	last_name varchar(100) not null,
	status smallint(4)  not null default '1' comment "0: Inactive, 1: Active",

);

insert into users (
	username, password, first_name, last_name)
	values('admin', md5('admin'), "Ecommerce", "Admin");

insert into users set
username = 'admin',
password = md5('admin'),
first_name = "Ecommerce",

insert into users set
username = 'manager',
password = md5('admin'),
first_name = "Ecommerce",
last_name = "Manager";

create table product_images (
	id int(11) not null primary key auto_increment,

insert into customers set
first_name = 'Madhav',

Adding Foreign Key

alter table products add foreign key(category_id) references categories(id);
alter table product_images add foreign key(product_id) references products(id);

alter table cart add foreign key(product_id) references products(id);

alter table orders add foreign key(customer_id) references customers(id);
alter table ordered_items add foreign key(order_id) references orders(id);
alter table ordered_items add foreign key(product_id) references products(id);
