Bug Type: Bug
Bug description:MySQL + EMULATE_PREPARES = false cause HY093 error with non
unique parameters
Description:
------------
PHP:
5.4.16
PDO Client API version:
mysqlnd 5.0.10 - 20111026
MySQL:
5.5.18-log (same on 5.6.10-log)
When using "PDO::ATTR_EMULATE_PREPARES => false" with a PDO prepared
statement,
the query fails if it refers to the same named parameter more than once.
Work OK with "PDO::ATTR_EMULATE_PREPARES => true"
Test script:
---------------
CREATE TABLE IF NOT EXISTS `test` (
`id` int(10) unsigned NOT NULL,
`date` int(10) unsigned NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
------------------------------------------
********************
* Common test code *
********************
$pdo = new PDO('mysql:host=<HOST>;dbname=<DB>', '<USER>', '<PWD>',
array(PDO::ATTR_EMULATE_PREPARES => false));
**********
* Test 1 *
**********
$query = $pdo->prepare('INSERT INTO test(id, date) VALUES(:id, :date) ON
DUPLICATE KEY UPDATE date = :date');
$query->bindValue(':id', 5);
$query->bindValue(':date', time());
if( ! $query->execute())
var_dump($query->errorInfo());
**********
* Test 2 *
**********
$query = $pdo->prepare('INSERT INTO test(id, date) VALUES(:date,
:date)');
$query->bindValue(':date', time());
if( ! $query->execute())
var_dump($query->errorInfo());
**********
* Test 3 *
**********
$query = $pdo->prepare('INSERT INTO test(id, date) VALUES(:date,
:date2)');
$query->bindValue(':date', time());
$query->bindValue(':date2', time());
if( ! $query->execute())
var_dump($query->errorInfo());
Expected result:
----------------
No error and an inserted row in DB for both test 1, 2 and 3.
Actual result:
--------------
Test 1 & 2 don't work and return:
array(3) { [0] => string(5) "HY093" [1] => NULL [2] => NULL }
Test 3 works as it does not refer to the same named parameter more than
once.
- If you change "PDO::ATTR_EMULATE_PREPARES" to "true", all tests work
fine.
