Warning. Be careful with quotes and double quotes.

 '  = Ok

... So use a real text editor and not a word processor.

CREATE TABLE demo1 (
  id int(10) NOT NULL auto_increment,
  login char(10) DEFAULT '' NOT NULL,
  password char(100),
  fullname char(40) DEFAULT '' NOT NULL,
  url char(60) DEFAULT '' NOT NULL,

CREATE TABLE student (
  id int(10) NOT NULL auto_increment,
  name char(40) DEFAULT '' NOT NULL,

INSERT INTO student VALUES (NULL,'Testeur','Bill');
