Salut!
�a fais longtemps que j'ai pas fais de MapBasic...
mais moi j'essaierais de prendre un alias pour le nom de la variable...
ou bien, si tu veux �tre s�r du r�sultat, prend l'option RUN COMMAND pis
construit en string en une ligne l'instruction au complet.. genre :
Run Command "Add Column "+""""+Table_Buffers+""""+" ("+ ColName +
"""(Somme)"""+" Float) From "+Table_Data+" Set"
ainsi t� sur de ton coup, mais je sais pas si tu es un adepte de Run
Command...
au pire affiche a l ecran le r�sultat de la string pour voir

>Accident: Real name of a field (Table_Data)
>Dim ColName As String
>ColName = "Accident"
>--------------
>1.
>Add Column "Table_Buffers" ( ColName + "(Somme)" Float) From Table_Data Set
>To sum(Accident) Where within Dynamic
>IT WORKS WELL!!
