Zdarza się podczas importowania bazy, że otrzymujemy taki błąd:
MySQL Error : Duplicate entry 'XXX' for key 1

Najczęściej błąd powodują modyfikacje w bazie. Usuń wszystkie i spróbuj ponownie.

Przyczyną może być również problem ze zgodnością wersji MySQL. Wtedy też baza nie potrafi się dostosować. Aby to poprawić wyślij poniższe zapytania do bazy:

miałem to i pomogło usunięcie z bazy treści odpowiedzialnej za wyszukiwarkę, czyli indeksu wyszukiwarki.
Najlepiej usunąć zanim się zgra bazę.

Zależy czym się wgrywa. Jeżeli posiada się ssh, to za pomocą mysql pomoże parametr -f [--force], natomiast przy pomocy mysqlimport --replace oraz ew. --ignore.

Seba a mógłbyś ułożyć komendę z parametrem -f [--force]?

bo ja wgrywam bazę z wymuszonym kodowaniem

mysql -u root -p --default-character-set=latin2 baza < baza.sql

ale wywala mi Duplicate entry

i chciałbym gotowe zapytanie z wymuszonym kodowaniem i z parametrem -f [--force]

mysql -f reszta

:]

PS. Polecam mysqlimport zainstalować, wchodzi to w skład pakietu mysql-client.
