BigQuery / Shopify-使用订单号获取跟踪号

Question

我有一个从Shopify导出的BigQuery数据集，我已经将数据集的范围缩小到某个日期范围内的订单号，该订单号包含订单号和一个实现对象数组。我现在需要找回跟踪号和订单号的列表。

样本数据

[
  {
    "order_number": "5545",
    "fulfillments": [
      {
        "tracking_url": null,
        "id": "617029074993",
        "tracking_company": "ups",
        "tracking_number": "Z1234567890"
      },
      {
        "tracking_url": null,
        "id": "617029075334",
        "tracking_company": "ups",
        "tracking_number": "Z1234988901"
      },
      {
        "tracking_url": null,
        "id": "617029036534",
        "tracking_company": "ups",
        "tracking_number": "Z1234987801"
      }
    ],
    "_sdc_batched_at": "2018-11-10 02:46:24.270 UTC",
    "_sdc_sequence": "1541817507934"
  },
  {
    "order_number": "2214",
    "fulfillments": [
      {
        "tracking_url": null,
        "id": "617029223993",
        "tracking_company": "ups",
        "tracking_number": "Z1234456890"
      },
      {
        "tracking_url": null,
        "id": "617024455334",
        "tracking_company": "ups",
        "tracking_number": "Z1234780901"
      }
    ],
    "_sdc_batched_at": "2018-11-10 02:46:21.270 UTC",
    "_sdc_sequence": "1541817545934"
  }
]

预期结果

每行都是订单号和跟踪号的组合

[
  {
    "order_number": "5545",
    "tracking_number": "Z1234567890"
  },
  {
    "order_number": "5545",
    "tracking_number": "Z1234988901"
  },
  {
    "order_number": "5545",
    "tracking_number": "Z1234987801"
  },
  {
    "order_number": "2214",
    "tracking_number": "Z1234456890"
  },
  {
    "order_number": "2214",
    "tracking_number": "Z1234780901"
  }
]

以下是用于BigQuery标准SQL

#standardSQL
SELECT order_number, fulfillment.tracking_number
FROM `project.dataset.table`,
  UNNEST(fulfillments) fulfillment
