Getting New Values Entered into a Table

Getting New Values Entered into a Table

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. to get it.

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;
