如何分割值並更新查詢

Question

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"; 





    } 

now stmt.setString（3，claimDetailsBean.getDucode（））;來自動作方法值＃1的值我需要拆分這個（值＃1）並且只更新查詢值。我不想要＃1 如何拆分和更新請任何一個幫助？

Answer 1

，你可以簡單地使用分割功能的Java

public String[] split(String regex, int limit) 

或

public String[] split(String regex) 

Answer 2

您可以使用子

claimDetailsBean.getDucode().substring(0, claimDetailsBean.getDucode().indexOf("#")) 

你可以拿出claimDetailsBean.getDucode（）在單獨的變量並且在DuCode可以爲null的情況下肯定檢查爲空。
