worked best for me is a 'super' table 'node' and 'sub' tables

'node'. Table

OK, I'm starting to think it's a wrongly defined table. The table I would
like to import has following structure:

`ID` int(8) unsigned NOT NULL auto_increment,
`country` char(2) NOT NULL,
`region` char(3) NOT NULL,
`url` varchar(50) NOT NULL,
`name` varchar(50)
Yeah, the question is: how 'country' can be a UNIQUE KEY if countries have
hundreds of cities. In the table, hundreds of cities will have the belong
to the same country, so the no wonder the contry code (which is two
