You trimmed out the most important bit. It's rather hard to diagnose
things without a full stack trace. :-)
(It occurs to me that a --verbose option would likely be useful so that
we can tell what SQL queries sqlmetal is executing, though I don't know
how easy this would be to add...)
Another possibility is that MySQL doesn't like your ADO.NET provider.
Sqlmetal will use Mono's included ByteFX.Data ADO.NET provider by
default, and I've seen some reports that this occasionally doesn't work
with recent MySQL releases.
If you have the MySQL.Data assembly, you can use that explicitly by
using the /databaseConnectionProvider option:
sqlmetal "/databaseConnectionProvider=MySql.Data.MySqlClient.MySqlConnection, MySql.Data" ...
I don't know if this will work for you, but it might.
