SQL formatter?

Does anyone know of a routine for formatting SQL statements in a
structured way? Standalone or for emacs would be fine. I'm thinking of
something that could take a long SQL text statement and format it, e.g.:

select foo from bar where baz and bop and not boo;

becomes

SELECT foo
FROM bar
WHERE baz
AND bop
AND NOT boo
;

Thanks,
Andy
