How to parse nested JSON array using SQL Server

Question

I am currently able to parse most of a JSON file using SQL Server\'s \"OPENJSON WITH (...\" syntax. However, this particular file contains nested arrays which I do not know how

Answer 1

After MUCH searching I finally discovered the answer to this issue. I simply have to include the Nested Array as another JSON column in my query, like:

WITH
 (DOC_ID                varchar(100)  '$.doc._id',
  DOC_REV               varchar(45)   '$.doc._rev',
  DELY_APPL_NAME        varchar(20)   '$.doc.delivery.application',
  DELY_SENT_BY          varchar(25)   '$.doc.delivery.sender.id',
  DELY_SENT_TYPO        varchar(20)   '$.doc.delivery.sender.type',
  RECIPS                nvarchar(max) '$.doc.delivery.recipients' as JSON,
  PAYLOAD_START_TIME    varchar(30)   '$.doc.payload.startTS',
  ....
  ...
  ..
  ) as my_query

So, I end up with one record per JSON document, with (in this case) a varchar column containing JSON text.

Next, I can run a separate query on this column to parse the JSON and create a "child table" associated with the Parent.
