I think you need exception here. It will error out if no row found. It will not
go to :
IF SQL%NOTFOUND THEN.

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;
