Hoe alle landinstellingen in MariaDB te tonen

MariaDB ondersteunt een grote lijst met locales die worden gebruikt door functies zoals DAYNAME() , MONTHNAME() en DATE_FORMAT() .

Hoewel deze landinstellingen beschikbaar zijn voor MariaDB, worden ze standaard niet in een van de systeemtabellen geladen, dus u kunt geen query uitvoeren om ze op te halen.

MariaDB biedt echter een plug-in die doet laad deze in een tabel. Nadat de plug-in is geïnstalleerd, kunt u die tabel opvragen om de beschikbare landinstellingen in MariaDB te retourneren.

Installeer de LOCALES Plug-in

Deze stap hoeft alleen te worden uitgevoerd als dit nog niet eerder is gedaan.

De eerste stap om de landinstellingen te kunnen bekijken, is het installeren van de LOCALES inpluggen. Deze plug-in maakt een LOCALES tabel in de INFORMATION_SCHEMA database en vult vervolgens die tabel met alle landinstellingen die beschikbaar zijn in MariaDB.

Voer deze code uit om de plug-in te installeren:

INSTALL SONAME 'locales';

U kunt ook de INSTALL PLUGIN . gebruiken syntaxis.

Het is ook mogelijk om deze plug-in te installeren wanneer de server opstart. U kunt dit doen door de --plugin-load of de --plugin-load-add opdrachtregelargumenten voor mysqld , of geef ze door in de relevante serveroptiegroep in een optiebestand.

Bekijk de locaties

Nadat de plug-in is geïnstalleerd, wordt de INFORMATION_SCHEMA.LOCALES tabel kan worden opgevraagd. U kunt ook gebruik maken van de SHOW LOCALES opdracht.

De LOCALES Tabel

Hier is een voorbeeld van het opvragen van de INFORMATION_SCHEMA.LOCALES tafel:

SELECT * 
FROM INFORMATION_SCHEMA.LOCALES
LIMIT 10;
