SQL Server分頁方法匯總
根據SalesOrderID排序,取第16-18行這3條記錄。
方法一:(最常用的分頁代碼, 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;
備註: 註意前後的order by 一致
方法二:排名開窗函數 (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;
總結:利用變量進行分頁
DECLARE @page INT, @size INT, @Total INT; SELECT @page = 3, @size = 10; --當前頁面為3,頁面大小為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的當前頁面是從零開
