这里使用了SQL2005以上版本的内置函数 row_number()方法;
over里是根据什么进么排序;
rownum为子表的别名;
where t.rownum >=11 and t.rownum <=20 以出十条记录;
select
*
from
(
select Id,Name ,row_number() over ( order by id) as rownum
from category
where
id > 30
)t
where t.rownum >= 11 and t.rownum <= 20
(
select Id,Name ,row_number() over ( order by id) as rownum
from category
where
id > 30
)t
where t.rownum >= 11 and t.rownum <= 20
