How retrieve the statement error

Question

Hi,
When an oracle error occurs beyond to retrieve the Error Code and Error Message with SQLCODE and SQLERRM, I'd like to retrieve also the statement that produces this error.
For example:
CREATE TABLE TAB1
ID NUMBER,
NAME VARCHAR2(32 BYTE)
CREATE TABLE TAB2
ID NUMBER,
NAME VARCHAR2(32 BYTE)
CREATE TABLE LOG_ERROR
OBJ_NAME VARCHAR2(50 BYTE),
ERR_CODE NUMBER,
ERR_MSG VARCHAR2(500 BYTE),
STM_MSG VARCHAR2(1000 BYTE)
I've this trigger:
CREATE OR REPLACE TRIGGER MY_TRG
BEFORE INSERT ON TAB1
FOR EACH ROW
DECLARE
ERR_NUM     NUMBER;
ERR_MSG     VARCHAR2(300);
BEGIN
IF :NEW.ID=3 THEN
INSERT INTO TAB2 (ID, NAME) VALUES ('AAA', 5555);
END IF;
IF :NEW.ID = 7 THEN
INSERT INTO TAB2 (ID, NAME) VALUES ('BBBB','7777');
END IF;
EXCEPTION
WHEN OTHERS THEN
     ERR_MSG:= SUBSTR(SQLERRM, 1, 300);
     ERR_NUM:= SQLCODE;
     INSERT INTO LOG_ERROR (OBJ_NAME, ERR_CODE, ERR_MSG)
VALUES ('MY_TRG', ERR_NUM, ERR_MSG);
END MY_TRG;
When I RUN:
INSERT INTO TAB1 (ID, NAME) VALUES (3, 'MY_NAME');
COMMIT;
I get this error in LOG_ERROR table:
OBJ_NAME.............ERR_CODE...............ERR_MSG.....................STM_MSG
MY_TRG...............-1722..............ORA-01722: invalid number.............
INSERT INTO TAB1 (ID, NAME) VALUES (7, 'YOUR_NAME');
COMMIT;
I get same error in LOG_ERROR table:
OBJ_NAME.............ERR_CODE...............ERR_MSG.....................STM_MSG
MY_TRG...............-1722..............ORA-01722: invalid number.............
I'd like to get:
INSERT INTO TAB1 (ID, NAME) VALUES (3, 'MY_NAME');
COMMIT;
OBJ_NAME.............ERR_CODE...............ERR_MSG..........................STM_MSG
MY_TRG...............-1722..............ORA-01722: invalid number.......INSERT INTO TAB2 (ID, NAME) VALUES ('AAA', 5555)
INSERT INTO TAB1 (ID, NAME) VALUES (7, 'YOUR_NAME');
COMMIT;
OBJ_NAME.............ERR_CODE...............ERR_MSG........................STM_MSG
MY_TRG...............-1722..............ORA-01722: invalid number.......INSERT INTO TAB2 (ID, NAME) VALUES ('BBBB','7777')
How can I retrieve the statement that produces this error in the STM_MSG column?
Thanks in advance!

Answer 1

Error occured due to ID is number type and you are inserting Char in the insert statement. May it looks like you want to swap the values in the insert.
To track the error event may be this?
Modify erro table and add column Event varchar2(200);
theni sert the ven in to error_log table for the error at each event. somthing like this
CREATE OR REPLACE TRIGGER MY_TRG
BEFORE INSERT ON TAB1
FOR EACH ROW
DECLARE
ERR_NUM NUMBER;
ERR_MSG VARCHAR2(300);
lEvent varchar2(200);
BEGIN
IF :NEW.ID=3 THEN
  lEvent:=' Inserting in to tab2 for id 3';
  INSERT INTO TAB2 (ID, NAME) VALUES ('AAA', 5555);
END IF;
IF :NEW.ID = 7 THEN
  lEvent:=' Inserting in to tab2 for id 7';
  INSERT INTO TAB2 (ID, NAME) VALUES ('BBBB','7777');
END IF;
EXCEPTION
WHEN OTHERS THEN
   ERR_MSG:= SUBSTR(SQLERRM, 1, 300);
   ERR_NUM:= SQLCODE;
   INSERT INTO LOG_ERROR (OBJ_NAME, ERR_CODE, ERR_MSG,event)
    VALUES ('MY_TRG', ERR_NUM, ERR_MSG,lEvent);
END MY_TRG;formatted
