Hi,

i want to optimise a query that which take about 2 minutes to display results.
here is the code

Bonjour à tous,

je cherche à optimiser une requête qui prends plus de 87 secondes pour s'exécuter.
merci par avance pour vos idées et suggestion:

SELECT ID, Titre, Prix, Contact, Description,

(SELECT valeur from details where DT.ID = details.ID_Annonce and rubrique='Kilométrage') as Kilometrage,
(SELECT valeur from details where DT.ID = details.ID_Annonce and rubrique='Carburant') as Carburant,
(SELECT valeur from details where DT.ID = details.ID_Annonce and rubrique='Boîte de vitesse') as Boite_Vitesse,
(SELECT valeur from details where DT.ID = details.ID_Annonce and rubrique='Année-modèle') as Annee_modele,
Region, Ville, CodePostal

FROM annonces as DT 

WHERE
DT.Categorie like '%voiture%'
AND (DT.`Export` = '0') AND (DT.`Contact` <> '') AND (char_length(DT.`Contact`) = 10)
