Bonjour,

En D4 sous W98 j'ai �crit

with sql do
begin
	add ('SELECT nom,prenom,substring(date,4,7) as exptri from' +
source);
	add ('ORDER by exptri');
end;

D4 me sort
Le projet PSAISRS;exe a provoqu� une classe d'exception EDBEngineError
avec le message 'Utilisation incorrecte du mot clef. El�m�nt : ,4,7)
Num�ro de ligne 1

Une erreur de syntaxe ? Mais comment fallait-il �crire ?

Merci.
