[solved]database error when re-importing backup

Hi,

I came across a problem when reimporting wordpress’ database after a backup to move it in another server.

During the importing process I get the following error in phphmyadmin:

Errore

query SQL:

—
— Dump dei dati per la tabella wp_commentmeta
—
INSERT INTO wp_commentmeta ( meta_id , comment_id , meta_key , meta_value )
VALUES ( 3, 3, ‘_wp_trash_meta_status’, ‘0’ ) , ( 4, 3, ‘_wp_trash_meta_time’, ‘1305040047’ ) ;

Messaggio di MySQL:
#1062 – Duplicate entry ‘3’ for key 1

What is this? How can I fix it?

Thanks for any help
