sql server 存储过程的分页
建立表：
create table [testtable] (
[id] [int] identity (1, 1) not null ,
[firstname] [nvarchar] (100) collate chinese_prc_ci_as null ,
[lastname] [nvarchar] (100) collate chinese_prc_ci_as null ,
[country] [nvarchar] (50) collate chinese_prc_ci_as null ,
[note] [nvarchar] (2000) collate chinese_prc_ci_as null
) on [primary]
go
插入数据：(2万条，用更多的数据测试会明显一些)
set identity_insert testtable on
declare @i int
set @i=1
while @i<=20000
begin
insert into testtable([id], firstname, lastname, country,note) values(@i, ’’firstname_xxx’’,’’lastname_xxx’’,’’country_xxx’’,’’note_xxx’’)
set @i=@i+1
end
set identity_insert testtable off

分页方案一：(利用not in和select top分页)
语句形式：
select top 10 *
from testtable
where (id not in
(select top 20 id
from testtable
order by id))
order by id
select top 页大小 *
from testtable
where (id not in
(select top 页大小*页数 id
from 表
order by id))
order by id
-------------------------------------
分页方案二：(利用id大于多少和select top分页）
语句形式：
select top 10 *
from testtable
where (id >
(select max(id)
from (select top 20 id
from testtable
order by id) as t))
order by id
select top 页大小 *
from testtable
where (id >
(select max(id)
from (select top 页大小*页数 id
from 表
order by id) as t))
order by id
-------------------------------------
分页方案三：(利用sql的游标存储过程分页)
create procedure xiaozhengge
@sqlstr nvarchar(4000), --查询字符串
@currentpage int, --第n页
@pagesize int --每页行数
as
set nocount on
declare @p1 int, --p1是游标的id
@rowcount int
exec sp_cursoropen @p1 output,@sqlstr,@scrollopt=1,@ccopt=1,@rowcount=@rowcount output
select ceiling(1.0*@rowcount/@pagesize) as 总页数--,@rowcount as 总行数,@currentpage as 当前页
set @currentpage=(@currentpage-1)*@pagesize+1
exec sp_cursorfetch @p1,16,@currentpage,@pagesize
