how to select the jsonb value for particular key using JSQuery?

[bibekdw]

is it possible to select the value for the key in json using JSQuery?

Something like this: SELECT value @@ (.color) FROM js_test WHERE value @@ '.color = *'

Basically I am interested to see the value of color key in all the json documents if available. My key could be present in any level inside the json.

Thanks.

I have the same question. Is it possible to use jsquery inside the select part or only in the where?

1. I have doubts about your pseudocode example. The @@ operator returns true/false, so it's not clear to me what and how you want to achieve.
2. Yes, the jsquery functionality can be freely used in the SELECT expression. Example from tests:

select 'asd(zzz < 13)'::jsquery;
     jsquery      
------------------
 "asd"."zzz" < 13
(1 row)``
