Definition

A query is used to read data from a GraphQL server.

It specifies exactly which fields should be returned.

Basic Structure

query {
  fieldName {
    subField
  }
}

• query → operation type (optional keyword)
• fieldName → root field (defined in Query type)
• subField → fields of the returned object

Example

query {
  user {
    id
    name
  }
}

Response:

{
  "data": {
    "user": {
      "id": "1",
      "name": "Zeeshan"
    }
  }
}

Operation Name (Optional)

You can name queries for clarity and debugging.

query GetUser {
  user {
    id
    name
  }
}
