Question

create or replace trigger "STUDENT_PERSONAL_DETAIL_T1" 
AFTER insert or update or delete on "STUDENT_PERSONAL_DETAIL" 
for each row 
begin 
  insert into fa1 (s_id,name,class,sec) 
  select reg_no,name,class,sec 
  from inserted 
end;

This is the trigger created using Oracle xe trigger creating interface.

It is created without error but when a insert is called on the table trigger error is shown
trigger failed -ORA-04098 is invalid and failed re-validation.

Guidance and suggestions will help a lot.

Answer 1

You should use:

REFERENCING new AS new
...
BEGIN
     INSERT INTO fa1(s_id, name, class, sec)
          VALUES (:new.reg_no, :new.name, :new.class, :new.sec);
...
