简单聚合

您可以使用聚合查询获取节点上的聚合。目前可用的聚合函数是 count。

在以下示例中，我们有一个名为 students 的表，其中包含诸如 firstName、email、age 等字段和关系。

请求

query MyQuery1 {
  students {
    count
    items {
      id
      firstName
    }
  }
}

响应

{
  "data": {
    "students": {
      "count": 7,
      "items": [
        {
          "id": "287cff0a-345b-4cca-9e9a-75a2161238fd",
          "firstName": "James"
        },
        {
          "id": "97fb89ac-e0ad-44f5-b671-24a1b751287c",
          "firstName": "John"
        },
        {
          "id": "429cf99f-4481-49c4-adb4-605731b20eb2",
          "firstName": "Mary"
        },
        {
          "id": "e25c4955-7ea7-4a83-a3de-d4c7427cc9fa",
          "firstName": "Robert"
        },
        {
          "id": "f0852941-f212-4af0-a583-49ccc10ab42b",
          "firstName": "Jennifer"
        },
        {

          "firstName": "Mary"
        },
        {
          "id": "f26032aa-0a4f-4a72-80a7-a66968065a84",
          "firstName": "Elizabeth"
