Home -> Community -> Mailing Lists -> Oracle-L -> RE: URGENT - HELP ORA-06502:
You could be right, but:
Select MTSN, sum(length(MEMO_TEXT))
From NC_MEMO_TEXT Group by MTSN;
Should tell, if "l_str" is big enough to hold the result of concatenation.

Subject: RE: URGENT - HELP ORA-06502:
Actually could it be that while pl/sql supports a varchar2 being up to
32K
in size that the calling environment only supports a varchar2 being as
large
as the database supports: 4,000 bytes?
How large is the string returned by Fmemo_text? Can you test with a
value
that will return under 2K and see if the error still occurs or if the
function works?

What error says, is that l_str variable in FUNCTION Fmemo_text is too small to hold the result of concatenation.

Subject: URGENT - HELP ORA-06502:
Hi,
I have the following 2 Tables:
CONCAT_MEMO_TEXT -
MTSN NUMBER(10)
MEMO_TEXT VARCHAR2(4000)
NC_MEMO_TEXT -
MTSN NUMBER(10) TEXT_ORDER NUMBER(10) MEMO_TEXT VARCHAR2(255) R_STATUS VARCHAR2(1)
This function:
CREATE OR REPLACE FUNCTION Fmemo_text (p_mtsn IN NUMBER)
return VARCHAR2 is
l_str VARCHAR2(10000);
BEGIN
FOR x IN
(SELECT REPLACE(REPLACE(MEMO_TEXT,chr(13),'Z'),CHR(10),'') AS
MEMO_TEXT
FROM NC_MEMO_TEXT
WHERE MTSN = p_mtsn
ORDER BY TEXT_ORDER)
LOOP
l_str := l_str||''||x.memo_text;
END LOOP;
RETURN l_str;
END;
/
I am trying this insert statement:
INSERT INTO CONCAT_MEMO_TEXT (mtsn,memo_text)
(SELECT mtsn,fmemo_text( mtsn ) MEMO_TEXT
FROM nc_memo_text
GROUP BY mtsn);
However i get this error:
ERROR at line 2:
ORA-06502: PL/SQL: numeric or value error: character string buffer too
small
ORA-06512: at line 1
I have tried various settings for l_str in the finction however i keep getting this error.
I have also tried changing the datatype of CONCAT_MEMO_TEXT .MEMO_TEXT
to
Long, clob etc but no luck.
Anyone got any ideas.
Thanks
