I don't think there's a direct equivalent in Oracle, but if you'd play around with SUBSTR and concatenation you should be able to get what you want.

What is the purpose of the "stuff" function?

The function works like this

SELECT STUFF('abcdef', 2, 3, 'ijklmn')
GO

Here is the result set:

---------
aijklmnef

(1 row(s) affected)

Like I expected, SUBSTR will do. I had a quick go at it:

My test script:
CREATE OR REPLACE FUNCTION stuff (
   char_expr1   IN   VARCHAR2
 , startpos     IN   NUMBER
 , strlen       IN   NUMBER
 , char_expr2   IN   VARCHAR2
)
   RETURN VARCHAR2 DETERMINISTIC
AS
   v_return   VARCHAR2 (4000);
BEGIN
   IF LEAST (NVL (startpos, 0), NVL (strlen, 0)) >= 0
   THEN
      v_return    :=
            SUBSTR (char_expr1, 1, startpos - 1)
         || char_expr2
         || SUBSTR (char_expr1, startpos + strlen, LENGTH (char_expr1));
   END IF;

   RETURN v_return;
END stuff;
/
sho err

col mystuff format A25

SELECT stuff('HelloWorld',6,0,' ') mystuff
     , 'Hello World'               expected
FROM   dual
/

SELECT stuff('HelloWorld',6,4,NULL) mystuff
     , 'Hellod'                     expected
FROM   dual
/

SELECT stuff('abcdef', 2, 3, 'ijklmn') mystuff
     , 'aijklmnef'                    expected
FROM dual
/

DROP FUNCTION stuff
/


My run:
SQL> @orafaq

Function created.

No errors.

MYSTUFF                   EXPECTED
------------------------- -----------
Hello World               Hello World


MYSTUFF                   EXPECT
------------------------- ------
Hellod                    Hellod


MYSTUFF                   EXPECTED
------------------------- ---------
aijklmnef                 aijklmnef


Function dropped.

Frank, of course I know how to find what is the purpose of stuff. Wink
It was just a way to tell to OP that when he post something that is not Oracle to also post either a definition or an url to this one.
Maybe, I should be more direct.

Michel
