If you're writing portable code, you should use PDOStatement::fetchAll instead. getAttribute(PDO::ATTR_DRIVER_NAME) == 'mysql') { $stmt = $db->prepare('select * from foo', array(PDO::MYSQL_ATTR_USE_BUFFERED_QUERY => true)); } else { die("my application only works with mysql; I should use \$stmt->fetchAll() instead"); } ?> ]]> PDO::MYSQL_ATTR_LOCAL_INFILE (integer) Enable LOAD LOCAL INFILE. Note, this constant can only be used in the driver_options array when constructing a new database handle. PDO::MYSQL_ATTR_INIT_COMMAND (integer) Command to execute when connecting to the MySQL server. Will automatically be re-executed when reconnecting.

This option is not available if mysqlnd is used, because mysqlnd does not read the mysql configuration files. PDO::MYSQL_ATTR_MAX_BUFFER_SIZE (integer) Maximum buffer size. Defaults to 1 MiB. This constant is not supported when compiled against mysqlnd. PDO::MYSQL_ATTR_DIRECT_QUERY (integer) Perform direct queries, don't use prepared statements. PDO::MYSQL_ATTR_FOUND_ROWS (integer) Return the number of found (matched) rows, not the number of changed rows. PDO::MYSQL_ATTR_IGNORE_SPACE (integer) Permit spaces after function names.

PDO::MYSQL_ATTR_SSL_CAPATH (integer) The file path to the directory that contains the trusted SSL CA certificates, which are stored in PEM format. &version.exists.asof; 5.3.7. PDO::MYSQL_ATTR_SSL_CERT (integer) The file path to the SSL certificate. &version.exists.asof; 5.3.7. PDO::MYSQL_ATTR_SSL_CIPHER (integer) A list of one or more permissible ciphers to use for SSL encryption, in a format understood by OpenSSL. For example: DHE-RSA-AES256-SHA:AES128-SHA &version.exists.asof; 5.3.7. PDO::MYSQL_ATTR_SSL_KEY (integer) The file path to the SSL key. &version.exists.asof; 5.3.7.
