I think you need exception here. It will error out if no row found. It will not go to :  

IF SQL%NOTFOUND THEN. "Freeman, Donald" <dofreeman_at_state.pa.us> wrote: I don't know if it will improve performance but since you know that in a = certain number of cases you will get a SQL%NOTFOUND why not use IF/THEN = to deal with it instead of throwing an exception?

select title, volume, pages, year, journalid into ttl, vol, pg, yr, jid from ref where id=3Drn; begin
select abbrev into jname from journal2abbrev where id=3Djid and medline=3D'Y';
IF SQL%NOTFOUND THEN
select name into jname from journal where id=3Djid; END IF;
end;
