Re: Why oh why don't my updates stick?

The JDBC standard is for autocommit to be off by default. You have to either
commit each transaction or turn autocommit on. The code to do so is

    connection.autocommit(true);

where connection is your preestablished JDBC Connection, the one you will
use to make the updates.

Hope this helps

No... I have no commit... Didn't know I needed one, since it all works
fine on SQL Server.

How would I enable autocommit?  And is there a reason I wouldn't want to
do that?

Mary,

Are you missing a commit or do you have autocommit enabled somewhere?
