After a recent computer crash, I installed a new software package with Apache, PHP and MySQL. I was pleased to see that some of my programs were upgrades. Everything was working fine until I tried to publish some of my database tables online just minutes ago got an unfamiliar error:

#1064 - You have an error in your SQL syntax. Check
the manual that corresponds to your MySQL server
version for the right syntax to use near 'collate
latin1_general_ci NOT NULL default '',
`IDRealm` varc

I looked up "collation" on MySQL's website, but it doesn't yet make sense to me. What's it all about, and - more important - how do I solve this new error MySQL created for me?

Also, I noticed that when I create tables, I no longer
have a choice for InnoDB, so I've been choosing
MyISAM. If I leave it at default, what kind of table
would I get?

Actually, I'm leaning towards MyISAM anyway. I thought
InnoDB were generally considered superior, but when my
computer crashed, I lost most of my InnoDB tables but
none of my MyISAM tables.
