PostgreSQL 9.2 - Convert TEXT json string to type json/hstore

Question

I have a TEXT column containing valid JSON string.

CREATE TABLE users(settings TEXT);

INSERT INTO users VALUES (\'{\"language\":\"en\",\"gender\":\         


        

Answer 1

Or in a shortest way than Reza:

SELECT settings::json FROM users;

Then, for selecting language for instance:

SELECT settings::json->>'language' FROM users;
