在多列中解析 JSON

Question

我正在收集一些 API 信息，我编写了一个程序来读取域并查找 API 信息，并在找到信息后将其生成的整个 JSON 文本放入 Microsoft SQL Server 中的列中表。

这是其中一个 JSON 输出的外观：

    {
  "id": "3e3562a7-b160-4fd8-a190-8ca0a5288794",

  ]
}

图片示例：

所以我现在需要做的只是取出一些数据，例如“公司名称”、“类别”（包含所有子类别信息）、“员工”、“员工范围”、“市值”、“年收入” " 和 "similardomains" （这应该作为全文列）并在其自己的列中对每个域进行排序。如果能得到任何帮助或指示，我将非常高兴。

使用 JSON_VALUE 函数，您可以从 JSON 列中提取所有数据

  SELECT * , 
     JSON_VALUE(JsonColumn,'$.name') AS CompanyName
     , JSON_VALUE(JsonColumn,'$.category.sector') AS CategorySector
     , JSON_VALUE(JsonColumn, '$.category.industryGroup') AS CategoryIndustryGroup
     -- etc
  FROM YourTable
