public static String DuStatusinactiveanddeactive(EmpBean empBeanObj,
                                                ClaimDetailsBean claimDetailsBean,
                                                 HttpServletRequest request) throws SQLException {
        // To get Employee Details from cdm master

        String query = "update GEMS_DELIVERY_UNIT  set isActive=? , TRANS_USER=? where DU_ID=?";
        Connection conn = null;
        conn = DAO.getMsSqlConnection();
        PreparedStatement stmt = null;
        //System.out.println("came into upgradeClaim"+beanObj.getAppr1Id()+"-->"+beanObj.getAppr2Id()+"-->"+beanObj.getAwaitingAppr()+"-->"+beanObj.getClaimStatus()+"-->"+beanObj.getClaimId());
        try{
             stmt = (PreparedStatement) conn.prepareStatement(query);
             stmt.setString(1,claimDetailsBean.getDustatus());
             System.out.println("ss"+claimDetailsBean.getDustatus());
             stmt.setString(2,empBeanObj.getEmpId());
              System.out.println("emp"+empBeanObj.getEmpId());

             stmt.setString(3,claimDetailsBean.getDucode());
               System.out.println("ducode"+claimDetailsBean.getDucode());

//where du_id=arr[0];

            System.out.println(query);
            stmt.executeUpdate();
        }catch(Exception e){
            e.printStackTrace();
            return "fail";
        }
        return "Success";

    }

现在stmt.setstring（3，claimdetailsbean.getducode（））；从动作方法值#1得到值我需要拆分此值（值#1）并只更新查询值。我不想#1如何分割和更新请任何人帮助？？？
