通用存储过程分页
create procedure select_pagesize( @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)--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
