Query on EO Object

Question

Hello Gurus..
I have a requirement. I have a EO - "InsertDeviceDetailsEO"; VO - "InsertDeviceDetailsEOView" and AM - "DeviceDetailsAM"
I have a Page DeviceDetails with a button "CreateDevice". When user clicks on this button a new page is open for entering devicedetails.
In this page I am not showing a database field DEVICEID but i want that when user enters other details ans click on "Apply" button this id will be automatically generated and stored in the database table with all user entered field.
How to achieve this ?
Regards
Ajay Sharma

Hi Naren,
Here is my code..
Still it giving me standard error not user defined error.
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
OAApplicationModule am = pageContext.getApplicationModule(webBean) ;
if(pageContext.getParameter("Apply")!=null){
String deviceCode = pageContext.getParameter("DeviceCode1");
OADBTransaction transaction = am.getOADBTransaction();
String query = "select Device_Code from XXIOS_DEVICE_DETAILS " +
"where Device_code = "+deviceCode;
ResultSet resultSet;
int resultCount = 0;
PreparedStatement preparedStatement = transaction.createPreparedStatement(query,0);
System.out.println("Prepared Staement Created = "+ preparedStatement);
try{
resultSet= preparedStatement.executeQuery();
System.out.println("Result Set Created = "+ resultSet);
while(resultSet.next()){
if(resultSet.getString("Device_Code").equalsIgnoreCase(deviceCode));
throw new OAException ("Device Code is Already Present. Please Provide Unique Device Code");
}// end while
}// end try
catch(Exception e){
throw new OAException (e.getMessage(),OAException.ERROR);
}// end catch
}// end main if
//am.invokeMethod("validateData");
am.invokeMethod("insertDataToDeviceDetailsTable") ;
