Re: Reading schema information

Please note, I am still using :

Connection conn = DriverManager.getConnection(info.getUrl(),
info.getUser(), info.getPassword());

DatabaseMetaData metaData = conn.getMetaData();

So I am getting the meta data of the whole data base, and I didn't try
your method yet. You method obtains the meta data for each table as
far as I understand.
