for inserting and viewing the record with persion fields u must obey
the following steps
1-create a table like this
create table persion(id int,name nvarchar2(30));
(Data type must be NvarChar2)
2-for inserting records ,the insert command must be like this
insert into persion(1,N'Farsi');
(do forget "N" and do this in a jsp or servlet or app,not in SQLplus)
3-if u want see the records,the header of jsp is:
<%@ page contentType="text/html;charset=UTF-8" import="java.sql.*"%>
<HTML>
<HEAD>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=UTF-8">
</Head>
notice that u cannot see the farsi records in SQLPlus,but in
EnterPrice Manager u can.and regardless Werbserver u can do it,even in
Linux.
