mySQL JSON Document Store method for inserting data into node 3 levels deep - mysql

Question

I want to take the data from here: https://raw.githubusercontent.com/usnistgov/oscal-content/master/examples/ssp/json/ssp-example.json
which I've pulled into a mySQL database called "ssp_models" into a JSON column called 'json_data', and I need add a new 'name' and 'type' entry into the 'parties' node with a new uuid in the same format as the example.
So in my mySQL database table, "ssp_models", I have this entry: Noting that I should be able to write the data by somehow referencing "66c2a1c8-5830-48bd-8fdd-55a1c3a52888" as the record to modify.
All the example I've seen online seem to force me to read out the entire JSON into a variable, make the addition, and then cram it back into the json_data column, which seems costly, especially with large JSON data-sets.
Isn't there a simple way I can say
"INSERT INTO ssp_models JSON_INSERT <somehow burrow down to 'system-security-plan'.metadata.parties (name, type) VALUES ('Raytheon', 'organization') WHERE uuid = '66c2a1c8-5830-48bd-8fdd-55a1c3a52888'
I was looking at this other stackoverflow example for inserting into JSON:
How to create and insert a JSON object using MySQL queries?
However, that's basically useful when you are starting from scratch, vs. needing to add JSON data to data that already exists.

You may want to read https://dev.mysql.com/doc/refman/8.0/en/json-function-reference.html and explore each of the functions, and try them out one by one, if you're going to continue working with JSON data in MySQL.
I was able to do what you describe this way:
update ssp_models set json_data = json_array_append(
json_data,
'$."system-security-plan".metadata.parties',
json_object('name', 'Bingo', 'type', 'farmer')
)
where uuid = '66c2a1c8-5830-48bd-8fdd-55a1c3a52888';
Then I checked the data:
mysql> select uuid, json_pretty(json_data) from ssp_models\G
*************************** 1. row ***************************
uuid: 66c2a1c8-5830-48bd-8fdd-55a1c3a52888
json_pretty(json_data): {
"system-security-plan": {
"uuid": "66c2a1c8-5830-48bd-8fdd-55a1c3a52888",
"metadata": {
"roles": [
{
"id": "legal-officer",
"title": "Legal Officer"
}
],
"title": "Enterprise Logging and Auditing System Security Plan",
"parties": [
{
"name": "Enterprise Asset Owners",
"type": "organization",
"uuid": "3b2a5599-cc37-403f-ae36-5708fa804b27"
},
{
"name": "Enterprise Asset Administrators",
"type": "organization",
"uuid": "833ac398-5c9a-4e6b-acba-2a9c11399da0"
},
{
"name": "Bingo",
"type": "farmer"
}
]
}
}
}
I started with data like yours, but for this test, I truncated everything after the parties array.
