beginner SQL (free) tuts.... Please help

Hi,

I am looking free SQL tuts. I want to understand things like this:

Code:

CREATE TABLE ' edoobc_ user' (
'id' int (10) unsigned NOT NULL auto_increment,
'username' varchar (20) NOT NULL default '',
'password' varchar (50) NOT NULL default '',
'email' varchar (40) NOT NULL default '',
PRIMARY KEY ('id')
) ENGINE=MyISAM AUTO_INCREMENT=1 DEFAULT CHARSET=latin1 AUTO_INCREMENT=1;

Cause right now I don;t understand a thing

Thank you for your time.

 

I know :p

But I don't know how to create it by my own..... I didn't wrote it.... I copied it from some website.....

what does this mean:
unsigned? NOT NULL? auto_increment? or ENGINE=MyISAM!?!?
