Pass values to bind variales and execute VO query

Question

Hi All,
I have a requirement to add validation to an appraisal page via OAF.
As a part of testing I need to check, if the values in the query of VO is displayed in the page.
VO - QuestAnsValuesVO
EO - QuestAnswerValueEO, QuestFieldEO
The VO query is
SELECT * FROM (SELECT QuestAnswerValueEO.QUEST_ANSWER_VAL_ID, QuestAnswerValueEO.QUESTIONNAIRE_ANSWER_ID, QuestAnswerValueEO.FIELD_ID, QuestAnswerValueEO.OBJECT_VERSION_NUMBER, QuestAnswerValueEO.VALUE, QuestFieldEO.FIELD_ID AS QUEST_FIELD_ID, QuestFieldEO.NAME, QuestFieldEO.TYPE, QuestFieldEO.HTML_TEXT, rank() over (partition by QuestFieldEO.NAME order by QuestFieldEO.FIELD_ID) AS RANK, QuestAnswerValueEO.QUESTIONNAIRE_ANSWER_ID AS QUESTIONNAIRE_ANSWER_ID1 FROM HR_QUEST_ANSWER_VALUES QuestAnswerValueEO, HR_QUEST_FIELDS QuestFieldEO WHERE QuestFieldEO.QUESTIONNAIRE_TEMPLATE_ID(+) = :1 and QuestAnswerValueEO.QUESTIONNAIRE_ANSWER_ID(+) = :2 AND QuestFieldEO.FIELD_ID = QuestAnswerValueEO.FIELD_ID (+)) QRSLT ORDER BY QUEST_FIELD_ID
I am trying to execute this query in the extended controller class so that i can get the values printed on the page. I am getting SQL exception saying - not all variables are bound.
How do i pass values to bind variables :1 and :2 and execute this query?
Please help.
Thanks

Geetha,
Instead of :1 and :2 use a named bind variable as part of your VO and then set either a default value or set its value during runtime. See this example on how to create bind variable:
http://formattc.wordpress.com/2010/04/02/custom-java-bind-variable-in-a-where-clause-of-an-adf-view-object/
Once created, you can set its value during runtime either in ApplicationModuleImpl or in ViewObjectImpl class
e.g.,
         ViewObjectImpl view = this.getEmpView();
        VariableValueManager vm = view.ensureVariableManager();
        vm.setVariableValue("empNo", value);
        view.executeQuery();regards,
