Just to add another bit of nitpicking. What we call "old', Oracle or "traditional" SQL is also ANSI SQL (without the outer join extension which isn't mentioned in the subject line but everyone seems to use in the examples) just an older ANSI standard.
Outer joins were however the subject matter of the original post. "I will have to write a lot of queries involving outer joins which syntax should I use" is my precis. I like the use of traditional as well, it carries less, or maybe different, emotional baggage.
I'm also a bit surprised that no-one has mentioned database independent code (but as I hate database independent apps I won't :( ).
