Обсуждение: outer joins
Is there a better/another way to write this: select t1.t1_id, (select count(t2.t2_id) from t2 where t2.t1_id = t1.t1_id) as cnt from t1 I have gotten in the habbit of returning similar resultsets via an outer join. What is the scoop on outer joins? Are they to be included in the next release or does the syntax already exist? What will be the syntax for an outer join?

They will use standard SQL92 syntax. -- Brett http://www.chapelperilous.net/~bmccoy/ --------------------------------------------------------------------------- Hardware, n.: The parts of a computer system that can be kicked.
