Subject: Jsonb column
Date: Tue, 12 Mar 2019 09:33:31 -0400 (EDT)
Message-ID: <1310583700.228697.1552397611933@connect.xfinity.com> (raw)
I have a table that has a column, properties, of type jsonb.
Based on documentation:
https://www.postgresql.org/docs/10/functions-json.html
To see all key / value pairs laid out as a table structure of columns, I can use function:
jsonb_each(jsonb) which returns:
"setof key text, value jsonb"
Also if I want to see just the keys, I can use function:
jsonb_object_keys(jsonb) which returns:
"Returns set of keys in the outermost JSON object."
, as per documentation.
So why does my output look like this:
SELECT jsonb_pretty(properties) as properties,jsonb_object_keys(properties) as keys,jsonb_each(properties) as json, properties::jsonb ? 'sendTo' as second FROM JMS_MESSAGE
FETCH FIRST 1 ROWS ONLY;
properties | keys | json | second

The above jsonb_each and jsonb_object_keys both return only the first key. The boolean check if some key is in the jsonb column, (properties::jsonb ? 'sendTo'), returns true so I should see it in the returns for jsonb_each and json_object_keys.
Anyone know why I am not seeing all the keys in this row column?
