Rozwiązywanie kodu błędu:1005. Nie można utworzyć tabeli „” (errno:150) Błąd

Utwórz advertisment tabela z domyślnym zestawem znaków jako utf8;

łac.1 kolumny nie są równoważne z utf8 kolumny. Tak więc ograniczenie klucza obcego nie może zostać poprawnie uformowane. Stąd 1005 (ER_CANT_CREATE_TABLE) błąd.

Oto mój dziennik mysql.
