I have made a connection class to a fetchall(pdo::fetch_assoc) Microsoft Access Database (which works). However my problem lies where I'm trying to use this class to execute a simple SQL statement and I receive the error message: Fatal error: Call to a member function fetchALL() on a non-object. I'm fairly new to PDO and have read a lot of articles online but to no avail. I think I understand my problem but not fully, please could someone shed some light on the situation and possibly provide an answer to why i'm getting the error message? connectionClass.php class connection{ public $con; private $dbName; function __construct(){ $this->dbName = $_SERVER["DOCUMENT_ROOT"] . "\database\yakety1new.mdb"; } function connect(){ $this->con = new PDO("odbc:DRIVER={Microsoft Access Driver (*.mdb)}; DBQ=$this->dbName; Uid=Admin; Pwd=;"); $this->con->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_EXCEPTION); return $this->con; } } if (!ini_get('display_errors')) { ini_set('display_errors', '1'); } testIndex.php try{ include_once '\classes\connectionClass.php'; $con = new connection(); $pdoConnection = $con->connect(); $sql = $pdoConnection->prepare("SELECT * FROM celebs"); $result = $pdoConnection->exec($sql); while ($row = $result->fetchALL(PDO::FETCH_ASSOC)) { echo $row['firstname']; echo $row['surname']; } } catch (Exception $e){ echo 'ERROR:'.$e->getMessage(); fi

Are there any errors displayed? –George Brighton Sep 13 '13 at 3:34 You need to check that your database calls are working. I suspect that the query() call is returning false, but if you check the errors from the database, you'll see why –andrewsi Sep 13 '13 at 3:34 I bet $queryku is false or null. –Antoan Milkov Sep 13 '13 at 3:35 It doesn't really matter what it is - it's just not an object :) –George Brighton Sep 13 '13 at 3:35 | show 2 more comments 1 Answer 1 active oldest votes up vote 0 down vote accepted You problem is that your query is invalid.

Parameterise a prepared statement, for heavens sake! –eggyal Sep 26 '13 at 1:07 2 You should surround $sth = $dbh->query(...) in a try catch block as well, you have no guarantee that it will succeed. This is likely the problem, either that - or its possible that it completes and returns NULL. –Zack Newsham S
