Use SQL%found

It's in the manual. :)

        Subject:        Branching logic in PL/SQL, positive instead of exception

Hello,
I'm looking for an example of structured PL/SQL code that does not use exception logic for branching, but instead recognizes that data is found.

As a bad example,
Select col1 from test.table t where exists (select z.zip from zip_table z where t.zip=z.zip ) into v_col1 ;
exception
when no_data_found
begin
select col2 from test.table2 t2 where exists (select z.zip from zip_table z where t2.zip=z.zip) into v_col1 ; ;

   exception
   when no_data_found
     begin
I've checked the books and cannot see how to test for a positive result instead of a negative (exception) result. Does anyone have a good example of branching logic on record found? Thanks, Linda
