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

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 TestTableWHERE (ID NOT IN (SELECT TOP 20 id FROM TestTable ORDER BY id))ORDER BY ID

SELECT TOP 頁(yè)大小 *FROM TestTableWHERE (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 TestTableWHERE (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 TestTableWHERE (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)asset nocount ondeclare @P1 int, --P1是游標(biāo)的id@rowcount intexec sp_cursoropen @P1 output,@sqlstr,@scrollopt=1,@ccopt=1,@rowcount=@rowcount outputselect 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+1exec sp_cursorfetch @P1,16,@currentpage,@pagesize exec sp_cursorclose @P1set nocount off

其它的方案：如果沒有主鍵，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
