【问题描述】：
我通过 Clearbit 提供程序使用 API 调用将一些数据提取到本地服务器上的数据库中。关于使用 SQL Server 2017 解析数据一切正常，直到遇到问题。
为了便于理解，我将直接上示例。
这是 JSON 格式的 API 调用输出示例

如果你看一下上面的例子，你会看到"domainAliases": [...]
这就是我仍然需要解析的 JSON 的一部分。
这是我已有的 SQL 解析查询：
SELECT *
, JSON_VALUE(JSONData,'$.name') AS CompanyName
, JSON_VALUE(JSONData,'$.category.sector') AS CategorySector
, JSON_VALUE(JSONData, '$.category.industryGroup') AS CategoryIndustryGroup
, JSON_VALUE(JSONData, '$.category.industry') AS CategoryIndustry
, JSON_VALUE(JSONData, '$.category.subIndustry') AS CategorySubIndustry
, JSON_VALUE(JSONData, '$.category.sicCode') AS CategorySicCode
, JSON_VALUE(JSONData, '$.category.naicsCode') AS CategoryNaicsCode
, JSON_VALUE(JSONData, '$.metrics.employees') AS EmployeesNumber
, JSON_VALUE(JSONData, '$.metrics.employeesRange') AS EmployeesRange
, JSON_VALUE(JSONData, '$.metrics.marketCap') AS MarketCap
, JSON_VALUE(JSONData, '$.metrics.annualRevenue') AS AnnualRevenue
, JSON_VALUE(JSONData, '$.similarDomains') AS SimilarDomains
FROM Domains;
我希望将此数据（“domainAliases”）作为上层查询中的数据存储在其他表中（我知道我已经拥有的解析查询只是一个 SELECT 查询，但我也有一个 UPDATE 版本的查询)。
这是一个示例图片，展示了新表中的成品应该是什么样子的。左边一列叫Company Name，第二列叫Domain Aliases：
现在JSON 数据存储在何处？我将它存储在一个名为JSONData 的列中，表名：Domains，所有这些都存储在一个名为Domainbank 的数据库中。 JSONData 数据类型为 nvarchar(max)。
我需要按公司名称对数据进行分组，并且在公司名称旁边应该有别名域，就像图片示例所示。现在请记住，我将为 10k+ JSONDatas 运行此查询，并且要创建的新表将非常巨大，但只要它全部按公司名称和所有别名域分组，它就应该是好的。一些JSONDatas 没有以正确的格式返回 API 调用，因为他们要么没有找到数据，要么出现了其他问题，所以如果查询在 "domainAliases": [...] 下没有找到任何内容，或者没有甚至找到"domainAliases": [...] 然后我不需要公司出现在新表上。
简单回顾一下：让我们新建一个表（我们称之为AliasDomains），找到"domainAliases": [...]下的数据，同时将公司名称拉出JSON_VALUE(JSONData,'$.name') AS CompanyName，将数据存储在新表中，如上图示例在帖子中，然后按CompanyName分组。
