SQL JSON query to extract an object - sql

Question

I think the problem is because I have hard brackets [] in the 'groups' object.
JSON:
declare #json nvarchar(max) = N'{ "agents": [ {
"id": 9544321,
"uuid":"xxxx-xxx-xxxx",
"groups": [
{
"name": "GROUP NAME HERE",
"id": 123456
}
],
"support": true
}]}'
What I'm trying to get to is:
id
uuid
group name
group id
9544321
xxxx-xxx-xxxx
GROUP NAME HERE
123456
And then if there is a second group specified in the 'groups' object that'd be two rows. etc
This is my code so far, but it just leaves the [group name] and [group id] columns blank. I've also tried a cross apply and that didn't work (same result).
select *
from openjson(#json, '$.agents')
with (
id int '$.id',
uuid varchar(60) '$.uuid',
groups nvarchar(max) '$.groups' as json
)
outer apply openjson (groups)
with ([group name] nvarchar(max) '$',
[group id] int '$'
)

Answer 1

Try this:
select *
from openjson(#json, '$.agents')
with (
id int '$.id',
uuid varchar(60) '$.uuid',
groups nvarchar(max) '$.groups' as json
)
outer apply openjson (groups, '$')
with ([name] nvarchar(max),
[id] int
)
Did you find the difference? You have placed the value 'Group Name' which is the value, instead of keys in json.

#BeckyG, you're almost there. Please, pay attention to lines 29 and 30:
DECLARE #json NVARCHAR(MAX) = N'{ "agents": [ {
"id": 9544321,
"uuid":"xxxx-xxx-xxxx",
"groups": [
{
"name": "GROUP NAME HERE",
"id": 123456
},
{
"name": "GROUP NAME HERE 2",
"id": 1234567
}
],
"support": true
}]}';
SELECT agents.id,
agents.uuid,
groups.name [group name],
groups.id [group id]
FROM OPENJSON(#json, '$.agents')
WITH (
id INT '$.id',
uuid VARCHAR(60) '$.uuid',
groups NVARCHAR(MAX) '$.groups' AS JSON
) AS agents
OUTER APPLY OPENJSON (agents.groups)
WITH (
[name] NVARCHAR(MAX) '$.name',
[id] INT '$.id'
) AS groups;
Happy coding!
