Can't restore a mysqldumped backup file

[Elmer Claveria]

Hi!

I tried using mysqldump to backup my database and i can't restore it using the $mysql database < backup.sql command. I'm suspecting that the problem is because i'm using the field name KEY. The error lies somewhere here:

CREATE TABLE Bago (
sn varchar(10) NOT NULL default '',
KEY varchar(5) NOT NULL default '',
PRIMARY KEY (sn)
) TYPE=MyISAM;

Are we not allowed to use KEY as a field name? I enclosed it with quotes ('KEY') and it worked!

whew! Anyone? Thanks
