No puedo entender cómo puedo actualizar un elemento en un tipo de datos PostgreSQL 9.3.
Mi ejemplo:
CREATE TABLE "user"
(
id uuid NOT NULL,
password character varying(255),
profiles json,
gender integer NOT NULL DEFAULT 0,
created timestamp with time zone,
connected timestamp with time zone,
modified timestamp with time zone,
active integer NOT NULL DEFAULT 1,
settings json,
seo character varying(255) NOT NULL,
CONSTRAINT id_1 PRIMARY KEY (id)
)
WITH (
OIDS=TRUE
);
ALTER TABLE "user"
OWNER TO postgres;
La parte de json en "perfiles"
{
"Facebook": {
"identifier": "xxxxxxxxxxx",
"profileURL": "none",
"webSiteURL": "none",
"photoURL": "none",
"displayName": "test2 test2",
"description": "none",
"firstName": "test2",
"lastName": "test2",
"gender": 2,
"language": "none",
"age": "none",
"birthDay": "none",
"birthMonth": "none",
"birthYear": "none",
"email": "test@test.com",
"emailVerified": "none",
"Added": null,
"phone": "none",
"address": "none",
"country": "none",
"region": "none",
"city": "none",
"zip": "none"
},
"Google": {
"identifier": "xxxxxxxxxxxxxxxxxxxxxx",
"profileURL": "none",
"webSiteURL": "none",
"photoURL": "none",
"displayName": "test2 test2",
"description": "none",
"firstName": "test2",
"lastName": "test2",
"gender": 2,
"language": "none",
"age": "none",
"birthDay": "none",
"birthMonth": "none",
"birthYear": "none",
"email": "test@test.com",
"emailVerified": "none",
"Added": null,
"phone": "none",
"address": "none",
"country": "none",
"region": "none",
"city": "none",
"zip": "none"
}
}
Estoy usando x-edit para la interfaz, y esperaba que algo como esto funcionara, pero no funciona:
UPDATE public.user
SET "profiles"->'Facebook'->'social'->'facebook' = 'test' WHERE` id='id'
Parece que no puedo encontrar ninguna información sobre cómo actualizar un tipo de datos json.
