# Default Values

> Setting default schema.

Sometimes, you may want to set default values for item fields

```rust theme={null}
N::NodeType {
  field1: String DEFAULT "default",
  field2: U32 DEFAULT 0
}
```

Helix will use the default value if a value is not provided when inserting the item.

***

#### Example

In the example below, the `age` field has not been provided when inserting the item so the default value of `0` will be used.

```rust theme={null}
QUERY createUser(name: String) =>
    user <- AddN<User>({name}) 
    RETURN user
```
