I know how to select data from simple json object using "FROM OPENJSON",
but now I have to select a
AttributeValueId, AttributeId and AttributeName, attributePlainValue and CompanyId for each Attribute. So I dont know how to select data from attributes array and then how to join to this CompanyId which is one level up.
Maybe someone knows how write this query.

Answer 1

As mentioned by #lptr in the comments:
You need to pass the result of one OPENJSON to another, using CROSS APPLY. You can select a whole JSON object or array as a property, by using the syntax AS JSON
select
t1.companyid,
t2.*
from openjson(#j)
with (
companyId int,
attributes nvarchar(max) as json
) as t1
cross apply openjson(t1.attributes)
with
(
attributeId int,
attributeName nvarchar(100),
attributeValueId nvarchar(100),
attributePlainValue nvarchar(100)
) as t2;

For example, you can use code like this.
f1.metaData->"$.identity.customerID" = '.$customerID.'
