HI,
I have used below code for getting details from databse. Now i have to insert a row in the database.
Kindly let me know how can i use below code for inserting a row in the database. or should i make any change in its viewObject's Query.
If there is any another way of inserting data in database through method binding please let me knoe that.
ApplicationModule myService = ADFUtils.getApplicationModuleForDataControl("AppModuleDataControl");
ViewObject userInfoVO = myService.findViewObject("EmployeeViewParam1");
userInfoVO.executeQuery();
DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding dcItteratorBindings =
bindings.findIteratorBinding("EmployeeViewParam1Iterator");
RowSetIterator rowIter1 = dcItteratorBindings.getRowSetIterator();
Row[] rows1 = rowIter1.getAllRowsInRange();
for(int i=0;i<rows1.length;i++)
this.empId = (String)rows1.getAttribute("EmployeeId"); // primary key
this.employeeName = (String)rows1[i].getAttribute("Employeename");
