JDBC - everything in the same table?

I switched over from using mysql persistence to jdbc yesterday. Thought everything worked fine, but now when I look in my database (mysql) I see that it’s actually writing all values to the same table, item0000. I thought it was supposed to make one table per item? I’m not 100%, but this doesn’t feel right…

I get no errors about this in the log. The only setting (except of course for url, user and password) that I’ve changed in jdbc.cfg is numberDecimalcount, I genereally only want one decimal. I wiped the database in between to let jdbc create it’s own structure.
