ORA-6512

Question

I wrote below small function in pl/sql
==========================
CREATE OR REPLACE FUNCTION rec_id_chk (record_id IN NUMBER) RETURN CHAR IS
dummy NUMBER;
l_mesg_data VARCHAR2(1000);
BEGIN
SELECT NVL(INSTR (record_id, '-'),0) INTO dummy FROM DUAL;
IF dummy > 0 THEN
l_mesg_data := 'Error Type :'||'{'||record_id||'}'||sysdate||' Record Invalid';
RAISE_APPLICATION_ERROR(-20002,l_mesg_data);
END IF;
RETURN 'T';
END rec_id_chk;
===================
When I run it ; it gives ORA-6512;; any suggestions ?
SQL> select rec_id_chk(-11) from dual;
select rec_id_chk(-11) from dual
ERROR at line 1:
ORA-20002: Error Type :{-11}29-OCT-07 Record number format is invalid
ORA-06512: at "APPS.REC_ID_CHK", line 13

Hi Amar
I don't understand why r u checking "-" sign in a number datatype. If u need to check whether the number is +ve or -ve go for a condition like (number<0). By the way error ORA-06512 comes due to error stack unwinding which is the result of  unhandles exceptions.
