SQLAlchemy transform it into a query that returns no records? I.e.,
LIMIT 0, which MySQL at least allows. Because that's what the Python
equivalent would do:
range()[1420:20]
[]
this is like the argument with the empty in_() clause. i like to err
on the side of no silent failures / assumptions. but i lost the
argument with the in_() clause, so im willing to lose the argument
here. even though i really think python should be raising an error
here too...why doesnt it ?
Because iterating when you're already past the end of something
produces an empty result throughout Python.
range(10, 7)
[]
range(10, 7, -1)
[10, 9, 8]
it = iter([1, 2, 3])
it.next()
1
it.next()
2
it.next()
3
for i in it:
... print Found, i
...
The last 'for' loop could raise an error, but it doesn't in Python or
other languages, it just doesn't loop at all.
