public String changeUserName(int workid) throws SQLException
  {        
    
    WorkIdDao wdao = new WorkIdDao();
    ArrayList list = wdao.workId_select(workid);
    
    if(list.isEmpty())  
    {  
      return "<font color=red face=Script MT Bold><b>该用户不存在</b></font>";      
    }
    
    else{      
      
      return "<font color=green face=Script MT Bold><b>通过验证</b></font>";
    }
    
  }
