Thank you for this bug report. To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. Previous Comments: ------------------------------------------------------------------------ [2006-11-16 05:09:03] jpokotilow at tuneteller dot com I feel that I neglected to mention one important point, which is that I *can* iterate over the PDOStatement object prior to returning it from the class method. The object only becomes dysfunctional when it's operated on outside of the class method in question. ------------------------------------------------------------------------ [2006-11-16 05:03:02] jpokotilow at tuneteller dot com 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. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=39527&edit=1
