• Dynamic SQL query to get the unique value of list in a column

  I have two tables: tblWorkers and tblSkills. tblWorkers has a column, skills, which is populated by a field of multiple-checkbox with one or more skill_IDs of tblSkills, so each tblWorkers.Skills consists of a list of one or more comma-delimited values. For any Skill_ID, I need to generate a list of all workers with the appropriate skills, so I tried to do something in the direction of SELECT WorkerName FROM tblWorkers WHERE IN of skills (skills, #FORM. Skill_ID #)... or WHERE skills (ListFind (skills, #FORM. Skill_ID #))... etc.? My results (once I have had data type mismatches of the road) return all workers, not just those with the desired skills. There must be an easy way to do... How people with a little more experience CF/SQL I do this?

  > each tblWorkers.Skills consists of a list of one or more comma-delimited values

  This is your problem. You store a list of values that you want to access power/query separately in a single column. You will have to burst in a separate table.
  TblWorkers

  TblSkills

  TblWorkerSkills
  mapping table of many workers with skills.

  If you do not change your data model now, you will constantly be butting your head against that.

• Get the old value of the element when sending, why?

  I am looking for the value of the newly submitted to the building of a controller method.  However, the previous value is obtained, not the new value that is entered in this area before submitting the page, and I don't know why.

  	OAMessageTextInputBean tableNameSearchBean = (OAMessageTextInputBean) webBean.findChildRecursive ("tableName");
  	String tableName = tableNameSearchBean.getText (pageContext);

  What I am doing wrong?  How do you get the value of an item that should be part of the shipment?

  Thank you

  Hello

  Can you please use--> tableNameSearchBean.getValue (pageContext) and check the result?

  In addition, if you can explain with an example of prior value and a new, it will be easier to help.

• Exception while trying to get the selected value for the choice of SelectOne in ADF Mobile

  I added the following code after arriving through this post https://forums.oracle.com/thread/2536419

  DCBindingContainer dcBindings = (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();

  DCIteratorBinding iterBind = (DCIteratorBinding) dcBindings.get ("facilitySelectItems");

  Attribute String = (String) iterBind.getCurrentRow () .getAttribute (0);

  But Jdeveloper complained class BindingContext wasn't available and I get the jar file adfm.jar has not been added to the project. I added it manually the path C:\JDeveloper11r24\oracle_common\modules\oracle.adf.model_11.1.1\adfm.jar. Once I've deployed code on an android emulator, I get the below error. Can someone please?

  07-25 13:18:03.812: D/CordovaLog (869): [SEVERE - oracle.adfmf.framework - adf.mf.internal - logError] request: {classname: oracle.adfmf.framework.api.Model; method: evaluateMethodExpression; params: [0: #{pageFlowScope.IBCMSearchBean.getSearchParams}] [1:] [2: {}] [3:] ;} exception: {message: oracle/adf/model/binding/DCBindingContainer (unsupported major.minor version 50.0); the severity: ERROR; .Guy: oracle.adfmf.framework.exception.AdfException; .exception: true ;}}}

  The version of the compiler maximum the JDev shows that 1.4. And I'm using version 11.1.2.4.0 for JDeveloper. The JDK version is 1.6.0_24.

  Sorry I missed the question!

  First of all, to get the value of selectedItem in selectOneChoice do not have another function in the domain controller. Here is an excellent article by Frank that explains this. Or you can use the below function to get the selected value immediately. Here the market is the value of selectOneChoice attribute. I wasn't aware of this method until you have read this article.

  {} public void getAndSetMarketValue (market of the object)

  ValueExpression ve = (ValueExpression) AdfmfJavaUtilities.getValueExpression ("#{bindings.marketSelectItems}", Object.class);

  AmxAttributeBinding attrBinding = (AmxAttributeBinding) ve.getValue (AdfmfJavaUtilities.getAdfELContext ());

  access the iterator that populates the list of values in

  the selectManyChoice component

  AmxIteratorBinding amxListIterator = attrBinding.getIteratorBinding ();

  the AmxIteratorBinding is a wrapper for the BasicIterator

  iterator which sets out the information we need

  ListIterator BasicIterator = amxListIterator.getIterator ();

  for each index value, query the name of the service (you can

  access and attribute from the line) to display

  SelectedValue = string

  (String) listIterator.getAttributeValueAtIndex (((New Integer ((String) market))) .intValue (), "Value");

  }

  Second, you can use #{row} in commandLink's action since it is something that is evaluated when the user clicks on the link and we do not have access to #{line} after that the entire component is rendered. To remedy this give an action for the commandlink which is a function in the bean and the function of bean back to the action of the link selected.

  ListOfReports.amx

  .......

  .......

  LoginBean.java

  ......

  public String returnClickValue() {}

  Option of string = AdfmfJavaUtilities.evaluateELExpression("#{viewScope.selectedItem}").toString ();

• How to get the current value of db in backing bean

  Hello
  
  I use jdeveloper 11.1.2.3.0
  
  I would like to know how I could access the old value of an attribute in backing bean.
  I know I can get it in terms of EntityImpl with the getPostedAttribute function,
  but as I see that I'm not allowed to access this function in the ViewImpl.
  I get this error:
  Error (151,33): getPostedAttribute (int) has protected access to oracle.jbo.server.EntityImpl.
  
  Could you help her?
  What is the right way to get the current value on db in backing bean?
  
  Thank you very much!

  You can add a transitional attribute to the entity object to hold the old value of the desired attribute, then you can add this attribute to the view object.

• How to check the previous value of the element in a multi-record block

  Oracle Version: 10 g
  Forms Version: 10 g
  
  Hi all
  Hello everyone, I have a multi-dossier block in a form where one of the values of elements is of LOV.user can select the value of LOV.
  
  If once the user selects the value of LOV and moves to the next of the multi-file record, and selects the value of LOV again, I shouldn't allow users to select the previous value of the user in order to avoid duplication of records.
  
  and important remark is that I should get there before you save it in the database because once registered in the database I can compare the values and hide the previous value.
  
  
  Any help will be appreciated.
  
  
  Thanks and greetings

  This is a question frequently asked in the forum! There are several different solutions. Take a look at the following articles. Both will perform the necessary verification of duplicates.
  Forms - registration of treatment group (value in double check...
  or
  Avoid records duplicated in a block

  If none of these solutions don't work for you, search the forum for other options.

  Hope this helps,

• How set the value of a LOV in CO prgramatically and get the Pkey value?

  Hello
  
  I need to get the Primaykey LOV will return and set a value for a LOV, say ItemLOV in a page through CO. How can I achieve this?
  
  Req:
  1. set the nom_element, say "DELL_1618" so that the page displays this in the LOV.
  2 get the PK value returned by LOV in the backend in an attribute of VO say Item_ID, ' 100009881'.
  
  Thank you
  Sicard.

  Hi Santosh,

  Sorry, I responded to general LOV scenario, but want to put it right,

  You need run your LOV query to the controller for the "DELL_1618" element using the prepared command, get the value of the value display and Id and assign the LOV and FormVlaue in the PR of the controller.

• Get the selected value in the list drop-down/messagechoice

  Hi friends,

  oamc.setListDisplayAttribute ("MyDescription");
  oamc.setID ("xxMypicklist");
  oamc.setRendered (Boolean.TRUE);
  oawebbean.addIndexedChild (oamc);
  
  This shows the list of choices and there MyVO1 query search results.
  
  Now, I want retrieve value MyId in the processFromRequest (after pushing a button on the screen). I do the following:
  
  OAApplicationModule am = pageContext.getApplicationModule (webBean);
  ...
  MyVOImpl myvoimpl = (MyVOImpl) am.findViewObject("MyVO1");
  MyVORowImpl PicklistRow = myvoimpl.getCurrentRow ((MyVORowImpl));
  NUMBER auxId = (NUMBER) PicklistRow.getAttribute ("MyId"); THIS SENTENCE GIVES A NULL POINTER EXCEPTION
  
  Then..., is not enough to find the original Version? and get the rank "perceive"... and then get the desired attribute?
  
  Do I need to load data from MyVO1 into myvoimpl? How? How to get the folder selected on the screen?
  
  Many thanks for any help. It is very urgent for me to solve this problem. Dev guide does not help with this kind of usual problems.

  Hello

  u can not get the value of this way, becz you try to get the value of the original Version which is used for bean of choice message, to get the value selected in this field of choicebean message, you must get the VO initialized for this page, both would be different VO, you can opt for the following approach

  (1.) an another VO wiil be there in your page get implemented to capture the data on this page, the attribute of this VO would be added to your field of beans of choice, need to understand that VO and and capture your selected value.

  or the other way is

  2.), you can change your code in the same way in the pR method

  OAMessageChoiceBean OAMC = oapagecontext.getWebBeanFactory () .createWebBean (oapagecontext, OAWebBeanConstants.MESSAGE_CHOICE_BEAN, null, "XXMypicklistBean) (OAMessageChoiceBean);

  and get the selected value in pFR method in this way

  OAMessageChoiceBean getCHBean = (OAMessageChoiceBean) (webBean.findIndexedChildRecursive ("XXMypicklistBean"));

  String val = (String) getCHBean.getValue (pageContext));
