please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code (See SQL Formatter) and align the columns in result.
Use the "Preview Message" button to verify.

Post what you already tried.

Regards
Michel

Just for fun.
Is there a shorter way to write it? (there are faster queries but shorter?):
SQL> Def val='RAJ'
SQL> with 
  2    data as (
  3      select substr('&val',level,1) letter, level rn
  4      from dual 
  5      connect by level <= length('&val')
  6    )
  7  select replace(sys_connect_by_path(letter,'/'),'/','') perm
  8  from data
  9  where level = length('&val')
 10  connect by nocycle prior rn != rn
 11  /
PERM
----------------------------------------------------------------
RAJ
RJA
ARJ
AJR
JRA
JAR

6 rows selected.

CREATE OR REPLACE FUNCTION Getname(v_name IN VARCHAR) RETURN char
IS
v_Number NUMBER(10);
v_Str VARCHAR(100);
BEGIN
SELECT LENGTH(v_name) INTO v_Number FROM dual;
FOR I IN 0..v_Number LOOP


DBMS_OUTPUT.PUT_LINE ( 'Name'||);
END LOOP;
RETURN (v_name);
END;

Thanks,
Vijay

I can't read non formatted post.

Please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code (See SQL Formatter) and align the columns in result.
Use the "Preview Message" button to verify.

Also always post your Oracle version (4 decimals) for both side client and server.

No grant needed, everyone can execute the query.
But "SQL*Plus internal error" is quite obvious, isn't it?

Michel
