Bug description: Can't iterate over a PDOStatement object using foreach()
Description:
------------
I invoke PDO::query() twice, with two different valid
SQL queries from within a class method. (Note: I make sure to
invoke fetchAll() on the PDOStatement object returned by the
first invocation before invoking PDO::query() a second time.
Update: I just found out that if I set the first PDOStatement
object to NULL, everything works as intended. HOWEVER,
invoking fetchAll() should suffice, should it not?) I return
the PDOStatement object generated by the second PDO::query()
invocation. I'm unable to iterate over the object with a
foreach() construct even though there ought to be results.
Invoking fetchAll() on the object returns an empty array.
If I set the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute to
true, I don't have this problem, but I'm pretty sure I
shouldn't have it either way.
Reproduce code:
---------------
http://pastebin.com/825493
Expected result:
----------------
I expect to be able to iterate over rows associated with
$broken_iterable_results ... or I would expect for
$broken_iterable_results->fetchAll() to return rows associated
with the PDOStatement object. At the very least, I expect for
some error to be generated if I'm doing anything wrong.
Note: With PDO::ERRMODE_EXCEPTION set to true, there is an
exception thrown.
Actual result:
--------------
Iterating over $broken_iterable_results results does nothing.
Invoking $broken_iterable_results->fetchAll() returns an
empty array.
