Bonjour,

À partir du moment où la clause SELECT comporte à la fois des colonnes agrégées et non agrégées, il est obligatoire de coder une clause GROUP BY sur l'ensemble des colonnes non agrégées.

Ce qui donne quelque chose comme :
Code:

1 2 3 4 5 6 7 SELECT date_format(Date,'%d/%m %y ') as datum , max(TmpExt) as TmpExt FROM DAVIS where YEAR(date) =$currentyear and MONTH(date)=$currentmois group by date_format(Date,'%d/%m %y ') order by...

Jai finalement trouve cette solution la si ca peux aider :

Code:

1
2
 
$chartQuery = "SELECT max(Pression) AS Pression_Max ,min(Pression) AS Pression_Min, date_format(Date,'%d/%m %y ') AS datum  FROM DAVIS  where YEAR(Date)=$currentyear and MONTH(Date)= $currentmois group by DATE(Date) DESC";

Merci en tous cas pour votre aide
