Previous Comments: ------------------------------------------------------------------------ [2005-07-14 03:49:35] james at safesearching dot com Description: ------------ The code below works fine in 5.1.0b2 for me. In 5.1.0b3 and CVS, however, the code produces an error and segfaults. In b3/CVS the table is created and the value is inserted. $db->query('SELECT * FROM foo') returns false and causes the invalid argument error. $stmt->execute() returns false. Accessing $stmt->getColumnMeta() causes a segfault. Throwing a $stmt->fetch() between execute() and getColumnMeta() produces the correct results. (but query() obviously still returns false) Reproduce code: --------------- header('Content-type: text/plain'); $db = new PDO('mysql:dbname=test;host=localhost','**','**'); $db->query('CREATE TABLE `foo` ( `bar` INT NOT NULL );'); $db->query('INSERT INTO foo VALUES(1)'); var_dump($db->query('SELECT * FROM foo')); foreach ($db->query('SELECT * FROM foo') as $row) { print_r($row); } $stmt = $db->prepare('SELECT * FROM foo'); $stmt->execute(); print_r($stmt->getColumnMeta(0)); Expected result: ---------------- object(PDOStatement)#2 (1) { ["queryString"]=> string(17) "SELECT * FROM foo" } Array ( [bar] => 1 [0] => 1 ) Array ( [native_type] => LONG [flags] => Array ( [0] => not_null ) [name] => bar [len] => 11 [precision] => 0 [pdo_type] => 2 ) Actual result: -------------- bool(false) Warning: Invalid argument supplied for foreach() in test.php on line 10 Program received signal SIGSEGV, Segmentation fault.
