diffrence between ROWNUM an d LEVEL

K NMay 27 2013 — edited May 27 2013
hi,

i just saw the thread {thread:id=2541136}
SELECT	SUBSTR ('INDIA', LEVEL, 1)	AS letter
FROM	dual
CONNECT BY	LEVEL	<= LENGTH ('INDIA');

and

SELECT	SUBSTR ('INDIA', ROWNUM, 1)	AS letter
FROM	dual
CONNECT BY	ROWNUM	<= LENGTH ('INDIA');
are giving same result. so what is the difference?
