写出一条Sql语句：取出表A中第31到第40记录（SQLServer,以自动增长的ID作为主键,注意：ID可能不是连续的。

解1: select top 10 * from A where id not in (select top 30 id from A)

演变步骤：

1）select top 30 id from T_FilterWords--取前条

2）select * from T_FilterWords

where id not in (select top 30 id from T_FilterWords)--取id不等于前三十条的

--也就是把前条排除在外

3）select top 10 * from T_FilterWords

where id not in (select top 30 id from T_FilterWords)

--取把前条排除在外的前条，也就是-40条

解2: select top 10 * from A where id > (select max(id) from (select top 30 id from A )as A)

解答3：用ROW_NUMBER实现
