RE: left outer join

Aaaargh! Why do people use that @#$%! ANSI-standard syntax instead of user friendly "+"!!!! I thought that his query is something like:

 select count(*) from tab1 g1,tab2 g2
 where g1.iuid(+) = g2.yypid
   and g2.yypid is null;

That's what happens when people decide that they should follow standards!
