--要找到某月中所有周五的具体日期
select to_char(t.d,\'YY-MM-DD\') from (
select trunc(sysdate, \'MM\')+rownum-1 as d
from dba_objects
where rownum < 32) t
where to_char(t.d, \'MM\') = to_char(sysdate, \'MM\') --找出当前月份的周五的日期
and trim(to_char(t.d, \'Day\')) = \'星期五\'
--------
03-05-02
03-05-09
03-05-16
03-05-23
03-05-30
如果把where to_char(t.d, \'MM\') = to_char(sysdate, \'MM\')改成sysdate-90，即为查找当前月份的前三个月中的每周五的日期。
--rownum的用法:
只能用以上符号(<、<=、!=)。
select * from tablename where rownum != 10;返回的是前９条记录。
不能用：>,>=,=,Between...and。由于rownum是一个总是从1开始的伪列，Oracle 认为这种条件 不成立，查不到记录.
另外，这个方法更快：
select * from (
select rownum r,a from yourtable
where rownum <= 20
order by name )
where r > 10
这样取出第11-20条记录!(先选再排序再选)
要先排序再选则须用select嵌套：内层排序外层选。
rownum是随着结果集生成的，一旦生成，就不会变化了；同时,生成的结果是依次递加的，没有1就永远不会有2!
rownum 是在 查询集合产生的过程中产生的伪列，并且如果where条件中存在 rownum 条件的话，则:
1： 假如 判定条件是常量，则：
只能 rownum = 1, <= 大于1 的自然数， = 大于1 的数是没有结果的， 大于一个数也是没有结果的
即 当出现一个 rownum 不满足条件的时候则 查询结束 this is stop key!
2: 当判定值不是常量的时候
若条件是 = var , 则只有当 var 为1 的时候才满足条件，这个时候不存在 stop key ,必须进行 full scan ,对每个满足其他where条件的数据进行判定
选出一行后才能去选rownum=2的行……
