Referencing the entire row in an insert trigger

Question

I am trying to replace having to do the following sort of queries repeatedly by using a trigger to handle the second 2:
My first query inserts a row and the following 2 queries insert a reference to that row into 2 other tables
so I want to create a trigger which will insert the reference into the 2 other tables.
my problem: how do I get this reference in the trigger? I know I can get individual values using :NEW.Column but I can't seem to figure out how to get the whole row.
I can't select the row because its inside the trigger responding to it being inserted so I'd get that mutator error.

Answer 1

Not sure why I sql*plus gives those errors. I get the same.
When I tried to use
print_obj(:new.object_value);
heres the results
SQL> CREATE OR REPLACE TRIGGER TR_BOOKING_INS AFTER INSERT ON BOOKING
2 FOR EACH ROW
3 DECLARE
4 ecode NUMBER(38);
5 thisproc CONSTANT VARCHAR2(50) := 'trap_errmesg';
6
7 BEGIN
8 print_obj(:new.object_value);
9 EXCEPTION
10 WHEN OTHERS THEN
11 ecode := SQLCODE;
12 dbms_output.put_line(thisproc || ' - ' || ecode);
13 dbms_output.put_line('fucking errors');
14 END TR_BOOKING_INS;
