我目前正在将 PWA 添加到我的新 Angular 项目中。

但加载网页后，我在控制台中收到错误：

I want to create a table have(id,time) and time (timestamp without timezone) without milliseconds.
And I also want to insert the current time per default.

CREATE TABLE ddd (
    id          serial not null,         
    time        timestamp without time zone default now()
    );

我想在当前数据中添加一个变量.

CREATE TABLE test
(
  id text NOT NULL,
  lat numeric,
  lng numeric,
  CONSTRAINT test_pkey PRIMARY KEY (id)
)

这是我的表:

id        lat       lat
ABC-123   12.05481   14.5844

我想让lat添加0.46367并让lng减去0.6899.如何做到这一点？

id        lat       lat
ABC-123   12.51848   13.8945
