CREATE TABLE customers (customer_id bigint(20) NOT NULL default '0',
firstname varchar(25) NOT NULL,
lastname varchar(25) NOT NULL,
email varchar(100) NOT NULL,
username char(200) NOT NULL,
password char(200) NOT NULL,
street char(100) NOT NULL,
city char(200) NOT NULL,
PRIMARY KEY (customer_ID)) TYPE=MyISAM;
