Ligne 1: Ligne 1:
 +====== Wordpress INNER JOIN plante MySql ======
  
 +Wordpress et certains INNER JOIN plante MySql.
 +
 +Quand je chercher events après une date ça fonctionne, on a seulement des ''OR'' sur les meta contenant la date de fin.
 +
 +Par contre pour chercher events entre 2 dates c'est là que MySql part dans les choux, on a dans ce cas des ''OR'' contenant un ''AND'' sur deux meta.

 +===== La BdD =====
