postgre 分层为 DB -> schema -> table 和mysql不一样
创建database
这是真正的创建一个数据库,不推荐
create database ispong_db;
创建schema
create schema schema_name;
建表
CREATE TABLE IF NOT EXISTS users
(
username varchar,
age int
);
插入数据
insert into users(username, age) values ('ispong',18);
视图
create view users_view as select user1.id ,username ,age from user1 left join user2 on user1.id=user2.id
