#44151 [NEW]: Errors not cleaned properly

From: uwendel at mysql dot com Operating system: Linux PHP version: 5.3CVS-2008-02-18 (CVS) PHP Bug Type: PDO related Bug description: Errors not cleaned properly Description: ------------ According to the manual, PDO::errorInfo() returns the error information about the "last operation performed by this database handle", http://www.php.net/manual/en/function.PDO-errorInfo.php What is PDO supposed to return if you perform two operations of which the first fails and the second works fine, like this: [1] THIS IS NO VALID SQL, I HOPE [2] CREATE TABLE test(id int NOT NULL PRIMARY KEY, val VARCHAR(10), grp VARCHAR(10)) Should errorInfo() return the error information from [1] or will the error information be cleared prior to running [2]. In the latter case, the user is given an additional easy way to check if an operation has failed or not. And the latter case (clear info before running [2]) is what I as the desired behaviour. Next question: which elements of the errorInfo() element shall be reset? Currently it seems to me as if the SQLSTATE code is reset to '00000' but some drivers (e.g. PDO/MySQL, PDO/SQLlite, maybe more) do not reset their driver specific fields. Haven't checked if that's an issue caused by code from ext/pdo or from ext/pdo_mydriver. Reproduce code: --------------- --TEST-- PDO Common: PDO->errorInfo(), clear line after error --SKIPIF-- <?php # vim:ft=php if (!extension_loaded('pdo')) die('skip'); $dir = getenv('REDIR_TEST_DIR'); if (false == $dir) die('skip no driver'); require_once $dir . 'pdo_test.inc'; PDOTest::skip(); ?> --FILE-- <?php if (getenv('REDIR_TEST_DIR') === false) putenv('REDIR_TEST_DIR='.dirname(__FILE__) . '/../../pdo/tests/'); require_once getenv('REDIR_TEST_DIR') . 'pdo_test.inc'; $db = PDOTest::factory('PDO', false); $db = PDOTest::factory('PDO', false); @$db->exec('THIS IS NO VALID SQL, I HOPE'); var_dump($db->errorInfo()); var_dump($db->errorCode()); $db->exec('CREATE TABLE test(id int NOT NULL PRIMARY KEY, val VARCHAR(10), grp VARCHAR(10))'); var_dump($db->errorInfo()); var_dump($db->errorCode()); print "done!"; ?> --EXPECTF-- array(3) { [0]=> string(5) "%s" [1]=> int(%d) [2]=> string(%d) "%s" } string(5) "%s" array(3) { [0]=> string(5) "00000" [1]=> NULL [2]=> NULL } string(5) "00000" done!
