SQL分页方法

表中主键必须为标识列，[ID] int IDENTITY (1,1)
也可以使用联合主键 id+id2+id3+……
 
1.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
2.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
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*@rowcou
