Sure there is. If it's a very simple SQL statement.
I have at various times done all of the following, depending on the complexity
of the statement in question:
SELECT id, foo, FROM foo_table WHERE id=5
(Too short to really bother with splitting up.)
SELECT id, foo, bar, baz
FROM foo_table
INNER JOIN bar_table on a=b
LEFT OUTER JOIN baz_table on b=c
WHERE blah
AND stuff < narf
OR (thingie AND other)
ORDER BY foo
SELECT a.a, a.b, a.c
b.d, b.e, b.f
FROM a
INNER JOIN b ON whatever
ORDER BY a.b, a.c DESC
"Like any other programming language", or rather any language that isn't
Python, formatting matters most to the reader, not to the program. So,
optimize your style for readability. Readability is, of course, partially
subjective so your style will differ from my style, but the key point is
still to optimize the code for when you come back in 3-6 months to add a
feature or find an obscure bug and don't remember what the frel you were
doing.
