# Recipient Functions

The Query Definition server-side JavaScript functions allow you to manipulate queries via server-side JavaScript in the following ways:

- Create
- Retrieve
- Update
- Delete
- Run

## Load

In your server-side JavaScript code, first load the core library using this syntax:

```
Platform.Load("core","1");
```

Use the sample code below as models for your own server-side JavaScript code.

## Initialize

To interact with a query definition via server-side JavaScript, you must first initialize the object. The code below initializes a query definition with the external key of 'myQueryDef'.

```
var qd = QueryDefinition.Init("myQueryDef");
```

Once you initialize the query definition, you can use the applicable server-side JavaScript functions.
