表中主键必须为标识列，[ID] int IDENTITY (1,1)

1.分页方案一：(利用Not In和SELECT TOP分页)

语句形式：
SELECT TOP 页记录数量 *
FROM 表名
WHERE (ID NOT IN
(SELECT TOP (每页行数*(页数-1)) ID
FROM 表名
ORDER BY ID))
ORDER BY ID
//自己还可以加上一些查询条件

例:
select top 2 *
from Sys_Material_Type
where (MT_ID not in
(select top (2*(3-1)) MT_ID from Sys_Material_Type order by MT_ID))
order by MT_ID

2.分页方案二：(利用ID大于多少和SELECT TOP分页）

语句形式：
SELECT TOP 每页记录数量 *
FROM 表名
WHERE (ID >
          (SELECT MAX(id)
    FROM (SELECT TOP 每页行数*页数 id FROM 表
          ORDER BY id) AS T)
      )
ORDER BY ID

例:
SELECT TOP 2 *
FROM Sys_Material_Type
WHERE (MT_ID >
          (SELECT MAX(MT_ID)
          FROM (SELECT TOP (2*(3-1)) MT_ID
                FROM Sys_Material_Type
                ORDER BY MT_ID) AS T))
ORDER BY MT_ID

3.分页方案三：(利用SQL的游标存储过程分页)
create procedure SqlPager
@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
