RE: a pl/sql question

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;
