一个不错的分页存储过程
支持多表联合，时间（多条记录相同）排序，但唯一不太好的就是占用资源的点大，希望有空的时候好好改改
CREATE procedure p_show2
(
@select_list varchar(1000)=\'*\',--不需要select
@table_name varchar(100),
@where varchar(1000)=\'\',--不需要where
@primary_key varchar(100),--当是表联合时，加表名前缀.
@order_by varchar(200),--需要完整的子句 order by ...
@page_size smallint=20,--每页记录
@page_index int=1,--页索引
@do_count bit=0,
@iPageCount int = 1 OUTPUT, --总的记录数
@pageCount int = 1 output ----查询结果分页后的总页数
)--1只统计总数

/*
过程名：通用存储过程分页
使用示例:
单表sql调用：exec select_pagesize \'login_id,login_name\',\'tb_login\',\' login_name like \'\'%%\'\'\',\'login_id\',\' order by login_dt desc\',20,10
多表sql调用：exec select_pagesize \'a.login_id,a.login_name,b.pro_name\',\'tb_login a,tb_code_province b\',\' a.pro_id=b.pro_id and a.login_name like \'\'%%\'\'\',\'a.login_id\',\' order by a.login_dt desc\',20,10
备注：外部程序调用不需要转义单引号
原型结构：select top 20 select_list
from tablename
where z_id not in(select z_id from (select top 100 z_id from tablename order by order_by) temptable)
and ...
order by order_by
