#44174 [Opn->Bgs]: PDO throws exception although ERRMODE = WARNING

ID: 44174 Updated by: felipe@php.net Reported By: uwendel at mysql dot com -Status: Open +Status: Bogus Bug Type: PDO related Operating System: Linux PHP Version: 5.3CVS-2008-02-19 (CVS) New Comment: From ext/pdo/README: "Regardless of the error handling mode set on the database handle, if the autocommit mode cannot be changed, an exception will be thrown." Previous Comments: ------------------------------------------------------------------------ [2008-02-19 16:47:39] uwendel at mysql dot com Description: ------------ According to the manual, one can ask PDO to report errors in three different ways. "Errors and error handling PDO offers you a choice of 3 different error handling strategies, to fit your style of application development. ", http://de.php.net/manual/en/ref.pdo.php One of them is: "PDO::ERRMODE_WARNING In addition to setting the error code, PDO will emit a traditional E_WARNING message. This setting is useful during debugging/testing, if you just want to see what problems occurred without interrupting the flow of the application." When using PDO::ERRMODE_WARNING, I would not except to get an exception. However, I see PDO::setAttribute(PDO::ATTR_AUTOCOMMIT) [1] and PDO::rollBack() [2] throwing an exception although I have set setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING) prior to invoking any of the two. Try catching the exception and check the error code/info [3]. You might want to update that one as well. Reproduce code: --------------- [1] nixnutz@ulflinux:~/php53> sapi/cli/php -r 'error_reporting(E_ALL); $pdo=new PDO("sqlite:/tmp/foo.db"); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING); $pdo->setAttribute(PDO::ATTR_AUTOCOMMIT, false);' Fatal error: Uncaught exception 'PDOException' with message 'The auto-commit mode cannot be changed for this driver' in Command line code:1 Stack trace: #0 Command line code(1): PDO->setAttribute(0, false) #1 {main} thrown in Command line code on line 1 [2] nixnutz@ulflinux:~/php53> sapi/cli/php -r 'error_reporting(E_ALL); $pdo=new PDO("mysql:dbname=phptest;unix_socket=/tmp/mysql.sock", "root", "root"); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING); $pdo->setAttribute(PDO::ATTR_AUTOCOMMIT, false); @$pdo->exec("DROP TABLE test"); $pdo->exec("CREATE TABLE test(id INT)"); $pdo->exec("INSERT INTO test(id) VALUES (1)"); var_dump($pdo->rollback());' Fatal error: Uncaught exception 'PDOException' with message 'There is no active transaction' in Command line code:1 Stack trace: #0 Command line code(1): PDO->rollBack() #1 {main} thrown in Command line code on line 1 [3] nixnutz@ulflinux:~/php53> sapi/cli/php -r 'error_reporting(E_ALL); $pdo=new PDO("mysql:dbname=phptest;unix_socket=/tmp/mysql.sock", "root", "root"); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_WARNING); $pdo->setAttribute(PDO::ATTR_AUTOCOMMIT, false); @$pdo->exec("DROP TABLE test"); $pdo->exec("CREATE TABLE test(id INT)"); $pdo->exec("INSERT INTO test(id) VALUES (1)"); try { var_dump($pdo->rollback()); } catch (Exception $e) {; }; var_dump($pdo->errorInfo());' array(1) { [0]=> string(5) "00000" } Expected result: ---------------- No exception - alternatively an updated manual. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=44174&edit=1
