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)?

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 @PageSize INT = 200
DECLARE @SortByField int = 1 --The field used for sort by
DECLARE @SortOrder nvarchar(255) = 'ASC' --ASC or DESC
DECLARE @FilterType nvarchar(255) = 'None' --The filter type, as defined on the client side (None/Contain/NotContain/Match/NotMatch/True/False/)
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.

WHERE
( -- We apply the filter logic here
CASE

-- Name column filter

对于ROW_NUMBER技术，如果你没有一个排序列，你可以使用CURRENT_TIMESTAMP，如下所示:
SELECT TOP 20
col1,
col2,
col3,
col4
FROM (
SELECT
tbl.col1 AS col1
,tbl.col2 AS col2
,tbl.col3 AS col3
,tbl.col4 AS col4
,ROW_NUMBER() OVER (
ORDER BY CURRENT_TIMESTAMP
) AS sort_row
FROM dbo.MyTable tbl
) AS query
WHERE query.sort_row > 10
ORDER BY query.sort_row
对于我来说，这种方法在搜索表大小甚至高达700,000的情况下效果很好。
这将获取记录11到30。
从2012年起，我们可以使用 偏移10行只获取下10行
MSDN: ROW_NUMBER (Transact-SQL)
返回结果集中分区内某一行的顺序编号，每个分区中的第一行从1开始。 下面的示例按照OrderDate的顺序返回数字为50到60的行。
WITH OrderedOrders AS
(
SELECT
ROW_NUMBER() OVER(ORDER BY FirstName DESC) AS RowNumber,
FirstName, LastName, ROUND(SalesYTD,2,1) AS "Sales YTD"
FROM [dbo].[vSalesPerson]
)
SELECT RowNumber,
FirstName, LastName, Sales YTD
FROM OrderedOrders
WHERE RowNumber > 50 AND RowNumber < 60;
RowNumber FirstName LastName SalesYTD
