通过实例学习sql server数据库是如何分页查询数据的。
首先，建立表：
复制代码 代码示例:
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)
复制代码 代码示例:
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
以下是三种分页查询的方案，大家对比下，这里推荐第一种sql分页代码。
分页方案1：(利用not in和select top分页)
语句形式：
复制代码 代码示例:
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2：(利用id大于多少和select top分页）
语句形式：
复制代码 代码示例:
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3：(利用sql的游标存储过程分页)
复制代码 代码示例:
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
exec sp_cursorclose @p1
set nocount off
