Hi
I have a question,
what is expected result of null strip of
{"a": {"b": null, "c", null"} }
?
Please remember not to top-post.
The above is not legal json, so the answer would be an error.
I believe Pavel means:
{"a": {"b": null, "c": null} }
This is the expected result:
andrew=# select json_strip_nulls('{"a": {"b": null, "c": null} }');
json_strip_nulls
------------------
{"a":{}}
(1 row)
It is NOT expected that we replace an empty object with NULL (and then
strip it if it's a field value of an outer level object).
cheers
andrew
