# $append

Update records by appending a specified value to the existing value in a column. The $append method is used to add new data to an existing value, typically for text columns, ensuring that the original value is preserved while the new data is appended.

```typescript
await Member.$update({
    $where: { 
        age: { 
            $eq: 16 
        } 
    },
    $update: {
        $append: {
            username: 'sobes'
        }
    }
});
```
