Oracle 11g cannot run trigger and insert records - oracle

Question

While running this code I am getting Error message.
CREATE TABLE superheoes
(
sh_name VARCHAR2(20)
);
CREATE OR REPLACE TRIGGER superheroes_audit
BEFORE INSERT OR DELETE OR UPDATE ON superheoes
FOR EACH ROW
ENABLE
DECLARE
v_user VARCHAR2(30);
v_date VARCHAR2(30);
BEGIN
SELECT user,TO_CHAR(sysdate,'DD/MON/YYYY HH24:MI:SS') INTO v_user, v_date FROM dual;
IF INSERTING THEN
INSERT INTO sh_audit (new_name, old_name, user_name, entry_date, operation)
VALUES (:NEW.sh_name, NULL, v_user, v_date, 'Insert');
ELSIF DELETING THEN
INSERT INTO sh_audit (new_name, old_name, user_name, entry_date, operation)
VALUES (NULL, :OLD.sh_name, v_user, v_date, 'Delete');
ELSIF UPDATING THEN
INSERT INTO sh_audit (new_name, old_name, user_name, entry_date, operation)
VALUES ( :NEW.sh_name, :OLD.sh_name, v_user, v_date, 'Update');
END IF;
END;
/
Then upon inserting the values:
INSERT INTO superheoes(sh_name) VALUES ('Supe');
======================================================================
I am getting the following Error message:
Error starting at line : 76 in command -
INSERT INTO superheoes(sh_name) VALUES ('Supe')
Error at Command Line : 76 Column : 13
Error report -
SQL Error: ORA-04098: trigger 'HR.SUPERHEROES_AUDIT' is invalid and failed re-
validation
04098. 00000 - "trigger '%s.%s' is invalid and failed re-validation"
*Cause:
A trigger was attempted to be retrieved for execution and was
found to be invalid. This also means that compilation/authorization
failed for the trigger.
*Action: Options are to resolve the compilation/authorization errors,
disable the trigger, or drop the trigger.

Answer 1

If I create the tables according to the trigger, the trigger works as you wrote it:
CREATE TABLE superheoes (sh_name VARCHAR2(20));
CREATE TABLE sh_audit
(
new_name VARCHAR2(20),
old_name VARCHAR2(20),
user_name VARCHAR2(20),
entry_date VARCHAR2(20),
operation VARCHAR2(20)
);
CREATE OR REPLACE TRIGGER superheroes_audit
BEFORE INSERT OR DELETE OR UPDATE
ON superheoes
FOR EACH ROW
ENABLE
DECLARE
v_user VARCHAR2(30);
v_date VARCHAR2(30);
BEGIN
SELECT USER, TO_CHAR(SYSDATE, 'DD/MON/YYYY HH24:MI:SS')
INTO v_user, v_date
FROM DUAL;
IF INSERTING
THEN
INSERT INTO sh_audit(
new_name,
old_name,
user_name,
entry_date,
operation
)
VALUES (
:NEW.sh_name,
NULL,
v_user,
v_date,
'Insert'
);
ELSIF DELETING
THEN
INSERT INTO sh_audit(
new_name,
old_name,
user_name,
entry_date,
operation
)
VALUES (
NULL,
:OLD.sh_name,
v_user,
v_date,
'Delete'
);
ELSIF UPDATING
THEN
INSERT INTO sh_audit(
new_name,
old_name,
user_name,
entry_date,
operation
)
VALUES (
:NEW.sh_name,
:OLD.sh_name,
v_user,
v_date,
'Update'
);
END IF;
END;
/
The trigger is compiled and works:
SQL> INSERT INTO superheoes(sh_name) VALUES ('Supe');
1 row created.
SQL> select * from sh_audit;
NEW_NAME OLD_NAME USER_NAME ENTRY_DATE OPERATION
-------------------- -------------------- -------------------- -------------------- --------------------
Supe ALEK 21/DIC/2016 15:25:37 Insert
I would check the table structure, schema, privileges, ...

Answer 2

Try this: Its working. Also check if you have execute privilege.
SQL> SELECT * FROM DBA_SYS_PRIVS where grantee = 'SYSUSR' and privilege = 'EXECUTE ANY PROCEDURE' ;
GRANTEE PRIVILEGE ADM
------------------------------ ---------------------------------------- ---
SYSUSR EXECUTE ANY PROCEDURE NO
Trigger:
CREATE OR REPLACE TRIGGER superheroes_audit
BEFORE INSERT OR DELETE OR UPDATE
ON superheoes
FOR EACH ROW
BEGIN
-- SELECT USER, TO_CHAR (SYSDATE, 'DD/MON/YYYY HH24:MI:SS')
-- INTO v_user, v_date
-- FROM DUAL;
IF INSERTING
THEN
INSERT INTO sh_audit (new_name,
old_name,
user_name,
entry_date,
operation)
VALUES (:NEW.sh_name,
NULL,
USER,
TO_CHAR (SYSDATE, 'DD/MON/YYYY HH24:MI:SS'),
'Insert');
ELSIF DELETING
THEN
INSERT INTO sh_audit (new_name,
old_name,
user_name,
entry_date,
operation)
VALUES (NULL,
:OLD.sh_name,
User,
TO_CHAR (SYSDATE, 'DD/MON/YYYY HH24:MI:SS'),
'Delete');
ELSIF UPDATING
THEN
INSERT INTO sh_audit (new_name,
old_name,
user_name,
entry_date,
operation)
VALUES (:NEW.sh_name,
:OLD.sh_name,
User,
TO_CHAR (SYSDATE, 'DD/MON/YYYY HH24:MI:SS'),
'Update');
END IF;
END;

See Demo for Trigger functionality:
Tables:
CREATE TABLE superheoes (sh_name VARCHAR2 (20));
CREATE TABLE sh_audit (new_name varchar2(20),
old_name varchar2(20),
user_name varchar2(30),
entry_date varchar2(30),
operation varchar2(20));
Execution:
SQL> select * from superheoes;
no rows selected
SQL> select * from sh_audit;
no rows selected
SQL> insert into superheoes values('XING');
1 row created.
SQL> commit;
SQL> select * from sh_audit;

ENTRY_DATE OPERATION
------------------------------ --------------------
XING SYSUSR
21/DEC/2016 15:19:41 Insert
