It seems not so accurate

I have one doubt here..! I feel you have just called the function using for loop, But how can we say It is recursive ? The function should call its own function again (Function calls itself) is said to be recursive right ??? I am confused.

To *test* the function, I called it in a loop.
But look *inside* the function code. It calls itself.
do not do this

Do not call the function on the very 1st line, a few years ago i accidently did not realize i placed the function in the 1st line and the DB server crashed. If i have any code before it, oracle caught the issue, like null; and oracle did not crash.
CREATE OR REPLACE FUNCTION factorial(n POSITIVE)
RETURN POSITIVE IS
factorial(n - 1);
IF n = 1 THEN
RETURN n * factorial(n - 1);

Yes, that's got endless loop and a lot of memory consumption written all over it :-)
