RE: Cleaning up iterators

Unless I'm mistaken, this is automatic. row is no longer in scope once you break out of the loop.

Subject: Cleaning up iterators

Hi all,

I'm thinking of using iterator to iterate over the results of a SQL 
query, something like:

for row in result("SELECT id,name FROM USER") do
   if row.id == 3 then break end
end

but I need to "clean-up" the iterator when it finishes (i.e. after the 
loop) or whenever I have a "break" or a "return" statement.

As far as I understand there's no way to do this, right?

Thanks in advance,
Antonio
