根据SalesOrderID排序，取第16-18行这3条记录。
方法一：(最常用的分页代码， top / not in)
SELECT TOP 3 [SalesOrderID], [RevisionNumber], [OrderDate]
FROM [AdventureWorks2012].[Sales].[SalesOrderHeader]
WHERE [SalesOrderID] NOT IN ( SELECT TOP 15 [SalesOrderID]
FROM [AdventureWorks2012].[Sales].[SalesOrderHeader]
ORDER BY [SalesOrderID] )
ORDER BY SalesOrderID;
备注： 注意前后的order by 一致
方法二：排名开窗函数 (row_number() over (order by ))
SELECT [SalesOrderID], [RevisionNumber], [OrderDate]
FROM ( SELECT [SalesOrderID], [RevisionNumber], [OrderDate] ,
ROW_NUMBER() OVER ( ORDER BY SalesOrderID ) AS rowid
FROM [AdventureWorks2012].[Sales].[SalesOrderHeader] ) cte
WHERE rowid
BETWEEN 16 AND 18;
方法三：(offset /fetch next, SQL Server 2012支持，性能最好！)
SELECT [SalesOrderID], [RevisionNumber], [OrderDate] FROM [AdventureWorks2012].[Sales].[SalesOrderHeader] ORDER BY SalesOrderID OFFSET 15 ROW FETCH NEXT 3 ROWS ONLY;
总结：利用变量进行分页
DECLARE @page INT, @size INT, @Total INT;
SELECT @page = 3, @size = 10; --当前页面为3，页面大小为10
-------方法一
SELECT TOP ( @size ) [SalesOrderID], [RevisionNumber], [OrderDate]
FROM [AdventureWorks2012].[Sales].[SalesOrderHeader]
WHERE [SalesOrderID] NOT IN ( SELECT TOP (( @page - 1 ) * @size ) [SalesOrderID]
FROM [AdventureWorks2012].[Sales].[SalesOrderHeader]
ORDER BY [SalesOrderID] )
ORDER BY SalesOrderID;
-------方法二
SELECT [SalesOrderID], [RevisionNumber], [OrderDate]
FROM ( SELECT [SalesOrderID], [RevisionNumber], [OrderDate] ,
ROW_NUMBER() OVER ( ORDER BY SalesOrderID ) AS rowid
FROM [AdventureWorks2012].[Sales].[SalesOrderHeader] ) cte
WHERE rowid
BETWEEN ( @page - 1 ) * @size + 1 AND @page * @size;
-------方法三
SELECT [SalesOrderID], [RevisionNumber], [OrderDate]
FROM [AdventureWorks2012].[Sales].[SalesOrderHeader]
ORDER BY SalesOrderID OFFSET ( @page - 1 ) * @size ROWS FETCH NEXT @size ROWS ONLY; ---offset的当前页面是从零开
