vous manquez certains indices, comme '' OrderID' et tpb' dans la tablette 'OrdersArchive'. La table 'custom_fields' sera toujours très inefficace. Quoi qu'il en soit, je suppose que vous voulez que votre requête s'exécute plus vite, combien plus vite? N'oubliez pas que la plate-forme sur laquelle vous exécutez la requête affecte également la vitesse. –
Les index ajoutés que vous avez mentionnés, stiil mauvais résultats comme interroger 2 minutes. La suppression de la sous-requête à partir de la requête accélère réellement la performance à près de 0,1 s –
La sous-requête renvoie un seul résultat, il n'est donc pas nécessaire d'être une sous-requête. Je ne m'attends pas à ce que MySQL l'exécute pour chaque ligne de OrdersArchive, mais cela pourrait l'être. Puisque vous utilisez PHP, essayez d'abord de faire la sous-requête, puis générez le 'OR ID IN (.....)' avec PHP, donc ce sera un tableau constant d'ID. Combien de factures pourrait-il y avoir? –
