I'm trying to past all data from a heap table
to a myisam table:
CREATE TABLE `heap_in` (
`id` varchar(32) NOT NULL default '',
`domain` varchar(50) NOT NULL default '',
) TYPE=HEAP;

CREATE TABLE `last_visits` (
`id` varchar(32) NOT NULL default '',
`domain` varchar(50) NOT NULL default '',
KEY `id` (`id`,`domain`)
) TYPE=MyISAM;


Heap table just record the data. heap_in.id and heap_in.domain are not unique.
While I'm inserting data to myisam table I want to insert just one time the same domain(if it is duplicated) for the same id.
example:
heap_in:
id domain
1 google.com
2 yahoo.com
3 altavista.com
1 aol.com
1 google.com
2 yahoo.com

I want this in last_visits:
id domain
1 google.com
2 yahoo.com
3 altavista.com
1 aol.com

never insert the same pair of values..

I hope I could be clear.

Thanks
Andre
