#38737 [NEW]: Invalid DSN doesn't raise exception, connects to server, doesn't select DB

From: mjsabby at gmail dot com Operating system: Fedora Core 5 PHP version: 5.1.6 PHP Bug Type: PDO related Bug description: Invalid DSN doesn't raise exception, connects to server, doesn't select DB Description: ------------ After looking closely at the previous bug, Bug #38736, which I filed, I realized I had an incorrectly formatted DSN string. 'mysql:localhost;dbname=xxx' The above DSN, doesn't throw an exception. It instead goes aheads and connects to the MySQL server, but doesn't end up selecting the database. I found this out (in reference to the previous bug) after I set the PDO mode to throw exceptions at everything to analyze what really was going wrong, to which it threw a SQL STATE 1046 No database selected ... Is this desired functionality or a genuine bug? Reproduce code: --------------- <?php define('DB_DSN', 'mysql:localhost;dbname=xxx'); define('DB_USER', 'xxx'); define('DB_PASS', 'xxx'); try { $dbh = new PDO(DB_DSN, DB_USER, DB_PASS); } catch (PDOException $e) { die($e->getMessage()); } // Didn't catch the exception $dbh->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION); try { $query = $dbh->query("QUERY Does not matter"); } catch { PDOException $e) { echo $e->getMessage(); } $dbh = null; ?> Expected result: ---------------- An exception to be thrown, prompting an invalid DSN or something. -- Edit bug report at http://bugs.php.net/?id=38737&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=38737&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=38737&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=38737&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=38737&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=38737&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=38737&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=38737&r=needscript Try newer version: http://bugs.php.net/fix.php?id=38737&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=38737&r=support Expected behavior: http://bugs.php.net/fix.php?id=38737&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=38737&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=38737&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=38737&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=38737&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=38737&r=dst IIS Stability: http://bugs.php.net/fix.php?id=38737&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=38737&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=38737&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=38737&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=38737&r=mysqlcfg
