific Oracle. You must use "Positional JDBC" style of binding with MS SQL Server:

  select *
  from dbo.Employee
  where EmployeeCode= ?
  

  (The style of binding is specified in the query to the dialog box Definition VO Editor pane).

  If you specify the positional style of binding "JDBC", another field called 'Linking the Positions' will appear in the definitions pane variables bind VO. You will be able to specify it is the position of the particular parameter in the binding variable VO query bound to. (the position of the bond index is 0-based).

• Vs DB view view object

  Hello
  
  Can someone explain the differences and/or the benefits of creating a view in a database against the creation of a view in an ADF web application object? I understand that the maintenance will be different.
  
  I wonder if there are benefits to creating a display object based on multiple entity objects that relate to the tables, from the creation of a view object that function object an entity associated with a view in the DB?
  
  Can someone please explain?
  
  Thank you

  I understand, but y at - it an advantage to create a view of DB, rather than in the application? I'm thinking about one, and I can't think of anything, except that maybe the point of view could be easier to maintain if it's a view of the application object.

  Use ADF (links, ADFBC and Application Module) anyway you must create a View object, or it is based on a view or table

  Benefits of DB view is you can use it in your applications for example, ADF, APEX, FORMS. but views based on a single table does not have these benefits other than to hide some columns of the developers.

  It will be useful,

• level of access to the lookup table

  I use Dreamweaver CS4. It seems that access levels can if apply (at least through server behaviors) to a field in the same table that host users and their associated passwords. I adopted a database that contains a table that contains the users and their passwords and access levels are stored in a lookup table. Outside hand coding this or the change in the structure of the table to include levels of access, users and passwords in the same table, can anyone provide an overview on how to handle this?

  > I do not understand the recordset has to do with the newspaper to the user.

  Yes, I have just answered the same time-I got deceived to have first to create the Recordset. Your version of MySQL does support the views?

• Normal rewrite of query with views of database

  Hi all
  
  I'm trying to make my programmer life easier by creating a view of database for them to query the data, so they don't have to worry about joining tables. However, query rewriting does not work no matter how I set the MV and the view. Here is an example:
  
  I have the Sales tables with columns: amount of the update, CustCode,.
  
  and the Customer table with columns: CustCode, CustDesc
  
  I create a SALES_V view with columns: update, CustCode, CustDesc, amount by joining the Sales table with the Customer table as follows:
  -----
  create or replace view SALES_V as
  Select Update, c.CustCode, c.CustDesc, amount
  s sales
  Join customer c on (s.CustCode = c.CustCode);
  -----
  
  In the interest of speed, I create a materialized view SALES_TOT_MV with columns: update, with the following SQL:
  -----
  create a materialized view SALES_TOT_MV
  activate the query rewriting
  What to choose PDate, flat amount from the sale
  Group update;
  -----
  
  When I run the following query, I expect to be rewritten to use SALES_TOT_MV:
  -----
  Select updating, flat SALES_V
  Group update;
  -----
  
  However, to explain the plan to always tell me that he uses the table SALES , not the SALES_TOT_MV.
  
  Can someone tell me this is a limitation of the Oracle optimizer or am I missing just something for this?
  
  Thanks in advance!

  That sounds like a horrible idea. I say this because you will find yourself finally with programmers who know nothing about your data model and how to interact properly with it.

  In addition, what you will get is a developer who uses one of your views and see 20 columns inside, there 4 it needs. If all these 4 columns comes from a 2 simple table join, but the view has 8 tables, you lose a ton of resources using the view (and God forbid that they should join this view to another view to get 4 of the 20 columns of this other view as well).

  Ideally, you should write stored procedures that satisfy exactly what is needed (if you are the resource database and these other java programmers, .net, basic etc...) and the front-end developers call these routines customized for a specific object.

  Creating views is not bad, but it is not an appropriate solution that developers not learn or understand SQL or the data model.

• Panel of the ADF does not variable defined in the ADF view object.

  I created a group of ADF, which allows the user to run some simple queries against a database of Oracle is using the view objects ADF and ADF view links and ADF application module.
  One of them asks detailed information of research on a database object (Table, view, or other) to dba_objects. SQL uses a parameter (: P_OBJ_NAME) which has a default value of "departments". If I run the ADF application by herself outside the ADF panel module, everything works fine, he invites me to provide a value for the parameter: P_OBJ_NAME.
  As I said the Panel contains various links to view ADF which one who must prompt the user to provide a value for: P_OBJ_NAME. When I run the Panel he does not invite me to: P_OBJ_NAME, it only uses the defined default value "departments".
  I hope that I have described my problem for everyone to understand. Of course, the question is how to make the Group ADF to prompt the user to provide a value for the parameter: P_OBJ_NAME, my waiting has been the sql of the view object and request module, both are designed to enter a value for this parameter, then the Panel should do just that, but it's not.
  
  Expert you would be most appreciated.
  Thank you.

  The instigation of a parameter is a feature that we have built in the ADF Tester - is not a default behavior that you get in your application when you have just placed a VO on your page.
  To get something like that spend the operations under the VO node in the data control palette and drag the operation "Run with parameters" to your page to drop it as a form of parameter.
  This will give your user name a place to complete the setting, then press a button to run the query.

• If a view object query returns no rows, can the vacuum to be tested at all?

  All those who know or have also experienced:
  
  I guess that the answer should be Yes, but I tried anyway, I still didn't worked. Here is the code (it's a method behind a command button, a bean of support (I use JDeveloper 10.1.3.4).) In the code, LoggedInStudent is the name of a view object; ZBLCModule is the name of the application module):
  

      public String commandButton1_action() {
          FacesContext fc = FacesContext.getCurrentInstance();
          ValueBinding vb = fc.getApplication().createValueBinding("#{data}");
          BindingContext bc = (BindingContext)vb.getValue(fc);
          DCDataControl dc = bc.findDataControl("ZBLCModuleDataControl");
          ApplicationModule am = (ApplicationModule)dc.getDataProvider();
          ZBLCModuleImpl zblcam = (ZBLCModuleImpl)am;
          LoggedInStudentImpl studentsFound = (LoggedInStudentImpl)zblcam.getLoggedInStudent();
          
          String navCase = null;
          
          // Test (1): if the view cache is empty; always bombs up the application if it IS empty:
          if(studentsFound.getAllRowsInRange().length == 0) {
              navCase = "userNotFound";
          // (2) The following three tests gets to run only when the cache is not empty; they work fine.
          } else if (((Number)studentsFound.first().getAttribute("HoursAttm")).floatValue() == 0.0) {
              navCase = "noHours";
          } else if (((Number)studentsFound.first().getAttribute("Balance")).floatValue() > 0.0) {
              navCase = "notZero";
          } else if (!(studentsFound.first().getAttribute("Validated").equals(" "))) {
              navCase = "validated";
          } else {
              navCase = "zeroBal";
          }
          return navCase;
      }

  When the view object query returns a line, the whole of the application works without error. When the query returns no rows, test (1) always bombs toward the top of the application, prompting a Houston-30003 error.
  
  (1) test, I tried the following:
  

    if (studentsFound.getAllRowsInRange().length == 0)
    if (studentsFound.first() == null)
    if (studentsFound.getEstimatedRowCount() == 0)
    if (studentsFound.isDead()) //I do not know what isDead() does; just tried desperately.
    if (studentsFound.equals(null))
    if (studentsFound.getCurrentRow() == null)

  With each of these events, I got an error of Houston-30003. It does not matter what looks like the conditional test; It is important only when the objects from view cache is empty. If the view cache is not empty, everything, including the test (1), works very well. And when the cache is empty is not because of the failure of the connection to the database, but because the student is not in the data table and line are for the student.
  
  It is a requirement of the company to do something when the view object query returns no rows. Can it be tested at all? How?
  
  Or is there something wrong in the first lines in the method before the {color: green} String navCase = null; {color} line?
  
  Thank you very much for your help!

  Hello

  What you have done, is to get a handle to the object that CAN execute queries to the database.
  However, you do not query the database.

  Just add:

    LoggedInStudentImpl studentsFound = (LoggedInStudentImpl)zblcam.getLoggedInStudent();
    //New line
    studentsFound.executeQuery();
  

  The code that Shay has given you is when you do not have a request for all module, but since you are talking about a command etc button I guess that the module of the application is already active.
  The line I gave you should be enough to make it work.

  I'd be careful with the

  studentsFound.hasNext();
  

  I suggest to use estimatedRowCount();
