【问题讨论】：
没有 MSSQL 2008 这样的东西。你的意思是“SQL Server 2008” 【参考方案1】：你可以使用ROW_NUMBER():
返回结果集分区内行的序号，每个分区的第一行从 1 开始。
例子：
WITH CTEResults AS
(
SELECT IDColumn, SomeField, DateField, ROW_NUMBER() OVER (ORDER BY DateField) AS RowNum
FROM MyTable
)
SELECT *
FROM CTEResults
WHERE RowNum BETWEEN 10 AND 20;
【讨论】：
【参考方案2】：你可以试试
DECLARE @Table TABLE(
Val VARCHAR(50)
)
DECLARE @PageSize INT,
@Page INT
SELECT @PageSize = 10,
@Page = 2
;WITH PageNumbers AS(
SELECT Val,
ROW_NUMBER() OVER(ORDER BY Val) ID
FROM @Table
)
SELECT *
FROM PageNumbers
WHERE ID BETWEEN ((@Page - 1) * @PageSize + 1)
AND (@Page * @PageSize)
【讨论】：
我认为这段代码不起作用。你测试过这段代码吗？ （它应该用“@Table”替换“PageNumbers”表。 @zeitgeist，它正在使用一个名为 PageNumbers 的 CTE。您是否按原样测试了代码？ 这个分页算法是错误的。对于第 1 页和第 2 页，它可以工作，但从第 3 页开始，它将开始跳过条目。第2页将从11转到20，但第3页将从22转到30跳过条目21。【参考方案3】：
SQL Server 2012 提供分页功能（请参阅http://www.codeproject.com/Articles/442503/New-features-for-database-developers-in-SQL-Server）
在SQL2008中你可以这样做：
declare @rowsPerPage as bigint;
declare @pageNum as bigint;
set @rowsPerPage=25;
set @pageNum=10;
With SQLPaging As (
Select Top(@rowsPerPage * @pageNum) ROW_NUMBER() OVER (ORDER BY ID asc)
as resultNum, *
FROM Employee )
select * from SQLPaging with (nolock) where resultNum > ((@pageNum - 1) * @rowsPerPage)
久经考验！它始终如一地工作和扩展。
【讨论】：
如果去掉顶部，结果可能会有所不同。如果您删除顶部，此方法不保证性能相同的结果，除非表已按 id 排序。【参考方案4】：1) 创建虚拟数据
CREATE TABLE #employee (EMPID INT IDENTITY, NAME VARCHAR(20))
DECLARE @id INT = 1
WHILE @id < 200
BEGIN
INSERT INTO #employee ( NAME ) VALUES ('employee_' + CAST(@id AS VARCHAR) )
SET @id = @id + 1
END
2) 现在应用解决方案。
这种情况假设 EMPID 是唯一且已排序的列。
在课程外，您将在不同的列中应用它...
DECLARE @pageSize INT = 20
SELECT * FROM (
SELECT *, PageNumber = CEILING(CAST(EMPID AS FLOAT)/@pageSize)
FROM #employee
) MyQuery
WHERE MyQuery.PageNumber = 1
【讨论】：
可爱的方法，但添加新列可能是开销。【参考方案5】：这些是我在 SQL 服务器端对查询结果进行分页的解决方案。我已经添加了过滤和排序的概念。当您在 Gridview 中进行分页、过滤和排序时，它非常有效。
在测试之前，您必须创建一个示例表并在该表中插入一些行：（在现实世界中，您必须考虑您的表字段来更改 Where 子句，也许您在选择的主要部分有一些连接和子查询）
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 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.
SELECT
Data.ID,
Data.Name,
Data.Tel
FROM
(
SELECT
ROW_NUMBER()
OVER( ORDER BY
CASE WHEN @SortByField = 1 AND @SortOrder = 'ASC'
THEN VLT.ID END ASC,
CASE WHEN @SortByField = 1 AND @SortOrder = 'DESC'
THEN VLT.ID END DESC,
CASE WHEN @SortByField = 2 AND @SortOrder = 'ASC'
THEN VLT.Name END ASC,
CASE WHEN @SortByField = 2 AND @SortOrder = 'DESC'
THEN VLT.Name END ASC,
CASE WHEN @SortByField = 3 AND @SortOrder = 'ASC'
THEN VLT.Tel END ASC,
CASE WHEN @SortByField = 3 AND @SortOrder = 'DESC'
THEN VLT.Tel END ASC
) AS RowNum
,*
FROM VLT
WHERE
( -- We apply the filter logic here
CASE
WHEN @FilterType = 'None' THEN 1
-- Name column filter
WHEN @FilterType = 'Contain' AND @FilterColumn = 1
AND ( -- In this case, when the filter value is empty, we want to show everything.
VLT.ID LIKE '%' + @FilterValue + '%'
OR
@FilterValue = ''
) THEN 1
WHEN @FilterType = 'NotContain' AND @FilterColumn = 1
AND ( -- In this case, when the filter value is empty, we want to show everything.
VLT.ID NOT LIKE '%' + @FilterValue + '%'
OR
@FilterValue = ''
) THEN 1
WHEN @FilterType = 'Match' AND @FilterColumn = 1
AND VLT.ID = @FilterValue THEN 1
WHEN @FilterType = 'NotMatch' AND @FilterColumn = 1
AND VLT.ID <> @FilterValue THEN 1
-- Name column filter
WHEN @FilterType = 'Contain' AND @FilterColumn = 2
AND ( -- In this case, when the filter value is empty, we want to show everything.
VLT.Name LIKE '%' + @FilterValue + '%'
OR
@FilterValue = ''
) THEN 1
WHEN @FilterType = 'NotContain' AND @FilterColumn = 2
AND ( -- In this case, when the filter value is empty, we want to show everything.
VLT.Name NOT LIKE '%' + @FilterValue + '%'
OR
@FilterValue = ''
) THEN 1
WHEN @FilterType = 'Match' AND @FilterColumn = 2
AND VLT.Name = @FilterValue THEN 1
WHEN @FilterType = 'NotMatch' AND @FilterColumn = 2
AND VLT.Name <> @FilterValue THEN 1
-- Tel column filter
WHEN @FilterType = 'Contain' AND @FilterColumn = 3
AND ( -- In this case, when the filter value is empty, we want to show everything.
VLT.Tel LIKE '%' + @FilterValue + '%'
OR
@FilterValue = ''
) THEN 1
WHEN @FilterType = 'NotContain' AND @FilterColumn = 3
AND ( -- In this case, when the filter value is empty, we want to show everything.
VLT.Tel NOT LIKE '%' + @FilterValue + '%'
OR
@FilterValue = ''
) THEN 1
WHEN @FilterType = 'Match' AND @FilterColumn = 3
AND VLT.Tel = @FilterValue THEN 1

END
) = 1
) AS Data
WHERE Data.RowNum > @PageSize * (@PageNumber - 1)
AND Data.RowNum <= @PageSize * @PageNumber
ORDER BY Data.RowNum
GO

【参考方案6】：另一个至少从 SQL 2005 开始工作的解决方案是将 TOP 与 SELECT 子查询和 ORDER BY 子句一起使用。
简而言之，检索每页 10 行的第 2 行与检索前 20 行中的最后 10 行相同。这意味着使用 ASC 顺序检索前 20 行，然后使用 DESC 顺序检索前 10 行，然后再使用 ASC 进行排序。
示例：检索页面 2 行，每页 3 行
create table test(id integer);
insert into test values(1),(2),(3),(4),(5),(6),(7),(8),(9),(10);
select *
from (
select top 2 *
from (
select top (4) *
from test
order by id asc) tmp1
order by id desc) tmp1
order by id asc
【讨论】：
TOP 解决了第一页的问题，但没有解决下一页的问题……我需要在有 50 条记录的页面中请求数据。我用的第一页选择 TOP 50，好的，但是第二页呢？ 这就是我的示例显示的内容。获取第 2 页的 50 条记录：选择前 100 条记录，然后按倒序排列，选择前 50 条记录。您现在有您的第 2 页记录，但顺序相反。正确地重新排序它们，你就完成了。但那是复杂的代码，你应该只在你被旧的 SQL Server 版本卡住并且无法访问诸如 ROW_NUMBER() 之类的功能时才使用它。【参考方案7】：我用于分页的查询是这个（在 Oracle DB 上）。
SELECT * FROM tableName
WHERE RowNum >= 1
AND RowNum < 20
ORDER BY RowNum;
RowNum - 它是由 DB 提供的变量。对于查询返回的每一行，ROWNUM 伪列返回一个数字，指示 Oracle 从一个表或一组连接行中选择行的顺序。
