Pretty simple, using $mysqli->prepare($query) crashes the server with the message
"mysqli_stmt::__construct(): Unknown type 18 sent by the server. Please send a report to the developers"
Test script:

The difference is that user is using PDO, I'm using mysqli, but the underlying cause seems to be the same.

Hi, can you tell us what MySQL version you are using and could you produce a bit minimal script that generates the error and the crash. I tried myself with 7.0 and 7.1 but no crash. Here is my table: mysql> create table dt(a datetime(6)); Query OK, 0 rows affected (0,01 sec) mysql> insert into dt values ('2014-09-08 17:51:04.123456'); Query OK, 1 row affected (0,01 sec) mysql> select * from dt; +----------------------------+ | a | +----------------------------+ | 2014-09-08 17:51:04.123456 | +----------------------------+ 1 row in set (0,00 sec) Then on the command line: andrey@poohie:/work/dev/php/php-7.0$ ./php -r '$c=mysqli_connect("127.0.0.1","root","","test"); $s=$c->prepare("select * from dt"); $s->execute();var_dump($s->get_result()->fetch_all());' array(1) { [0]=> array(1) { [0]=> string(19) "2014-09-08 17:51:04" } } And in wireshark I see that FIELD_DATETIME (12) is sent over the wire. Type 18 is DATETIME2, which is DATETIME with microseconds. However, mysqlnd here doesn't see the microseconds as DATETIME is sent. I am curious what triggered the server to send the microseconds and the new type. This is why I would like to see a shorter example of your code that is self contained (or is one small PHP and one small SQL dump file). Thank you very much in advance! AndreyHi, I am able to reproduce with the following: <?php /* CREATE TABLE `type18` ( `tripDay` datetime NOT NULL, KEY `entity_index` (`tripDay`), KEY `day_index` (`tripDay`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1; INSERT INTO `type18` VALUES ('2014-04-03 00:00:00'); */ $foo = mysqli_connect('127.0.0.1', 'root', '', 'test'); $query = "(SELECT DATE_FORMAT(DATE_ADD(MAKEDATE(YEAR(tripDay), 1), INTERVAL MONTH(tripDay) - 1 MONTH),'%c/%e/%y'), tripDay FROM type18 ORDER BY YEAR(tripDay)) ORDER BY YEAR(tripDay)"; $foo->query("set sql_mode=''"); $x = $foo->prepare($query); var_dump($foo->error); ?>Even shorter one: <?php /* CREATE TABLE `type18` ( `tripDay` datetime NOT NULL ) ENGINE=InnoDB; INSERT INTO `type18` VALUES ('2014-04-03 00:00:00'); */ $conn = mysqli_connect('127.0.0.1', 'root', '', 'test'); $conn->query("set sql_mode=''"); $sql = "(SELECT tripDay FROM type18 ORDER BY YEAR(tripDay)) ORDER BY YEAR(tripDay)"; $stmt = $conn->prepare($sql); var_dump($stmt, $conn->error); ?>
