what is the difference
- by veilig
I'm not even sure what this is called?
But I'm trying to learn what the difference is between writing a function like this is in plpgsql:
CREATE OR REPLACE FUNCTION foo() RETURNS TRIGGER AS $$
....
$$ LANGUAGE plpgsql;
vs
CREATE OR REPLACE FUNCTION foo() RETURNS TRIGGER AS $foo$
....
$foo$ LANGUAGE plpgsql;
is there a difference when using $$ vs $foo$? why would someone choose one over another?
perhaps I've just missed some documentation explaining the difference. If someone could enlighten me, I'd really appreciate it.
