#46285 [NEW]: lastInsertId() returns "0" when PDOStatement is executed by dereference

From: phpwnd at gmail dot com Operating system: Linux PHP version: 5.3CVS-2008-10-13 (CVS) PHP Bug Type: PDO related Bug description: lastInsertId() returns "0" when PDOStatement is executed by dereference Description: ------------ lastInsertId() always returns "0" after executing a dereferenced native (non-emulated) prepared statement. Storing the PDOStatement in a variable _then_ executing it solves that problem, and so does using emulated prepared statements. PHP was compiled with --enable-debug --with-pdo-mysql=mysqlnd, I haven't tested with other combinations yet. Reproduce code: --------------- <?php $db = new PDO('mysql:dbname=test;unix_socket=/var/run/mysqld/mysqld.sock', 'user', 'password', array( PDO::ATTR_EMULATE_PREPARES => false )); $db->exec('DROP TABLE IF EXISTS test'); $db->exec('CREATE TABLE test (id INT auto_increment, PRIMARY KEY (id))'); $sql = 'INSERT INTO test (id) VALUES (NULL)'; $db->prepare($sql)->execute(); var_dump($db->lastInsertId()); $stmt = $db->prepare($sql); $stmt->execute(); var_dump($db->lastInsertId()); ?> Expected result: ---------------- string(1) "1" string(1) "2" Actual result: -------------- string(1) "0" string(1) "2" -- Edit bug report at http://bugs.php.net/?id=46285&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=46285&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=46285&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=46285&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=46285&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=46285&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=46285&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=46285&r=needscript Try newer version: http://bugs.php.net/fix.php?id=46285&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=46285&r=support Expected behavior: http://bugs.php.net/fix.php?id=46285&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=46285&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=46285&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=46285&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=46285&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=46285&r=dst IIS Stability: http://bugs.php.net/fix.php?id=46285&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=46285&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=46285&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=46285&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=46285&r=mysqlcfg
