我要发送的对象带有嵌套数组和数组中的对象。此过程应根据是否存在ID更新表中的数据，如果不存在，则应将其插入表中。执行此过程时，它仅更新外部对象（cases表）和包含caseIdentifierId的标识符数组中的对象。它不会在case_identifiers表中创建新的案例标识符，而应该这样做。标识符数组中的研究者和服务数组应该知道它们属于该标识符，因此已添加了“ importId”。每个标识符对象都有其自己的importId。包含“ seqId”的调查者和服务意味着它们是以前创建的，因此应在表中更新而不是插入。

这个答案来得很晚，希望它还是有帮助的。
您的问题是 TL; TR ，但我想我可以为您指出一种替代方法，该方法使工作更加轻松：尝试将整批商品读取到暂存表中然后从那里继续：
DECLARE @caseObj NVARCHAR(MAX) = N'[

-通过为任何嵌套列表添加APPLY OPENJSON，查询将越来越深入。
-将结果隐式写入物理表

,A.caseName
,identif.caseIdentifierId AS identif_caseIdentifier
,identif.importId AS identif_importId
,identif.identifierName AS identif_identifierName

由此您可以继续。有多种方法：
MERGE进行选择，在您的所有表中使用多个GROUP BY语句。通过这样的操作，我建议始终在两者之间放置一个暂存步骤。
