drop table if exists user_info;
create table if not exists user_info
(
    id    BIGINT GENERATED BY DEFAULT AS IDENTITY NOT NULL COMMENT '主键ID',
    name  VARCHAR(30)                             NULL DEFAULT NULL COMMENT '姓名',

    PRIMARY KEY (id)
);

drop table if exists user_role;
create table if not exists user_role
(
    id      BIGINT GENERATED BY DEFAULT AS IDENTITY NOT NULL COMMENT '主键ID',
    user_id BIGINT                                  NULL DEFAULT NULL COMMENT '用户ID',

drop table if exists role_info;
create table if not exists role_info

    id        BIGINT GENERATED BY DEFAULT AS IDENTITY NOT NULL COMMENT '主键ID',
    role_name VARCHAR(30)                             NULL DEFAULT NULL COMMENT '角色名称',
    PRIMARY KEY (id)
);

然后是初始化数据，自增的话，就不要再传入id了

DELETE
FROM role_info;

INSERT INTO role_info (id, role_name)
VALUES (1, 'admin'),
       (2, 'user'),
       (3, 'guest');
