数据库

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。
查看表结构信息：
select   *   from   information_schema.columns   where   table_name='lessql'
