The correct order is as below.

Trigger firing sequence:

1) Before statement level triggers, if present

2) For each row

a) Before row level triggers, if present

b) After row level triggers, if present

3) Actual Statement

4) After statement level triggers

create table d(col1 number primary key)

create table c(col1 number references d(col1))

create or replace trigger c_b4sttmnt

before insert on c

declare

vnum number;

begin

dbms_output.put_line('c_b4sttmnt');

end;

create or replace trigger c_aftrsttmnt

after insert on c

declare

vnum number;

begin

dbms_output.put_line('c_aftrsttmnt');

end;

create or replace trigger c_aftrrow

after insert on c

for each row

declare

vnum number;

begin

dbms_output.put_line('c_aftrrow');

end;

create or replace trigger c_b4row

before insert on c

for each row

declare

vnum number;

begin

dbms_output.put_line('c_b4row');

end;

Please execute the following command which will fail after first 3 triggers.

insert into c values(1);

c_b4sttmnt

c_b4row

c_aftrrow
