Bonjour,

Je voudrais faire un forum avec question, réponse, commentaire.

J'ai fait un select avec un query group mais les réponses ne s'affichent que si elle a au moins un commentaire !!

@

<CFQUERY name="Details2" datasource="#session.dbname#">

   SELECT

  

    Forum_Reponse.RID,

    Forum_Reponse.PID,

    Forum_Reponse.Rmessage,

    Forum_Reponse.RDateReponse,

   

    Forum_Comment.CID,

    Forum_Comment.RID,

    Forum_Comment.PID,

    Forum_Comment.Cmessage,

    Forum_Comment.CDateReponse

   

   FROM Forum_Reponse,Forum_Comment

   WHERE Forum_Reponse.PID=9

    And Forum_Reponse.RID=Forum_Comment.RID

   ORDER BY Forum_Reponse.RDateReponse,Forum_Comment.CDateReponse

@

<CFQUERY name="Details2" datasource="#session.dbname#">

  SELECT

    Forum_Reponse.RID,

    Forum_Reponse.PID,

Avec un IF dans le 2ème groupe pour s'assurer s'il y a un enregistrement.
