This is rather important bug, becouse it doesn't permite to full use stored procedures by MySQL, MS SQL etc. programmers.

Multi statement is a different feature than fetching results from a stored procedure! 

Multi statement contradicts the idea of PDO to take measures against SQL injections. Don't use multi statements unless you have a good reason for it. Unfortunately PDO does enable multi statements by default! Its strange to see PDO insist on Prepared Statements for "security reasons" but opening up all SQL injection doors by enabling multi statements by default.

Note that the MySQL server does not support multi statements with native prepared statements (= when turning off PDOs buggy prepared statement emulation).

Issue is fixed in PDO_MYSQLND. Please wait for PDO_MYSQLND.

Please try again using PHP 5.3+ . You can download PHP 5.3+ from snaps.php.net.

Make sure that you try this with PHP 5.3+ and mysqlnd (--with-pdo-mysql=mysqlnd , default). It might not work when using the mysqlclient library (libmysql, --with-pdo-mysql=/path/to/mysql_config)
