Description:
It would be very interesting to provide support for issuing non-blocking queries in the C/PHP API. I know nothing about the underlying C implementation but I would really like to be able to send a query to the MySQL server without blocking the execution of the program. By periodically checking the status of the connection I would know if the query completed and if a result set is available. As per PHP Manual, this feature exists in the PostgreSQL API, if I wasn't clear enough here is a direct link to it: http://www.php.net/manual/en/function.pg-send-query.php

The new events feature in MySQL 5.1 allows creation of some statements which will run in the background, once or many times.

Events in MySQL 5.1 (see http://dev.mysql.com/doc/refman/5.1/en/events-overview.html) allows to implement this functionality.
