SQL Server 存储过程的经典分页

创建表 

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 


插入数据:(2万条,用更多的数据测试会明显一些) 

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 
--------------------------------------------------------------------- 
分页方案一:(利用Not In和SELECT TOP分页) 
语句形式: 

SELECT TOP 10 * 
FROM TestTable 
WHERE (ID NOT IN 
(SELECT TOP 20 id 
FROM TestTable 
ORDER BY id)) 
ORDER BY ID 


SELECT TOP 页大小 * 
FROM TestTable 
WHERE (ID NOT IN 
(SELECT TOP 页大小*页数 id 
FROM 表 
ORDER BY id)) 
ORDER BY ID 

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

分页方案二:(利用ID大于多少和SELECT TOP分页) 
语句形式: 

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 页大小 * 
FROM TestTable 
WHERE (ID > 
(SELECT MAX(id) 
FROM (SELECT TOP 页大小*页数 id 
FROM 表 
ORDER BY id) AS T)) 
ORDER BY ID 
--------------------------------------------------------------------------- 

分页方案三:(利用SQL的游标存储过程分页) 

create procedure XiaoZhengGe 
@sqlstr nvarchar(4000), --查询字符串 
@currentpage int, --第N页 
@pagesize int --每页行数 
as 
set nocount on 
declare @P1 int, --P1是游标的id 
@rowcount int 
exec sp_cursoropen @P1 output,@sqlstr,@scrollopt=1,@ccopt=1,@rowcount=@rowcount output 
select ceiling(1.0*@rowcount/@pagesize) as 总页数--,@rowcount as 总行数,@currentpage as 当前页 
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:如果没有主键,可以用临时表,也可以用方案三做,但是效率会低。 
在实际情况中,要具体分析。
