Bug #52489 [Bgs]: PDOStatement::execute() errors when querying for backslash and question mark

Edit report at http://bugs.php.net/bug.php?id=52489&edit=1 ID: 52489 User updated by: untold69 at hotmail dot com Reported by: untold69 at hotmail dot com Summary: PDOStatement::execute() errors when querying for backslash and question mark Status: Bogus Type: Bug Package: PDO related Operating System: Windows 7 PHP Version: 5.2.14 Block user comment: N New Comment: The question mark is surrounded by quotes and so should be used as a literal value to query the table column, not as a parameter placeholder. The exact same SQL statement executes fine when using PDO::query, e.g. $result = $pdo->query("SELECT * FROM table WHERE column1 = '\' AND column2 = '?'"); Previous Comments: ------------------------------------------------------------------------ [2010-07-29 17:52:08] degeberg@php.net Sorry, but your problem does not imply a bug in PHP itself.
