SQL基础:SQL Server实现分页方法介绍
一、创建测试表
CREATE TABLE [dbo].[Student](
[id] [int] NOT NULL,
[name] [nvarchar](50) NULL,
[age] [int] NULL)
[id] [int] NOT NULL,
[name] [nvarchar](50) NULL,
[age] [int] NULL)
二、创建测试数据
declare @i int
set @i=1
while(@i<10000)
begin
insert into Student select @i,left(newid(),7),@i+12
set @i += 1
end
set @i=1
while(@i<10000)
begin
insert into Student select @i,left(newid(),7),@i+12
set @i += 1
end
三、测试
1、使用top关键字
top关键字表示跳过多少条取多少条
declare @pageCount int –每页条数
declare @pageNo int –页码
declare @startIndex int –跳过的条数
set @pageCount=10
set @pageNo=3
set @startIndex=(@pageCount*(@pageNo-1))
select top(@pageCount) * from Student
where ID not in
(
select top (@startIndex) ID from Student order by id
) order by ID
declare @pageNo int –页码
declare @startIndex int –跳过的条数
set @pageCount=10
set @pageNo=3
set @startIndex=(@pageCount*(@pageNo-1))
select top(@pageCount) * from Student
where ID not in
(
select top (@startIndex) ID from Student order by id
) order by ID
测试结果:
2、使用row_number()函数
declare @pageCount int –页数
declare @pageNo int –页码
set @pageCount=10
set @pageNo=3
–写法1:使用between and
select t.row,* from
(
select ROW_NUMBER() over(order by ID asc) as row,* from Student
) t where t.row between (@pageNo-1)*@pageCount+1 and @pageCount*@pageNo
–写法2:使用 “>”运算符
select top (@pageCount) * from
(
select ROW_NUMBER() over(order by ID asc) as row,* from Student
) t where t.row >(@pageNo-1)*@pageCount
–写法3:使用and运算符
select top (@pageCount) * from
(
select ROW_NUMBER() over(order by ID asc) as row,* from Student
) t where t.row >(@pageNo-1)*@pageCount and t.row<(@pageNo)*@pageCount+1
declare @pageNo int –页码
set @pageCount=10
set @pageNo=3
–写法1:使用between and
select t.row,* from
(
select ROW_NUMBER() over(order by ID asc) as row,* from Student
) t where t.row between (@pageNo-1)*@pageCount+1 and @pageCount*@pageNo
–写法2:使用 “>”运算符
select top (@pageCount) * from
(
select ROW_NUMBER() over(order by ID asc) as row,* from Student
) t where t.row >(@pageNo-1)*@pageCount
–写法3:使用and运算符
select top (@pageCount) * from
(
select ROW_NUMBER() over(order by ID asc) as row,* from Student
) t where t.row >(@pageNo-1)*@pageCount and t.row<(@pageNo)*@pageCount+1
四、总结
ROW_NUMBER()只支持sql2005及以上版本,top有更好的可移植性,能同时适用于sql2000及以上版本、access。
