Oracle 创建分页存储过程（转帖）

ps：源代码还有很多错误，我修改了

---------------------------------------------这是分割线-------------------------------------------------------

以下为创建包

create or replace package p_page is
-- Author : PHARAOHS
-- Created : 2006-4-30 14:14:14
-- Purpose : 分页过程
TYPE type_cur IS REF CURSOR;--定义游标变量用于返回记录集
PROCEDURE Pagination(
Pindex in number, ---分页索引
Psql in varchar2, --产生dataset的sql语句
Psize in number, --页面大小
Pcount out number, --返回分页总数
v_cur out type_cur ); --返回当前页数据记录

procedure PageRecordsCount(
Psqlcount in varchar2, --产生dataset的sql语句
Prcount out number); ---返回记录总数
end p_page;

---------------------------------------------这是分割线-------------------------------------------------------

以下创建包体

create or replace package body p_page is
PROCEDURE Pagination (
Pindex in number,
Psql in varchar2,
Psize in number,
Pcount out number,
v_cur out type_cur)

AS
v_sql VARCHAR2(1000);
v_count number;
v_Plow number;
v_Phei number;
Begin
------------------------------------------------------------取分页总数
v_sql := 'select count (*) from (' || Psql || ')';
execute immediate v_sql into v_count;
Pcount := ceil (v_count/Psize);
------------------------------------------------------------显示任意页内容
v_Phei := Pindex * Psize + Psize;
v_Plow := v_Phei - Psize + 1;
--Psql := 'select rownum rn,t.* from zzda t' ; --rownum
v_sql := 'select * from (' || Psql || '( where rn between ' || v_Plow || ' and ' || v_Phei ;
open v_cur for v_sql;
End Pagination;
