Mutations also allows to perform deep mutation at multiple levels.

We use the following schema to demonstrate some examples.

## **Schema** :

```graphql
type Author {
	id: ID!
	name: String! @search(by: [hash])
	dob: DateTime
	posts: [Post]
}
type Post {
	postID: ID!
	title: String! @search(by: [term, fulltext])
	text: String @search(by: [fulltext, term])
	datePublished: DateTime
}

```

### **Example** : Deep Deep mutation using variables

```graphql
mutation DeepAuthor($author: DeepAuthorInput!) {
  DeepAuthor(input: [$author]) {
    author {
      id
      name
      post {
        title
        text
      }
    }
  }
}

```

Variables:

```json
{ "author":
  { "name": "A.N. Author",
    "dob": "2000-01-01",
    "posts": [
      {
        "title": "New post",
        "text": "A really new post"
      }
    ]
  }
}

```

### **Example** : Deep update mutation using variables

```graphql
mutation updateAuthor($patch: UpdateAuthorInput!) {
  updateAuthor(input: $patch) {
    author {
      id
      post {
        title
        text
      }
    }
  }
}

```

Variables:

```json
{ "patch":
  { "filter": {
      "id": ["0x123"]
    },
    "set": {
      "posts": [ {
        "postID": "0x456",
        "title": "A new title",
        "text": "Some edited text"
      } ]
    }
  }
}

```

Deep update mutations are not supported in GraphQl. Also, there is no mutation named `DeepAuthor`.We should fix these docs.

hmm, I don’t know why I still find myself trying to update nested data. Maybe because the docs still says it should, but it doesn’t. Now, to rebuild my mutation to update the nested data in sibling mutations instead of deep mutations.
