Meta Values

Read more in guide Working with Meta Values.

These are examples of queries to fetch meta data, and filter results by meta.

Querying meta

Fetch single meta value _thumbnail_id from posts:

{
  posts {
    id
    title
    metaValue(key: "_thumbnail_id")
  }
}

Fetch array meta value upvotes from comments:

{
  comments {
    id
    content
    upvotes: metaValues(key: "upvotes")
  }
}

Filtering by meta

Filter posts where meta key _thumbnail_id exists:

{
  posts(filter: {
    metaQuery: {
      key: "_thumbnail_id",
      compareBy:{
        key: {
          operator: EXISTS
        }
      }
    }
  }) {
    id
    title
    metaValue(key: "_thumbnail_id")
  }
}

Filter users where meta entry nickname has a certain value:

{
  users(filter: {
    metaQuery: {
      key: "nickname",
      compareBy:{
        stringValue: {
          value: "leo"
          operator: EQUALS
        }
      }
    }
  }) {
    id
    name
    metaValue(key: "nickname")
  }
}

Filter comments where meta entry upvotes (which is an array of integers) has either values 4 or 5:

{
  comments(filter: {
    metaQuery: [
      {
        relation: OR
        key: "upvotes",
        compareBy: {
          arrayValue: {
            value: 4
            operator: IN
          }
        }
      },
      {
        key: "upvotes",
        compareBy: {
          arrayValue: {
            value: 5
            operator: IN
          }
        }
      }
  ]}) {
    id
    content
    upvotes: metaValues(key: "upvotes")
  }
}
