OracleConnection connect = new OracleConnection();
Connection conn = connect.oracleConn();
Statement statement = conn.createStatement();
String sql = "insert into testinsert (ssn) values ('مرحبا') ";
statement.executeQuery(sql);
System.out.println("success");
数据从数据库显示为????在实现上面的java代码之后
但是当从sqlplus 10g本身插入数据时
insert into testinsert (ssn) values ('مرحبا')
数据显示从数据库中显示为مرحبا
