SQL Server 分页方案比拼

SQL Server 

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

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

 

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

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

SELECT TOP 璶陪ボ︽计 *
FROM TestTable
WHERE (ID NOT IN
          (SELECT TOP 竒陪ボ︽ id
         FROM 表
         ORDER BY id))
ORDER BY ID

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

 
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
