Let's say I have a database table with several common columns such as name, gender, age, ...
Besides I have an additional column using the JSON datatype (available from Postgres 9.2) with arbitrary length and arbitrary fields in JSON:
{"occupation":"football"}
{"occupation":"football", "hair-colour":"black"}
{"hair-style":"curly"}
Using new features of Postgres 9.3 I want to return all rows with occupation = football for instance.
Something like this pseudo: select * from table where json_field.occupation = football
Is there a way of doing this?
If I understood the manual correctly, you can access JSON fields with ->
and ->>
operators. The query would look like:
SELECT *
FROM your_table
WHERE json_field ->> 'occupation' = 'football';
