Question

Does anyone know, if there is a bug in CRUD in delete operations.
DB Adapter:

$this->_db = Zend_Registry::get("db");

I do like this:

$sql = "DELETE FROM premium_items WHERE id = '$id'";
                    $stmt = new Zend_Db_Statement_Pdo($this->_db, $sql); 
                    return $stmt->execute();

and

$sql = "DELETE FROM premium_items WHERE id = ?";
                $stmt = new Zend_Db_Statement_Pdo($this->_db, $sql); 
                return $stmt->execute(array($id));

and

$this->_db->delete('premium_items', "id = '$id'");

Each variant works without any errors but does not do what it has to do.
What can I do in such situation ?

Answer 1

With a Zend_Db_Adapter, try:

$this->_db->delete('premium_items', array("id = ?" => $id));

or, in this particular case you can do:

$this->_db->delete('premium_items', 'id = ' . (int)$id);

(but only do this one if you’re using an integer and you cast it!)
