sql分頁儲存過程
create procedure [dbo].[up_pagerdata]
(@tables varchar(400),
@primarykey varchar(100),--當是表聯合時，加表名字首.
@sort varchar(200),--需要完整的子句 order by ...
@currentpage int=1,--頁索引
@pagesize smallint=20,--每頁記錄
@fields varchar(1000)='*',--不需要select
@filter varchar(1000)='',--不需要where
@docount bit=0,--1只統計總數
@linecount varchar(20)='0' output)as
/*過程名：通用儲存過程分頁
使用示例:
單錶sql呼叫：exec sp_pagination_test 'tb_login','login_id','order by login_dt desc','1','50','*','login_ist=0 and long_3=0','0'
多表sql呼叫：exec sp_pagination_test 'tb_login a,tb_code_province b','a.login_id',' order by a.login_dt desc',1,20,'*',' a.pro_id=b.pro_id and a.login_name like ''%%''','a.login_id,a.login_name,b.pro_name','a.login_id',0
備註：外部程式呼叫不需要轉義單引號
原型結構：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
