Oracle数据库如何获取多条结果集中的第一条或某一条

--获取多条结果集中的第一条，通常会排下序之类的，随你方便，如果你不排序直接用括号里的就行
select * from 
	(select * from table 
	 where 1 = 1 
	 order by value1)
where rownum = 1;

select * from table where rownum = 1 order by value1;

select * from 
	( select rownum id,t1.* from
		 (select t2.* from t2 order by t2.某列) 
	t1)
where id=第几条;

where id=第几条

where id = 5

SELECT *
  FROM (
       SELECT ROW_NUMBER() OVER(
