我不知道如何更新PostgreSQL 9.3数据类型中的元素。
我的例子:
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;
“个人资料”中的json部分
{
"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"
}
}
我在前端使用x-edit,但我希望这样的方法行得通,但它不行:
UPDATE public.user
SET "profiles"->'Facebook'->'social'->'facebook' = 'test' WHERE` id='id'
我似乎找不到有关如何更新json数据类型的任何信息。
