Hi,

Maximum size for VARCHAR2 is 4000. So you cant add 32767 characters to a variable which you have defined with VARCHAR2 datatype.

Below will work

DECLARE
  LEN1  NUMBER;
  STR   VARCHAR2(32767);
BEGIN
  
  STR := RPAD('*', 4000, '*');
  
  SELECT LENGTH(STR) INTO LEN1 FROM DUAL;
  DBMS_OUTPUT.PUT_LINE('LEN1: '||LEN1);
 
END;

Thanks,
Suri

In your first example the database engine overrode your length for the RPAD() call with the SQL limit (4000 characters). In your second example you presented the engine with a 32K string and it hurled. This is because the engine hasn't been programmed to truncate a string which is too long.

If anything I think the first example is inconsistent. Certainly that behaviour is [url http://docs.oracle.com/cd/B28359_01/server.111/b28286/functions147.htm#i78723]not documented.
