我在 PostgreSQL 13 中有一个这样的菜单表:
-- Drop table
-- DROP TABLE public.menu_resource;
CREATE TABLE public.menu_resource (
id int4 NOT NULL GENERATED ALWAYS AS IDENTITY,
"name" varchar NOT NULL,
res_type int4 NOT NULL,
created_time int8 NOT NULL,
updated_time int8 NOT NULL,
remark varchar NULL,
"path" varchar NOT NULL,
parent_id int4 NOT NULL,
component varchar NULL,
sort int4 NOT NULL,
name_zh varchar NOT NULL,
tree_id_path varchar NULL,
CONSTRAINT auth_resource_id_seq PRIMARY KEY (id)
);
parent_id
菜单数据看起来像这样,带有一个用和标记的树结构id
:
INSERT INTO public.menu_resource
(id, "name", res_type, created_time, updated_time, remark, "path", parent_id, component, sort, name_zh, tree_id_path)
VALUES(13, 'job', 1, 1632389739938, 1632389739938, NULL, '/app/job', 1, NULL, 2, '求职管理', '5-1-13');

现在我想生成父子id的全路径,比如tree_id_path
for job可能是这样的:5-1-13
,interview可能是这样的5-1-13-14
。我应该怎么做才能让它像这样工作?
