Re: how to determine OID of the row I just inserted???

What someone told me was to do this:

	insert into address (street) values ('Penny Lane');
	update customer 
        set address = 
         (select id 
          from address
          where street = 'Penny Lane')
        where name = 'X';

Obviously, there can only be one id for 'Penny Lane'.
