hibernate如何执行SQL的insert操作（不是HQL哦，是SQL语句）

public int insertValue(int pid,String vcode,String vvalue,String state,String mname){        int flag = 0;        Session session = null;        Transaction tr = null;        try{            if(pid>0&&vcode!=null&&vvalue!=null&&mname!=null){                session = getSession();                String sql = "insert into sf_3_clinic(pid,"+vcode+") values("+pid+","+vvalue+")";                 System.out.println(sql);                tr=session.beginTransaction();                //Statement state1 = session.connection().createStatement();                session.createSQLQuery(sql);                tr.commit();                 session.close();            }        }catch(Exception e){            e.printStackTrace();return 0;        }        return 0;    }
