Looking through the documentation for the Postgres 9.4 datatype JSONB, it is not immediately obvious to me how to do updates on JSONB columns.
Documentation for JSONB types and functions:
http://www.postgresql.org/docs/9.4/static/functions-json.html
http://www.postgresql.org/docs/9.4/static/datatype-json.html
As an examples, I have this basic table structure:
CREATE TABLE test(id serial, data jsonb);
Inserting is easy, as in:
INSERT INTO test(data) values ('{"name": "my-name", "tags": ["tag1", "tag2"]}');
Now, how would I update the ‘data’ column? This is invalid syntax:
UPDATE test SET data->'name' = 'my-other-name' WHERE id = 1;
Is this documented somewhere obvious that I missed? Thanks.
