本節的數據編輯插教程給我們簡單介紹如何提高MySQL數據分頁效率，下面我們將會給出的這段代碼是大數據量時提高分頁的效率的測試代碼。
如果你也需要設置MySQL數據提高分頁效率，那麼，就一起來看看代碼段吧!
--提高分頁效率:實現分頁時只讀取顯示數據,需要先在數據庫創建數據庫“TestForPaging”
use TestForPaging
go
--創建表SomeData
create table SomeData
(
id int primary key,
name varchar(30) null,
description text
)
go
--插入數據
insert into SomeData values(1,'num1','第1條')
go
insert into SomeData values(2,'num2','第2條')
go
insert into SomeData values(3,'num3','第3條')
go
insert into SomeData values(4,'num4','第4條')
go
insert into SomeData values(5,'num5','第5條')
go
--數據條目總數
select count(*) from SomeData
go
--給每條記錄添加一個數據級別
select name,description,ROW_NUMBER() over(order by id desc)as dataLevel from SomeData
go
--查看指定的數據級別間的數據條目
select dataLevel,name,description from
(select name,description,row_number() over(order by id desc)as dataLevel from SomeData)
as datawithleverl where dataLevel between 2 and 4
go
--實現查看指定的數據級別間的數據條目的存儲過程
create procedure GetDataPaged
(
@startRowIndex int,
@maximumRows int,
@sort varchar
)
AS
--確保指定sort
if len(@sort)=0
set @sort='id'
--帶參數的查詢
select dataLevel,name,description from
(select name,description,row_number() over(order by @sort desc)as dataLevel from SomeData) AS datawithleverl
WHERE dataLevel > (@startRowIndex*10) AND dataLevel <= (@startRowIndex*10 + @maximumRows)
go
