Select Nth Row From A Table In Oracle

How can I select the Nth row from a table in Oracle?

I tried

SELECT PRICE FROM AAA_PRICING WHERE ROWNUM = 2

but that didn't work. Please help!

Based on the classic answer:

http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:127412348064

select * 
  from ( select a.*, rownum rnum
           from ( YOUR_QUERY_GOES_HERE -- including the order by ) a
          where rownum <= N_ROWS )
 where rnum >= N_ROWS
/

Will not works with '=' (will works <2 or >2, but not equal)

so you can

 SELECT Price from (SELECT PRICE, ROWNUM AS RN FROM AAA_PRICING) WHERE RN = 2

To address the reason for this:

The RowNum is a pseudo-column supplied by Oracle. It is generated while the SELECT-clause is being processed. Since the WHERE-clause is handled before the SELECT-clause, the RowNum does not have a proper value yet.

One can argue whether or not it makes sense to have Oracle throw an exception in situation, but because RowNum still is a pseudo-column it's still valid to have it there.

Note: Don't confuse this with RowId, which is an entire different story!

IMPORTANT EDIT:

Note that what I wrote about RowNum is only true for =, >, >=, IN () and maybe others. If you check for, e.g. RowNum < 10, you only get nine records!? I don't know why that is the case!

Select * From
(
    Select Row_Number() OVER (Order by empno) rno, e.* 
    From scott.emp e
)
Where rno in (1, 3, 11)

SELECT PRICE 
FROM (  
  SELECT PRICE,    
  ROWNUM rnum 
  FROM AAA_PRICING
  ORDER BY PRICE ASC
  ) 
WHERE    rnum = 2

If you are on Oracle 12 or above, You can use the result offset and fetch clauses:

SELECT PRICE FROM AAA_PRICING 
offset 1 rows fetch next 1 rows only

SELECT * FROM
(SELECT PRICE, ROWNUM AS RN FROM AAA_PRICING )
WHERE RN = 2;

select * from (Select Price, rownum as rn from(Select * from AAA_PRICING a order by a.Price))
where rn=2;

It will give you 2nd lowest price from the Price column. If you want simply 2nd row remove Order By condition.

ROWNUM is a pseudo column which generates unique pseudo values (equals to the number of records present in the SELECT statement o/p) during the execution of SELECT clause. When this pseudo column is specified with the WHERE clause it's value becomes 1 by default. So it behaves according to the comparison operator specified with it.

SELECT * FROM (
           SELECT ROWNUM RN, E.*
           FROM Emp E
          )
WHERE RN = 10;

select * 
From (select PRICE, DENSE_RANK() over(ORDER BY PRICE desc) as RNO
      From AAA_PRICING
     ) t where RNO=2;

select a.*, rownum rnum
           from ( select * from xyz_menu order by priority desc) a
          where rownum < 5 ;

select * from xyz_menu order by priority desc

creating virtual table and also defining row number in virtual table

note: for oracle

Problem solved!

To select 2nd row in Oracle..

select SEN_NO,ITEM_NO from (select * from master_machine where 
sen_no ='BGCWKKL23'  and rownum <=2 order by 
rownum desc,timestamp asc) where rownum <=1

Thank You!
