一、DCL语句
1.创建用户store

create user store identified by store_password;

2.授予权限connect、resource

grant connect,resource to store;

二、DDL语句
1.创建customers表

create table customers (
customer_id integer constraint customers_pk primary key,
first_name varchar2(10) not null,
last_name varchar2(10) not null,
dob date,
phone varchar2(12));

2.创建product_types表

create table product_types (
product_type_id integer constraint product_types_pk primary key,
name varchar2(10) not null);

3.创建products表

create table products (
product_id integer constraint products_pk primary key,
product_type_id integer constraint products_fk_product_types references product_types(product_type_id),
name varchar2(30) not null,
description varchar2(50),
price number(5,2));

4.创建purchases表

create table purchases(
product_id integer constraint purchases_fk_products references products(product_id),
customer_id integer constraint purchases_fk_customers references customers(customer_id),
quantity integer not null,
constraint purchases_pk primary key (product_id,customer_id));

5.创建employees表

create table employees(
employee_id integer constraint employees_pk primary key,
manager_id integer,
first_name varchar2(10) not null,
last_name varchar2(10) not null,
title varchar2(20),
salary number(6,0));

6.创建salary_grades表

create table salary_grades(
salary_grade_id integer constraint salary_grade_pk primary key,
low_salary number(6,0),
high_salary number(6,0));

三、DML语句
1.向customers表插入数据
