用SQL实现分页的三种方法
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 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
