How can i get row number from oracle table

I want to get the record number from the oracle table , i have ever used rownum and rowid before but it does not work because rownum can use only with "<"  (lower than) sign i can not use "=" or ">"  ,i want the case that can fix that the data must be in the record 50-100 or something like this because i must manipulate the data that have more than 280,000 record , thanks for advance

You can do this

CREATE VIEW EMPVIEW AS
SELECT EMPNO, ENAME, ROWNUM AS RECORD_NUM
FROM EMP


SELECT * FROM EMPVIEW;

MPNO ENAME      RECORD_NUM
---- ---------- ----------
7369 SMITH               1
7499 ALLEN               2
7521 WARD                3
................


SELECT * FROM EMPVIEW
WHERE RECORD_NUM >= 7 AND RECORD_NUM <= 10
/

MPNO ENAME      RECORD_NUM
---- ---------- ----------
7782 CLARK               7
7788 SCOTT               8
7839 KING                9
7844 TURNER             10

Yes, I agree with crsankar

But, you don't have to create view, You can always make use of INLINE query.
I am afraid because data is large.

In anyway you can try this query.

SELECT * FROM ( SELECT col1,col2,ROWNUM rw_num
                             FROM    table1)
WHERE rw_num BETWEEN 20 AND 30;

Or

You can issue the following query to make it affective & efficient

Suppose the &upper_bound and &lower_bound are the bound records

SELECT * FROM  ( SELECT col1,col2,ROWNUM rw_num
                              FROM    table1
                              WHERE ROWNUM <= &upper_bound)
WHERE rw_num BETWEEN &lower_bound  AND &upper_bound;


Hope this helps you !
