PDO and buffered queries

HI all. The PHP.net manual is somewhat unclear on this point, so I thought I'd ask here. Does PDO automatically buffer queries the way that the mysql_* extension does, in order to allow multiple result sets open at the same time? Or is that something that has to be set on the connection, and if so, is that available for all drivers? I ask because I am running into a problem with a query segfaulting on me, but only under PHP 5.1 with PDO from pecl. It ran fine in PHP 5.2.0. The only mention in the manual on this subject is: http://us2.php.net/manual/en/ref.pdo-mysql.php "If this attribute is set to TRUE on a PDOStatement, the MySQL driver will use the buffered versions of the MySQL API. If you're writing portable code, you should use PDOStatement::fetchAll() instead." The sample code there suggests that nothing does buffered queries except the MySQL driver. I find no mention of that anywhere else, though, one way or another. Of course, using fetchAll(), as it suggests, means that I only get arrays, not objects. (Unless I'm misreading those docs, too.) Any PDO experts out there able to shed some light on the situation? I'm thoroughly confused at this point, and the manual is quite unclear on all of the important details I care about. :-) -- Larry Garfield AIM: LOLG42 larry@garfieldtech.com ICQ: 6817012 "If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of every one, and the receiver cannot dispossess himself of it." -- Thomas Jefferson
