I have a Postgres table which has column of type JSON which has a bunch of JSON objects in them. I want to query the table records and order the results by a value stored in the
You put asc in the fieldname. There's no key named value asc in the json, so data ->> 'value asc' will always return NULL.
You actually want:
select * from table ORDER BY data->>'value' ASC
to match the json, possibly even:
select *
from table
WHERE data ->> 'name' = 'stuff'
ORDER BY data->>'value' ASC
