I am trying to parse a field from a nested JSON using postgresql. The form of a JSON has the following form:
{"Field_1": {"Field_2": {"Field_3": "value_1": "xxx"}}}
I have read the question How do I query using fields inside the new PostgreSQL JSON datatype? and I have searched the proposed links, but I have not found anything to work.
{"Field_1": {"Field_2": {"Field_3": "value_1": "xxx"}}}
I want to parse the xxx
of value_1
.
Your JSON have incorrect syntax, this is correct one:
{"Field_1": {"Field_2": {"Field_3": {"value_1": "xxx"}}}}
Then you can:
select j->'Field_1'->'Field_2'->'Field_3'->'value_1' from (
select '{"Field_1": {"Field_2": {"Field_3": {"value_1": "xxx"}}}}'::jsonb as j
) t
