Re: SQL COUNT et DISTINCT
Merci beaucoup Jean, je crois qu'on y est
Cependant j'ai beau essayer, j'ai du mal à mettre en place le SUBSTRING pour filtrer ma requête : SELECT COUNT ajoute seulement 1 s'il y a plusieurs prestations du prestataire "004" pour un même patient sur des identifiants de séance LIKE "201812%"
