      // this function calls a stored procedure
           $sql = "CALL Delete_User_Details(:userId)";
            try {
                    $db = parent::getConnection();
                    $stmt = $db->prepare($sql);
                    $stmt->bindParam("userId", $userId);
                    $stmt->execute();
                    $id = $stmt->fetchObject();
                    if ($id == null) {
                    $delete_response->createJSONArray("DATABASE_ERROR",0);
                    } else {
                    $delete_response->createJSONArray("SUCCESS",1);
                    }
            } catch (PDOException $e) {
                $delete_response->createJSONArray("DATABASE_ERROR",0);
            }
