建立表：

CREATE TABLE [TestTable] ( [ID] [int] IDENTITY (1, 1) NOT NULL , [FirstName] [nvarchar] (100) COLLATE Chinese_PRC_CI_AS NULL , [LastName] [nvarchar] (100) COLLATE Chinese_PRC_CI_AS NULL , [Country] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NULL , [Note] [nvarchar] (2000) COLLATE Chinese_PRC_CI_AS NULL ) ON [PRIMARY] GO

插入數(shù)據(jù)：(2萬(wàn)條，用更多的數(shù)據(jù)測(cè)試會(huì)明顯一些) SET IDENTITY_INSERT TestTable ON

declare @i int set @i=1 while @i<=20000 begin insert into TestTable([id], FirstName, LastName, Country,Note) values(@i, ''FirstName_XXX'',''LastName_XXX'',''Country_XXX'',''Note_XXX'') set @i=@i+1 end

SET IDENTITY_INSERT TestTable OFF

-------------------------------------

分頁(yè)方案一：(利用Not In和SELECT TOP分頁(yè)) 語(yǔ)句形式： SELECT TOP 10 * FROM TestTable WHERE (ID NOT IN (SELECT TOP 20 id FROM TestTable ORDER BY id)) ORDER BY ID

SELECT TOP 頁(yè)大小 * FROM TestTable WHERE (ID NOT IN (SELECT TOP 頁(yè)大小*頁(yè)數(shù) id FROM 表 ORDER BY id)) ORDER BY ID

-------------------------------------

分頁(yè)方案二：(利用ID大于多少和SELECT TOP分頁(yè)） 語(yǔ)句形式： SELECT TOP 10 * FROM TestTable WHERE (ID > (SELECT MAX(id) FROM (SELECT TOP 20 id FROM TestTable ORDER BY id) AS T)) ORDER BY ID

SELECT TOP 頁(yè)大小 * FROM TestTable WHERE (ID > (SELECT MAX(id) FROM (SELECT TOP 頁(yè)大小*頁(yè)數(shù) id FROM 表 ORDER BY id) AS T)) ORDER BY ID

-------------------------------------

分頁(yè)方案三：(利用SQL的游標(biāo)存儲(chǔ)過(guò)程分頁(yè)) create procedure XiaoZhengGe @sqlstr nvarchar(4000), --查詢字符串 @currentpage int, --第N頁(yè) @pagesize int --每頁(yè)行數(shù) as set nocount on declare @P1 int, --P1是游標(biāo)的id @rowcount int exec sp_cursoropen @P1 output,@sqlstr,@scrollopt=1,@ccopt=1,@rowcount=@rowcount output select ceiling(1.0*@rowcount/@pagesize) as 總頁(yè)數(shù)--,@rowcount as 總行數(shù),@currentpage as 當(dāng)前頁(yè) set @currentpage=(@currentpage-1)*@pagesize+1 exec sp_cursorfetch @P1,16,@currentpage,@pagesize exec sp_cursorclose @P1 set nocount off

其它的方案：如果沒(méi)有主鍵，可以用臨時(shí)表，也可以用方案三做，但是效率會(huì)低。 建議優(yōu)化的時(shí)候，加上主鍵和索引，查詢效率會(huì)提高。

通過(guò)SQL 查詢分析器，顯示比較：我的結(jié)論是: 分頁(yè)方案二：(利用ID大于多少和SELECT TOP分頁(yè)）效率最高，需要拼接SQL語(yǔ)句 分頁(yè)方案一：(利用Not In和SELECT TOP分頁(yè)) 效率次之，需要拼接SQL語(yǔ)句 分頁(yè)方案三：(利用SQL的游標(biāo)存儲(chǔ)過(guò)程分頁(yè)) 效率最差，但是最為通用

在實(shí)際情況中，要具體分析。
