vo.setWhereClauseParam(0,"2");
vo.executeQuery();but i have an error "Missing IN or OUT parameter at index:: 1"

Answer 1

i did an expert mode view like this:
select empno
, ename
from emp
where exists
select 'x'
from emp_reports
where report_year=?)
and used it in a data forward action like this:
public void onSetCurrentRowWithKey( DataActionContext ctx )
     System.out.println("onSetCurrentRowWithKey-Start");
     // do this event
     invokeEventAction( ctx );
    DCBindingContainer bc = ctx.getBindingContainer();
    DCIteratorBinding iter = bc.findIteratorBinding("ViewEmpReportsDueView1Iterator");
    Row parent = iter.getCurrentRow();
    ViewEmpReportsDueViewRow empRptDueRow = (ViewEmpReportsDueViewRow) parent;
     String strReportYear = empRptDueRow.getReportYear();
     AppModule am = (AppModule) getApplicationModule("AppModuleDataControl", ctx );
     ViewObject vo = am.findViewObject("EmpReportLookupExpertView1");
     vo.setWhereClauseParam(0, strReportYear );
     vo.executeQuery();
     Row r = vo.first();
     if (r!=null) {
        System.out.println( r.getAttribute("Empno") );
     System.out.println("onSetCurrentRowWithKey-End");
and it worked ok - no errors.
