实现sqlserver分页查询语句
sqlServer：
一次查询，数据库只返回一页的数据。而不是取出所有的数据。
pagesize： 每页显示记录数
cureentpage：当前页数
select * from ( select TOP pagesize * from ( SELECT TOP pagesize*cureentpage * from my_table ORDER BY id ASC ) as amyTable ORDER BY id DESC ) as bmyTable ORDER BY id ASC
假设共有有8条记录，每页显示3条记录，id 为3，6，7，37
第一页（首页）
select * from ( select TOP 3 * from ( SELECT TOP 3*1 * from my_table ORDER BY id ASC ) as amyTable ORDER BY id DESC ) as bmyTable ORDER BY id ASC
第二页
select * from ( select TOP 3 * from ( SELECT TOP 3*2 * from my_table ORDER BY id ASC ) as amyTable ORDER BY id DESC ) as bmyTable ORDER BY id ASC
第三页（尾页）
select * from ( select TOP 8-2*3 * from ( SELECT TOP 8-3*2 * from my_table ORDER BY id ASC ) as amyTable ORDER BY id DESC ) as bmyTable ORDER BY id ASC
