在SQL Server 2000、2005、2008、2012中分页结果的最佳方法(性能方面)是什么?如果你还想获得结果的总数(在分页之前)?
当前回答
好吧，我已经在我的SQL 2000数据库中使用了以下示例查询，它也适用于SQL 2005。它通过使用多个列来动态排序。 我告诉你……这是强大的:)
ALTER PROCEDURE [dbo].[RE_ListingReports_SelectSummary]
@CompanyID int,
@pageNumber int,
@pageSize int,
@sort varchar(200)
AS
DECLARE @sql nvarchar(4000)
DECLARE @strPageSize nvarchar(20)
DECLARE @strSkippedRows nvarchar(20)
DECLARE @strFields nvarchar(4000)
DECLARE @strFilter nvarchar(4000)
DECLARE @sortBy nvarchar(4000)
DECLARE @strFrom nvarchar(4000)
DECLARE @strID nvarchar(100)
If(@pageNumber < 0)
SET @pageNumber = 1
SET @strPageSize = CAST(@pageSize AS varchar(20))
SET @strSkippedRows = CAST(((@pageNumber - 1) * @pageSize) AS varchar(20))-- For example if pageNumber is 5 pageSize is 10, then SkippedRows = 40.
SET @strID = 'ListingDbID'
SET @strFields = 'ListingDbID,
ListingID,
[ExtraRoom]
'
SET @strFrom = ' vwListingSummary '
SET @strFilter = ' WHERE
CompanyID = ' + CAST(@CompanyID As varchar(20))
End
SET @sortBy = ''
if(len(ltrim(rtrim(@sort))) > 0)
SET @sortBy = ' Order By ' + @sort
-- Total Rows Count
SET @sql = 'SELECT Count(' + @strID + ') FROM ' + @strFROM + @strFilter
EXEC sp_executesql @sql
--// This technique is used in a Single Table pagination
SET @sql = 'SELECT ' + @strFields + ' FROM ' + @strFROM +
' WHERE ' + @strID + ' IN ' +
' (SELECT TOP ' + @strPageSize + ' ' + @strID + ' FROM ' + @strFROM + @strFilter +
' AND ' + @strID + ' NOT IN ' + '
(SELECT TOP ' + @strSkippedRows + ' ' + @strID + ' FROM ' + @strFROM + @strFilter + @SortBy + ') '
+ @SortBy + ') ' + @SortBy
Print @sql
EXEC sp_executesql @sql
最好的部分是sp_executesql缓存以后的调用，只要您传递相同的参数，即生成相同的sql文本。

这是2012年老SO问题的重复: 实现分页的有效方法
从[TableX] ORDER BY [FieldX] 偏移量500行 只获取下100行
这里将更详细地讨论这个主题，并使用替代方法。
这些是我在SQL server端对查询结果进行分页的解决方案。 这些方法在SQL Server 2008和2012之间是不同的。 此外，我还添加了过滤和排序的概念。当你在Gridview中分页、过滤和排序时，它是非常高效的。
在测试之前，你必须创建一个示例表，并在这个表中插入一些行:(在现实世界中，你必须改变Where子句，考虑到你的表字段，也许你有一些连接和子查询在select的主要部分)
Create Table VLT
(
ID int IDentity(1,1),
Name nvarchar(50),
Tel Varchar(20)
)
GO
Insert INTO VLT
VALUES
('NAME' + Convert(varchar(10),@@identity),'FAMIL' + Convert(varchar(10),@@identity))
GO 500000
在所有这些示例中，我想查询每页200行，我正在获取页码为1200的行。
在SQL server 2008中，您可以使用CTE概念。因此，我为SQL server 2008+编写了两种类型的查询
SQL Server 2008+
DECLARE @PageNumber Int = 1200

DECLARE @FilterValue nvarchar(255) = '' --The value the user gave for the filter
DECLARE @FilterColumn int = 1 --The column to wich the filter is applied, represents the column number like when we send the information.

您没有指定使用的语言或驱动程序。因此我只是抽象地描述它。
创建可滚动的结果集/数据集。这要求在表上有一个(多个)主表 跳到最后 请求行数 跳转到页面的开头 滚动行直到页面的末尾
获取结果总数和分页是两个不同的操作。对于这个示例，让我们假设您正在处理的查询是
SELECT * FROM Orders WHERE OrderDate >= '1980-01-01' ORDER BY OrderDate
在这种情况下，您将使用以下命令确定结果的总数:
SELECT COUNT(*) FROM Orders WHERE OrderDate >= '1980-01-01'
.．.这可能看起来效率很低，但实际上性能很好，假设所有索引等都正确设置。
接下来，要以分页方式返回实际结果，下面的查询将是最有效的:
SELECT *
FROM ( SELECT ROW_NUMBER() OVER ( ORDER BY OrderDate ) AS RowNum, *
FROM Orders
WHERE OrderDate >= '1980-01-01'
) AS RowConstrainedResult
WHERE RowNum >= 1
AND RowNum < 20
ORDER BY RowNum
这将返回原始查询的第1-19行。这里很酷的事情是，尤其是对于web应用程序，你不需要保留任何状态，除了要返回的行号。
用例方面，以下内容似乎易于使用和快速。只需设置页码。
use AdventureWorks
DECLARE @RowsPerPage INT = 10, @PageNumber INT = 6;
with result as(
SELECT SalesOrderDetailID, SalesOrderID, ProductID,
ROW_NUMBER() OVER (ORDER BY SalesOrderDetailID) AS RowNum
FROM Sales.SalesOrderDetail
where 1=1
)
select SalesOrderDetailID, SalesOrderID, ProductID from result
WHERE result.RowNum BETWEEN ((@PageNumber-1)*@RowsPerPage)+1
AND @RowsPerPage*(@PageNumber)
同样没有CTE
use AdventureWorks
DECLARE @RowsPerPage INT = 10, @PageNumber INT = 6
SELECT SalesOrderDetailID, SalesOrderID, ProductID
FROM (
SELECT SalesOrderDetailID, SalesOrderID, ProductID,
ROW_NUMBER() OVER (ORDER BY SalesOrderDetailID) AS RowNum
FROM Sales.SalesOrderDetail
where 1=1
) AS SOD
WHERE SOD.RowNum BETWEEN ((@PageNumber-1)*@RowsPerPage)+1
AND @RowsPerPage*(@PageNumber)
