MariaDB obsługuje dużą listę lokalizacji używanych przez funkcje takie jak DAYNAME() , MONTHNAME() i DATE_FORMAT() .
Chociaż te ustawienia regionalne są dostępne dla MariaDB, domyślnie nie są one ładowane do żadnej z tabel systemowych, więc nie można uruchomić zapytania, aby je pobrać.
Jednak MariaDB udostępnia wtyczkę, która robi załaduj je do tabeli. Po zainstalowaniu wtyczki możesz wysłać zapytanie do tej tabeli, aby zwrócić ustawienia regionalne dostępne w MariaDB.
Zainstaluj LOCALES Wtyczka
Ten krok należy wykonać tylko wtedy, gdy nie został on wcześniej wykonany.
Pierwszym krokiem do wyświetlenia lokalizacji jest zainstalowanie LOCALES podłącz. Ta wtyczka tworzy LOCALES tabela w INFORMATION_SCHEMA bazy danych, a następnie wypełnia tę tabelę wszystkimi ustawieniami narodowymi dostępnymi w MariaDB.
Uruchom ten kod, aby zainstalować wtyczkę:
INSTALL SONAME 'locales';
Możesz alternatywnie użyć INSTALL PLUGIN składnia.
Możliwe jest również zainstalowanie tej wtyczki podczas uruchamiania serwera. Możesz to zrobić, przekazując --plugin-load lub --plugin-load-add argumenty wiersza poleceń do mysqld , lub podając je w odpowiedniej grupie opcji serwera w pliku opcji.
Wyświetl lokalizacje
Po zainstalowaniu wtyczki INFORMATION_SCHEMA.LOCALES tabela może być zapytana. Możesz także użyć SHOW LOCALES Komenda.
