Insert Audit Trigger Problems

Question

I am almost entirely new to triggers. I have written this trigger inside the .sql file with the rest of the database (inserts, views, sequences and so on):
create or replace trigger t_customer_changes
after insert on customer
for each row
begin
        if inserting then
                insert into CUSTOMER_AUDIT
                        (customer_id, name, audit_date)
                values
                        (:new.customer_id, :new.name, sysdate);
        end if;
end;
/I get a number of errors. Immediarely after the trigger i get:
Warning: Trigger created with compilation errors.And then on almost every insert statement on most tables i get this:
ORA-04098: trigger 'OC0001.T_CUSTOMER_CHANGES' is invalid and failed re-validationThe customers table is created like this:
customer_id     VARCHAR2(2),
name VARCHAR2(20),
PRIMARY KEY(customer_id)Any ideas?

Answer 1

Does the table customer_audit exist in the same schema as customer? If not, the owner of customer will need insert on customer_audit granted directly to them, and will need to qualify the reference to customer_audit with the owner like:
INSERT INTO owner.customer_audit ... [pre]
