jsp中調用oracle存儲過程的實例

       前段時間上傳瞭如何在jsp、java中調用oracle存儲過程的例子，如今把其中有用的部分摘錄出來以作參考。錯誤之處望見諒！

      上傳見：http://down.51cto.com/data/219597  

--存儲過程：
--包：
create or replace package pck_recond
as

------------------------------聲明遊標變量
  type t_recond_cursor is ref cursor return icdmain.t_pub_commoninfo%rowtype; --弱遊標類型
  type y_recond_cursor is ref cursor; --強遊標類型

-----------------------------返回錄音的存儲過程
  procedure   p_getrecond(i_serialno     in  icdmain.t_pub_commoninfo.serialno%type,
                          i_callerno     in  icdmain.t_pub_commoninfo.callerno%type,
                          i_accepterno   in  icdmain.t_pub_commoninfo.accepterno%type,
                          i_checkflag    in  icdmain.t_pub_commoninfo.checkflag%type,
                          o_dataset      out  y_recond_cursor --返回數據集
                          );

----------------------------更新質檢狀態的存儲過程

procedure p_updaterecond(i_serialno  in  icdmain.t_pub_commoninfo.serialno%type,
                         i_remark    in  icdmain.t_pub_commoninfo.remark%type
                         );

---------------------------存儲過程分頁
PROCEDURE p_query
       (i_tableName        in  varchar2,   --表名
        i_curPage          in out Number,  --當前頁 in out
        i_pageSize         in out Number,  --每頁顯示記錄條數  in out
        i_totalRecords     out Number,     --總記錄數
        i_totalPages       out Number,     --總頁數
        o_cur              out y_recond_cursor --返回數據集
        );

 ------------------------登錄
PROCEDURE p_login
       (i_staffno       in   icdmain.t_pub_staff.staffno%type,   --用戶no
        i_password      in   icdmain.t_pub_staff.password%type,    --密碼
        o_staffno       out  icdmain.t_pub_staff.staffno%type,
        o_msg           out  varchar2, ----返回錯誤消息
        o_login         out  number,
        o_staffstatus   out  number
        );  
                  
----------------------退出
PROCEDURE P_LOGOUT
       (i_staffno       in   icdmain.t_pub_staff.staffno%type  --用戶no
        );  
                  
end pck_recond;

       i_curPage := 1;

   IF i_curPage > i_totalPages THEN
       i_curPage := ceil(i_totalPages);

  --實現分頁查詢
   v_startRecord := (i_curPage - 1) * i_pageSize + 1;
