    }

    // If an exception occurs when attempting to run a query, we'll format the error
    // message to include the bindings with SQL, which will make this exception a
    // lot more helpful to the developer instead of just the database's errors.
    catch (Exception $e) {
        throw new QueryException( ////// Here's the wrong number.
            $query, $this->prepareBindings($bindings), $e
