# Clone and Reset

## Clone

At times you may need to duplicate a query.  Using `clone` you have a performant way to duplicate a query without using the `duplicate` method.

{% code title="QueryBuilder" %}

```javascript
var q1 = query.from( "users" ).where( "firstName", "like", "Jo%" );
var q2 = q1.clone();
q2.getFrom(); // "users"
```

{% endcode %}

## Reset

When you need to remove all configuration for a query, you can call the `reset` method.

{% code title="QueryBuilder" %}

```javascript
var q1 = query.from( "users" ).where( "firstName", "like", "Jo%" );
var q2 = q1.reset();
q2.getColumns(); // "*"
```

{% endcode %}
