Yeah, you have to be careful with DB reserved words. Our schema has a
TransactionTable which maps to a Transaction object. Can't name the
table Transaction, too, because that is an SQL word. The easiest thing
for you to do is call your table UserTable (or similar), but name your
class User so it functions as you are expecting.

Subject: Re: Trouble with SQLServerDriver
I'd guess this is because "User" is a SQLServer keyword and it requires
special handling when used as identifier.
We have a bug report already -
http://objectstyle.org/cayenne/lists/cayenne-devel/2005/06/0003.html (I
guess I'll raise it in priority as this seems to come up pretty often).
One workaround would be to use a different name for this table. Another
way (I haven't tested it, but it should probably work) is to enter
[User]
as a table name in CayenneModeler.
Hope this helps
