## Selected columns, Group, Order and Limit

Note that you can order association results, but you cannot use `LIMIT` on them.

```php
$result2 = $result->select($expr) // identfiers NOT escaped, so expressions are possible
// multiple calls are joined with a comma

// $column group by
$result2 = $result->groupBy($column);

// $column will be escaped
$result2 = $result->orderBy($column);
$result2 = $result->orderBy($column, 'ASC');
