Suppose you are writing a row-level trigger Z on a table X to update an audit table Y with information about inserts into X, and you need to know what a particular new value is that was inserted into X: you can use :new.
The following simple example, with X being a two-field table, illustrates its use:
create or replace trigger Z after insert on X for each rowdeclarebegin if inserting then insert into Y values (:new.field1, :new.field2); end if;end Z;
